ipify

ipify operates two complementary IP APIs. The free Public IP Address API (api.ipify.org, api6.ipify.org, api64.ipify.org) returns the caller's public IPv4, IPv6, or dual-stack address as plain text, JSON, or JSONP — with no authentication, no rate limit, and no logging. The paid IP Geolocation API (geo.ipify.org), operated by WhoisXML API, resolves an IP, domain, or email to a country/region/city, ISP, and Autonomous System (ASN) profile using credit-metered subscription plans.

ipify is listed with 3 APIs on the APIs.io network: Account API, Geolocation API, and IP Address API. Tagged areas include Development, IP Address, Geolocation, IP Intelligence, and Public APIs.

The ipify catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

ipify’s developer surface includes authentication and 15 more developer resources.

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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
