  not_exercised:
  - POST /api/agents/register creates an account and issues a key, so it was described from the docs only.
  - A successful POST /api/query consumes a free-tier lookup and runs a live eBay search; the 200 shape is the provider's captured live response of 27 Jul 2026 reproduced verbatim from the docs.
