APIs.io Search API

The APIs.io API is a read-only discovery API over the APIs.io catalog. It lets developers and AI agents search and browse APIs, providers, tags, industries, and regions, and select published artifacts (OpenAPI, AsyncAPI, Postman, Arazzo, JSON Schema, JSON-LD, GraphQL, rules, and more), with provider ratings and a unified /search endpoint. Served at https://apis.io/api/v1; the same OpenAPI contract powers the APIs.io MCP server at https://apis.io/mcp.
