GET
/describe
No authenticationA self-describing capability catalog: the filter grammar and every controlled vocabulary, so an agent can discover the query surface instead of guessing it.
Hardcoding a vendor's filter vocabulary into an agent means the agent breaks quietly whenever the vocabulary changes. /describe returns the current grammar and the valid values for every enumerated field — content types, authorities, topics, safety levels, verticals and sort orders.
It needs no authentication, so an agent can read the capability surface before it holds a key.
