IPregistry

IPregistry provides a fast, reliable IP geolocation and threat intelligence REST API for looking up information associated with IPv4 or IPv6 addresses and Autonomous Systems (AS). The API returns location data, connection details, company and carrier information, time zone, currency, and comprehensive security threat assessments from over 220 OSINT threat feeds. It supports single and batch IP lookups, user-agent parsing, ASN queries, and optional EU-region routing for data residency compliance. All lookups are authenticated via API key and billed against prepaid credits that never expire.

IPregistry is listed with 1 API on the APIs.io network: IP Geolocation and Threat Intelligence API. Tagged areas include IP Geolocation, Threat Intelligence, IP Address, ASN, and Carrier.

The IPregistry catalog on APIs.io includes 1 JSON-LD context.

IPregistry’s developer surface includes documentation, engineering blog, pricing, changelog, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/ipregistry/apis.yml: open an issue on github.com/api-evangelist/ipregistry to ask a question or point us at an artifact you publish.
