IPstack

IPstack is an IP geolocation API from APILayer, an Idera, Inc. brand. A single GET request against api.ipstack.com resolves an IPv4 or IPv6 address into more than 100 fields — country, region and city, latitude and longitude, time zone, local currency, ISP, ASN and connection type — plus an optional security module that flags proxies, VPNs, Tor exit nodes and known threat actors. Standard, bulk (up to 50 addresses) and requester lookups are offered in JSON, XML and JSONP. The same data is exposed to agents through APILayer's hosted MCP server at mcp.apilayer.com, which publishes RFC 9728 protected-resource metadata and an OAuth authorization server at auth.apilayer.com.

IPstack publishes 1 API on the APIs.io network: REST API. Tagged areas include Geocoding, IP Geolocation, Location, Threat Intelligence, and Networking.

IPstack’s developer surface includes engineering blog, authentication, pricing, signup flow, support, and 19 more developer resources.

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.

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 github.com/api-evangelist/ipstack: open an issue to ask a question, or submit a pull request to add artifacts.
