Capabilities

What the catalog's APIs let a business DO — top-level capabilities across every industry, each with how many providers reach it. The entry point for "what can I actually build from this catalog", as opposed to "who is in it".

A capability's definition, the sub-capabilities under it, the external authorities it cites, and which providers reach it with their ratings. Accepts a slug or a BC id.

Every edge landing on a capability: the provider, the tag, the exact OpenAPI file, a calibrated confidence, and THE QUOTED FRAGMENT OF THE PROVIDER'S OWN CONTRACT that justifies the claim. Only edges at confidence >= 0.7 whose evidence was found verbatim in the source are published, so an edge here is checkable rather than asserted. This is what you cite when someone asks "says who?".

One provider's published APIs rolled up by capability, with the tag-level evidence under each. Answers "what is this vendor actually for" from its own contracts rather than its marketing. NOT /providers/{slug}/capabilities, which is artifact counts and agent-readiness dimensions and is free — the names predate this section.
