What people ask Wappalyzer 6

The questions people put to an LLM, and the jobs they hand an agent, that Wappalyzer's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Wappalyzer Lists API List the lead lists I have created “Which lead lists have I already created?” Build a new lead list of websites by technology “How do I build a list of websites that use a particular technology?” Fetch one lead list and its status “Is my lead list ready yet?” Spend credits to finalize a ready lead list “How do I pay credits to unlock a lead list once it's ready?”

Wappalyzer Metadata API List every technology Wappalyzer can detect “Which technologies can Wappalyzer detect?” Get the profile of one technology “How widely adopted is a particular technology, and in which countries?” List all technology categories “What categories are technologies grouped into?” Get a category and the technologies in it “Which technologies belong to a specific category?”

Wappalyzer Verify API Verify an email address “Is this email address valid and deliverable?”

Wappalyzer Subdomains API Discover subdomains that serve websites “Which subdomains of a domain are serving websites?”

Wappalyzer Lookup API Look up the technologies a website uses “What technologies is a given website built with?”

Wappalyzer Basics API Check remaining API credit balance “How many Wappalyzer credits do I have left on my account?”

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0 Ask about this →
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too Ask about this →
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs Ask about this →
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's Ask about this →

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Surveys, Market Research and Experience Management	builds-on	34.9	-	-
HubSpot App Marketplace (CRM add-ons, outbound, performance marketing, chat)	builds-on	34.9	-	-
Browser Extension Stores (company-published Firefox add-ons; Chrome Web Store unreadable)	builds-on	34.9	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
