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 is listed with 2 APIs on the APIs.io network, including REST API, and 1 more. Tagged areas include Geocoding, IP Geolocation, Location, Threat Intelligence, and Networking.

IPstack’s developer surface includes engineering blog, authentication, pricing, signup flow, support, and 25 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 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/.
