Your API Stack

Pick the API providers that matter to you — the ones you build on, buy from, compete with, or are diligencing — and keep them in one place. APIs.io watches their Kin Score, agent readiness, and published resources, and hands the whole stack back to you as an apis.yml you can commit, share, or drop into an agent.

This stack lives in your browser, in a cookie. Nothing is sent to APIs.io and there is no account — the page stores only the provider slugs (and the score each was at when you added it) in a first-party cookie named apisio_stack. Clear your cookies, use a different browser or device, or browse privately and your stack is gone. Download the apis.yml to keep a durable copy — you can upload it here again any time.

Add a provider to your stack

Exports are APIs.json 0.21. Each provider carries its Kin Score and agent-readiness block, its published resources (OpenAPI, MCP server, agent skills, rules, plans, rate limits, scopes, security), and an include pointer to the provider's own apis.yml so a tool can pull the full record. Upload accepts anything this page exports — and any single provider's own apis.yml.
