AI Catalog Standard (ai-catalog.json)
The AI Catalog Standard is the data model underneath Agentic Resource Discovery — a JSON manifest a publisher hosts at /.well-known/ai-catalog.json that lists the agentic resources it offers, whatever they happen to be: MCP servers, agent cards, skills, workflows or plain HTTP APIs. It is artifact-agnostic by design, typing each entry with a media type rather than assuming a protocol, and it carries a progressive trust layer for attestations, provenance and signatures.
Also known as ai-catalog.json, AI Catalog Standard, /.well-known/ai-catalog.json.
Providers that carry AI Catalog 0
No provider in the catalog carries this standard as a tag yet. That is a statement about the catalog's tagging, not about adoption: a provider that implements AI Catalog and says so in its APIs.json profile appears here on the next build. Add or correct a listing.
Read from the API Evangelist standards directory. Provider links come from the catalog's own identity tags and are rebuilt nightly. If this page is wrong about a standard or a provider, say so.
