APIs.io
APIs.io is an open-source API search engine and federated discovery network built on the APIs.json specification. It indexes API providers and their individual APIs across the public internet along with the machine-readable artifacts they publish — OpenAPI, AsyncAPI, GraphQL, Arazzo workflows, Postman collections, JSON Schema, JSON-LD contexts, Spectral rulesets, vocabularies, OAuth scopes, plans, rate limits and FinOps profiles — and lets developers and agents search that catalog by keyword, capability, tag, industry, region, artifact type and quality band. As of August 2026 the network published roughly 26,414 providers, 109,100 APIs and 120,595 schemas across 71 industries and 77 curated areas. Every provider is scored with the Kin Score, a 0–100 composite across six weighted facets plus a standalone agent-readiness score. The same read-only OpenAPI 3.1 contract powers three surfaces — a REST API at https://apis.io/api/v1, a Streamable-HTTP MCP server at https://apis.io/mcp, and a set of published Agent Skills — alongside an RFC 9727 api-catalog linkset, an llms.txt and an APIs.json self-description. It is maintained by API Evangelist and serves both API producers submitting profiles and API consumers discovering APIs.
APIs.io publishes 21 API contracts indexed on the APIs.io network, including Submit API, Areas API, Artifact Types API, and 18 more. Tagged areas include API Aggregation, API Directory, API Discovery, API Indexing, and API Rating.
The APIs.io catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 2 Spectral governance rulesets.
APIs.io’s developer surface includes authentication, engineering blog, getting-started guide, changelog, release notes, support, sandbox, and 64 more developer resources.

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.
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.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons ; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
