Macaroon Network
Marketplace for agent-purchasable capabilities. Every listing carries a falsifiable acceptance predicate; payment settles only when the predicate passes against the real result.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
UK Haulage Fraud & Identity Check uk-haulage-fraud-identity-check-v1
Cross-references a UK haulage operator's DVSA-declared licence holder name against that company's real, live Companies House officers and persons with significant control (PSC) -- flagging a mismatch, or a recent director/PSC change, the real pattern seen in distressed-acquisition cargo-theft fraud where a haulier's licence still shows the old, legitimate operator while control of the company has quietly changed hands.
live-datacomposition-productSanctions & PEP Screening sanctions-pep-screening-v1
Screen a name in one call against US OFAC SDN, the EU Consolidated Financial Sanctions List, UK OFSI, the UN Security Council Consolidated List, and Wikidata-derived Politically Exposed Persons (PEP) data -- with fuzzy name matching, not exact-only. Real competitor research (2026-09-11) found this exact bundle+fuzzy-match shape is what actually converts in this niche; the single-source exact-match ofac-sanctions-search-v1 listing did not.
Christian Scripture Passage Context christian-scripture-passage-context-v1
Return a requested verse plus up to ten same-chapter verses before and after from a pinned public-domain corpus.
source-labelledpassage-contextprivacy-boundedpublic-domainChristian Scripture Keyword Search christian-scripture-keyword-search-v1
Literal concordance-style search over a pinned public-domain Bible corpus, with bounded source-labelled evidence.
source-labelledliteral-searchprivacy-boundedpublic-domainUK Logistics Operator Risk Check uk-logistics-operator-risk-check-v1
Search DVSA's real, live UK Vehicle Operator Licensing register -- every goods vehicle and PSV operator licence in Great Britain (69,127 operators, updated weekly) -- for a haulier or logistics operator by name. Returns licence status, authorised fleet size, and cross-references the operator's real Companies House status to flag a rare but real risk: a licence that still reads valid while the operator's actual registered company is dissolved or in liquidation.
live-datacomposition-productChristian Scripture Reading Plan christian-scripture-reading-plan-v1
Retrieve one bounded day from a deterministic seven-day gospel, psalm-prayer, or practical-wisdom reading plan using source-labelled public-domain Bible text.
source-labelledprivacy-boundedreading-planpublic-domainChristian Topic Scripture Guide christian-topic-scripture-guide-v1
Return a bounded, source-labelled set of public-domain Bible passages and neutral reflection prompts for one of six predefined topics.
source-labelledprivacy-boundedtopic-guidepublic-domainNHTSA Vehicle Recall Search nhtsa-vehicle-recall-search-v1
Look up official U.S. vehicle safety recalls by make, model, and model year -- campaign number, affected component, defect summary, safety consequence, and remedy. The only source used is the National Highway Traffic Safety Administration's own public API (api.nhtsa.gov). Restricted to recall lookup only for v1; NHTSA safety ratings and complaint records are a different part of the same API family and are not covered.
live-dataofficial-sourcemetadata-onlyFederal Register Search federal-register-search-v1
Search U.S. federal regulatory documents -- final rules, proposed rules, notices, and presidential documents -- by keyword, document type, issuing agency, and publication date range. The only source used is the Federal Register's own public API (federalregister.gov), published by the National Archives and Records Administration's Office of the Federal Register.
live-dataofficial-sourcemetadata-onlyUS Weather Forecast & Alerts us-weather-forecast-alerts-v1
Live multi-day forecast and currently active weather alerts (severe thunderstorm, flood, winter storm, etc.) for a single latitude/longitude point, from the U.S. National Weather Service's own public API (api.weather.gov). Coverage is limited to the United States, its territories, and adjacent coastal/marine zones -- api.weather.gov has no data for points outside that area.
live-dataofficial-sourcemetadata-onlyUK Parliament Search uk-parliament-search-v1
Search live UK Parliament data: Members (current and former MPs and Peers, by name) and Bills (by title). The only sources used are the UK Parliament's own public Members API (members-api.parliament.uk) and Bills API (bills-api.parliament.uk), both unauthenticated. Votes and Divisions data (a different API family) is out of scope for this version.
live-datametadata-onlyChristian Scripture Lookup christian-scripture-lookup-v1
Retrieve a bounded passage from the public-domain Berean Standard Bible or World English Bible with exact source labels and provenance.
source-labelledprivacy-boundedexact-passagepublic-domainScripture-Grounded Salvation Guide christian-salvation-guide-v1

source-labelledprivacy-boundedscripture-guidenon-sacramentalChristian Passage Comparison christian-passage-compare-v1
Compare a bounded passage in the public-domain BSB and WEB without blending or interpreting the source texts.
source-labelledprivacy-boundedtranslation-comparisonpublic-domainScripture-Grounded Devotional Blessing christian-devotional-blessing-v1
Return a deterministic source-labelled devotional blessing for reflection. Payment buys the structured service, not divine favour or a sacrament.
source-labelledprivacy-boundeddevotionalnon-sacramentalChristian Cross References christian-cross-references-v1
Return bounded ranked OpenBible.info cross-reference identifiers with displayed text resolved only from BSB or WEB.
source-labelledprivacy-boundedcross-referencescc-by-attributedPrivate Confession Reflection christian-confession-reflection-v1

source-labelledprivacy-boundedno-free-textnon-sacramentalWorld Bank WDI Indicator Search world-bank-wdi-indicator-search-v1
Search live macroeconomic indicators from the World Bank's World Development Indicators (WDI) database by country and indicator (e.g. GDP, population, inflation, unemployment). Restricted exclusively to WDI, source ID 2 -- the World Bank's own flagship, wholly-owned compiled dataset -- never any of the ~90 other databases the same World Bank API also serves, some of which carry third-party reuse terms. Country and indicator can be given as free text (resolved against the World Bank's own reference lists) or as exact ISO codes / indicator codes.
live-datametadata-onlyDrug/Medicine Metadata Search drug-medicine-metadata-search-v1
Search live drug and medicine metadata from the U.S. FDA's openFDA API: brand/generic name, active ingredients with strength, dosage form, route, manufacturer/labeler, product type, marketing status, and NDC codes -- plus an optional short (~400 character) label excerpt (purpose or indications only) and an optional recall/enforcement flag. Composed entirely from openFDA's NDC Directory, Drug Label, and Drug Enforcement APIs, all public domain (CC0 1.0 Universal). Never returns full label sections, dosage/administration instructions, drug-interaction or contraindication text, adverse-reaction text, device (GMDN) nomenclature, or personalised medical advice.
live-datametadata-onlycomposition-productClinical Trials Search clinical-trials-search-v1
Search live clinical trial records from ClinicalTrials.gov: status, phase, conditions, interventions, lead sponsor, eligibility (sex, age range, a short truncated criteria excerpt), and locations. The only source used is the U.S. National Library of Medicine's public ClinicalTrials.gov API v2, available at no charge. Full eligibility-criteria text, full descriptions, and investigator/recruitment contact details are never returned -- only source-linked, truncated summary metadata.
live-datametadata-onlyUniversal Macaroon Search universal-macaroon-search-v1
Discover which Macaroon Network service, endpoint, or data product to call next. Searches Macaroon's own published catalogue -- title, category, description, price, and trust evidence metadata -- and returns a short, source-linked ranked list plus a safe recommended next call for each match. A thin wrapper over this registry's own existing semantic search and router infrastructure; does not execute matched services, does not call any underlying paid endpoint, and does not duplicate a matched service's own output.
live-datametadata-onlycomposition-productGrant & Tender Opportunity Search grant-tender-opportunity-search-v1
Search live UK/EU public procurement tenders and US federal grant opportunities in one call: UK Contracts Finder, UK Find a Tender Service, EU TED (Tenders Electronic Daily), and Grants.gov. Returns source-linked metadata only -- title, buyer/funder, deadline, value, region, category codes, and a link to the original notice -- never full tender documents, specifications, or application forms. Grants.gov is queried live per-request and is never bulk-cached or resold as a stored dataset.
live-datametadata-onlycomposition-productCyber Vulnerability Risk Search cyber-vulnerability-risk-search-v1
Search CVEs, CISA Known Exploited Vulnerabilities status, and GitHub Security Advisory package/ecosystem metadata in one call. Composes three separately licence-cleared sources: the NVD CVE API (CVSS scoring, descriptions), CVE Program data from cve.org (delivered via NVD), the CISA KEV catalog (CC0 1.0), and the GitHub Security Advisory Database's github-reviewed set (CC-BY-4.0), ingested only via a local git checkout of the public repository -- never the live GitHub Security Advisories API. Does not use OSV.dev, vendor advisory text, or any proprietary vulnerability/exploit database.
live-datametadata-onlycomposition-productDomain Trust Report domain-trust-report-v1
Single higher-value composite report for one domain: DNS resolution, TLS/SSL certificate validity and issuer, RDAP/WHOIS registration and nameservers, and email deliverability (MX/SPF/DMARC) signals, plus a derived trust score and risk band. Built entirely from already-cleared, already-live internal capabilities (domain-dns-check-v1, domain-ssl-check-v1, domain-whois-lookup-v1, email-domain-deliverability-check-v1) -- no new source, no new licence question, no proprietary reputation database.
live-datametadata-onlycomposition-productEmail Deliverability Check email-domain-deliverability-check-v1
Checks whether a domain appears technically configured for email delivery, from direct public DNS records only: MX presence, SPF presence, DMARC presence and policy, and an optional DKIM selector check. Queries DNS over HTTPS against a public resolver -- no test emails sent, no mailbox existence verification, no personal data, no leaked-email databases, no proprietary deliverability dataset.
live-datametadata-onlyprotocol-lookupProduct Safety Recall Search product-safety-recall-search-v1
Search official product safety recalls and alerts by product or brand keyword, across US FDA (food/drug) and UK OPSS (general product safety) -- the same already-cleared sources composed inside merchant-trust-check-v1, exposed here as a standalone product for use outside a merchant-domain context (e.g. checking a specific product name). EU Safety Gate non-food product alert data is licensed for inclusion (CC BY 4.0) but not yet technically integrated pending a documented access path.
live-dataofficial-sourcemetadata-onlycomposition-productGovernment Surplus Auction Search government-surplus-auction-search-v1
Search official US government surplus auction listings -- equipment, vehicles, machinery, scientific equipment, electronics, aircraft, vessels, and other surplus assets -- via the live GSA Auctions API. Returns source-linked listing metadata only: no eBay, third-party auction scrapers, or other marketplace data. GSA Auctions API responses are US federal government works, public domain under 17 U.S.C. Section 105.
live-dataofficial-sourcemetadata-onlypublic-domainMerchant Trust Check merchant-trust-check-v1
Composite trust check for a merchant domain before an agent recommends or transacts with it: live DNS/SSL/RDAP domain signals, same-origin shipping/returns/contact policy-page presence, UK Companies House registration match (GB-only), and US FDA + UK OPSS product recall/safety alert flags. Built entirely from already-cleared internal capabilities and direct, robots.txt-respecting fetches of the merchant's own public pages -- no new third-party licensed dataset. Not a fraud or compliance determination.
live-datametadata-onlycomposition-productFinancial Validation: EU VAT Number Check vat-validate-v1
Single live pass-through call to the EU Commission's VIES (VAT Information Exchange System) confirming whether an EU VAT registration number is currently valid, with registered name/address when available. Every call is a real-time confirmation only -- never a cached, stored, or aggregated result -- matching VIES's own stated purpose (real-time confirmation of VAT number validity per Council Regulation (EC) No. 904/2010) and how existing commercial VIES-based products already operate.
live-dataofficial-sourcemetadata-onlyFinancial Validation: IBAN Structural Check iban-validate-v1
Offline International Bank Account Number (IBAN) structural and checksum validation (ISO 7064 MOD 97-10) against the published SWIFT IBAN Registry per-country length table. Pure algorithmic validation of a published international standard -- no proprietary bank dataset, no network call, no third-party licence dependency.
metadata-onlyprotocol-lookupno-third-party-licenceFinancial Validation: LEI Lookup lei-lookup-v1
Live Legal Entity Identifier (LEI) lookup via GLEIF's public API: legal name, entity status, jurisdiction, and registration status. GLEIF LEI reference data is published under CC0 1.0 Universal -- commercial reuse, including paid API resale, is explicitly permitted with no attribution requirement.
live-dataofficial-sourcemetadata-onlycc0-licensedDomain Web Trust: WHOIS/RDAP Lookup domain-whois-lookup-v1
Part of the Domain Web Trust family: live domain registration lookup via RDAP (RFC 9083), useful for confirming registrar/provenance metadata before an agent interacts with a website or merchant. RDAP is the IANA-standardized, machine-readable successor to legacy WHOIS: reports registration status, registrar, and registration/expiration dates. Queried through the public rdap.org bootstrap redirector at request time -- not a scrape of any single registrar's own WHOIS server, and not a resold third-party dataset.
live-datametadata-onlyprotocol-lookupDomain Web Trust: SSL Certificate Check domain-ssl-check-v1
Part of the Domain Web Trust family: live TLS handshake against a domain's HTTPS port, useful for confirming a domain has a valid, current certificate before an agent interacts with a website or merchant. Reports certificate validity, issuer/subject, and validity window (including days until expiry). Performed via a real TLS connection at request time -- no third-party certificate-transparency dataset or resale-terms question.
live-datametadata-onlyprotocol-lookupDomain Web Trust: DNS Check domain-dns-check-v1
Part of the Domain Web Trust family: live DNS resolution check for a domain, useful for confirming a domain has valid DNS before an agent interacts with a website or merchant. Reports whether it resolves and to which IPv4/IPv6 addresses. Queries the public DNS protocol directly at request time -- no third-party dataset, no cached or scraped WHOIS/registry data, so there is no resale-terms question.
live-datametadata-onlyprotocol-lookupWeatherNext Point Forecast weathernext-point-forecast-v1
Point-location weather forecast/reanalysis lookup from Google DeepMind's WeatherNext model via Earth Engine. Every request is bounded to data at least 1 hour old -- the exact license boundary at which WeatherNext data becomes CC BY 4.0 and commercially reusable. This listing never serves data still under the real-time Terms of Use, which explicitly prohibits commercial resale.
live-dataofficial-sourcelicense-compliantmetadata-onlyLive UK Company Discovery companies-house-live-discovery-v1
Discover current UK companies through the official Companies House advanced search using bounded filters for company-name inclusion, status, type, incorporation date range, location, and five-digit SIC code. Returns at most 20 normalized company-level public-register records.
live-dataofficial-sourceadvanced-searchbounded-resultsLive UK Company Profile & Filing Status companies-house-live-profile-v1
Fetch current public-register facts for one UK company by exact company number from the official Companies House Public Data API. Returns company status and type, incorporation date, SIC codes, registered-office locality and postcode, and accounts and confirmation-statement due or overdue facts.
live-dataofficial-sourcefiling-statusprivacy-boundedLive UK Company Search companies-house-live-search-v1
Search current public UK company metadata from the official Companies House Public Data API. Returns a bounded normalized result with company identity, status, type, creation date, registered-address summary, official record link, retrieval time, and content hash.
Deterministic Product Requirements Document product-requirements-document-v2
Generate a bounded implementation-facing product requirements document from a typed brief, with stable requirement identifiers, observable acceptance criteria, explicit unknowns, and unsupported claims kept out of factual requirements.
deterministictyped-inputmodel-freeevidence-integrityLive Chain State Snapshot chain-state-snapshot-v1
Current block number and gas price for Base and Polygon mainnet, fetched live via RPC on every call. Unlike this catalogue's corpus-search listings, this makes a real outbound network call on purchase -- freshness is the product, not a stored snapshot.
NVD CVE Vulnerability Search (Full Corpus) nvd-cve-search-v1
Search the full 100,000-record NVD (NIST) CVE corpus -- description, CVSS base score, and CVSS base severity, harvested directly from the NVD API and confirmed public domain. This is the complete harvested corpus, distinct from the smaller 1,765-record cve-search-v1 listing, which draws from a five-keyword sample cross-referenced with the CISA Known Exploited Vulnerabilities list; that KEV cross-reference is not part of this corpus.
UK Property Price Search property-price-search-v1
Search recent UK property sale prices from HM Land Registry -- property type, price, town, district, and county. Published under the Open Government Licence v3.0. Address-line fields (postcode, street, house name/number) are deliberately excluded, since Land Registry's own licensing note flags those as carrying a separate Royal Mail restriction beyond the OGL grant on the transaction data itself.
SEC Filing Search sec-filing-search-v1
Search a bounded snapshot of SEC EDGAR full-text filings (10-K, 10-Q, 8-K) by keyword -- company, CIK, form type, and filing date.
FDA Product Recall Search recalls-search-v1
Search recent US FDA food and drug recall enforcement records -- product, manufacturer, reason, and risk classification. Published under CC0 1.0 Universal, explicit commercial reuse permitted. Device recalls deliberately excluded (separately licensed GMDN terminology).
World Bank Economic Indicator Search economic-indicator-search-v1
Search macroeconomic indicator values (GDP, inflation, unemployment, population) across eight major economies and multiple recent years. Published under CC BY 4.0, explicit commercial reuse permitted.
UK Procurement Notice Search procurement-search-v1
Search recent UK public-sector procurement notices from Find a Tender -- buyer, value, CPV category, and status. Published under the Open Government Licence v3.0, confirmed directly from the source's own declared package licence.
CVE Vulnerability Search cve-search-v1
Search a bounded snapshot of NVD (NIST) CVE records merged with the complete CISA Known Exploited Vulnerabilities list -- description, CVSS severity, and whether the CVE is known to be actively exploited in the wild.
OFAC Sanctions List Search ofac-sanctions-search-v1
Search the full US Treasury OFAC Specially Designated Nationals (SDN) list -- name, sanctions programme, and entity type -- for compliance/denied-party screening. Complete 19,199-entry list, not a bounded sample.
UK Company Search companies-house-search-v1
Search a bounded snapshot of the UK Companies House register -- company name, number, status, category, registered address, and SIC code. Published under the Open Government Licence v3.0, which explicitly permits commercial reuse.
NIH Research Grant Search nih-reporter-grant-search-v1
Search a bounded NIH RePORTER snapshot for federally funded biomedical research grants -- title, funded organization, administering NIH institute, award identifiers, and dates -- across every disease area and biomedical discipline, not one narrow field. Metadata only.
Commercial Use Licence Check commercial-use-licence-check-v1
Check a specific dataset, paper, repository, or model URL against the indexed open-science corpus and receive a conservative, source-linked commercial-use and redistribution status. Never infers permission from an absent or ambiguous licence -- returns unknown rather than guessing.
Crossref DOI Metadata Search crossref-research-paper-metadata-v1
Search a bounded Crossref snapshot for research-paper DOI metadata with stable DOI links, source provenance and conservative linked-work rights fields. Returns metadata only and excludes abstracts and full text.
Recent Earthquake Event Search usgs-earthquake-event-search-v1
Search a bounded, normalized snapshot of significant recent earthquake events with magnitude, time, depth, location, stable USGS links and provenance. Event-level reuse rights remain unknown because ComCat includes contributing seismic networks.
Scientific Model Search polymathica-scientific-model-search-v1
Find source-linked scientific machine-learning model records by topic. Returns metadata and provenance pointers only; model weights are not downloaded or resold, and missing licence evidence remains unknown.
Scientific Dataset Search polymathica-scientific-dataset-search-v1
Find source-linked scientific datasets by topic. Returns structured metadata pointers, declared licence fields, provenance and freshness without redistributing dataset files.
Scientific Code Search polymathica-scientific-code-search-v1
Find source-linked scientific software and repositories by topic. Returns metadata, declared licence evidence and provenance pointers without downloading or reselling repository contents.
Research Paper Search polymathica-research-paper-search-v1
Find source-linked scientific papers by topic. Returns metadata pointers, authors, dates, licence evidence when supplied by the source, and corpus provenance; it does not sell paper text or infer reuse rights.
Polymathica Archive Corpus Statistics polymathica-archive-statistics-v1
Returns reproducible aggregate statistics for the sanitized Polymathica archive census: 77,053 source rows, unique hashes, domains, file types, readiness and quarantine counts.
Polymathica Scientific Archive Search polymathica-archive-search-v1
Search a privacy-safe metadata index derived from 77,053 archived census rows and deduplicated to 23,370 unique content hashes. Includes readiness, quarantine, domain, file type, field names and provenance hashes; does not redistribute raw fields, media or third-party content.
Polymathica Archive Evidence Record polymathica-archive-record-v1
Retrieve one sanitized archive metadata record by asset id, including content hash, readiness state, field inventory summary and evidence flags.
Heated-Channel PINN GPU Job polymathica-heated-channel-job-v1
Durable asynchronous GPU-job submission. Settlement means the job was accepted and a job_id was returned; it does not mean the eventual PINN result converged or passed validation.
physicsnemogpu-backedasynchronousjob-id-returnedValidated Scientific Solver Index polymathica-validated-solver-index-v1
Search a governed snapshot of implemented, validated Polymathica PDE and scientific-computing solvers. Returns validation versions, bounded evidence locations, implementation modules and provenance without claiming a fresh solver execution.
