APIs.io

This is the GitHub organization for APIs.io — a federated, agent-friendly directory of public-internet APIs.

The organization README shown on github.com/api-search lives in profile/README.md and documents the full public network: the path-namespaced catalogs, the search API and MCP server, the RFC 9727 api-catalog linkset, and the llms.txt agent feeds.

The whole network is served from a single origin — one S3 + CloudFront distribution on apis.io. This org holds only the build pipeline (network); each catalog is built from the upstream api-evangelist provider repos and synced into the apex site. Legacy per-subdomain hosts (providers.apis.io, …) now 301-redirect to their apex paths. The network is consumed entirely through its public infrastructure:

apis.io — the search-and-discovery hub for the whole network
Per-entity catalogs — providers, apis, schemas, collections, asyncapi, graphql, events, arazzo, json-ld, rules, vocabularies, examples
Discovery dimensions — tags, industries, regions
Agent surfaces — skills, mcp
Commercial & operational — plans, rate-limits, finops
Programmatic access — the search API and MCP server (metered & tiered; see apis.io/developer)

The site publishes llms.txt, sitemap.xml, RFC 9727 api-catalog, and (where relevant) search-index.json. Start at apis.io/.well-known/api-catalog or apis.io/llms.txt.

The catalog is licensed for public use including search indexing, AI grounding / RAG, and model training — see apis.io/terms/.
