About

The APIs.io network indexes thousands of APIs, providers, capabilities, and related resources across a set of specialized subdomains. Each subdomain publishes a search-index.json — a compact JSON array optimized for client-side search with MiniSearch.

This developer portal documents each feed as an API, describes the response schema, and provides code examples for consuming the feeds in JavaScript, Python, and other languages.

All feeds are:

Public — no API key or registration required
Static — served directly from GitHub Pages via Cloudflare
CORS-enabled — consumable directly from the browser
RFC 9727 compatible — each subdomain publishes /.well-known/api-catalog

The portal itself is open source at github.com/api-search/developer-portal.
