Agentic Resource Discovery (ARD)

Agentic Resource Discovery (ARD) is a proposed open standard for the discovery layer the agentic web is missing — the step that happens before invocation, where a client asks “what is available for this task?” and gets back a ranked set of MCP servers, agents, skills, workflows and APIs it could use. Publishers describe their resources once at /.well-known/ai-catalog.json on their own domain; independent discovery services index those catalogs and expose them through a small REST interface. It deliberately does not execute anything, and it does not try to be the one registry.

Providers that carry Agentic Resource Discovery 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 Agentic Resource Discovery 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.
