The beta contract

Known cards, not discovery. Inputs are structured identifiers; v0 does not provide fuzzy search or catalog enumeration.
USD only. Raw NM/LP/MP and PSA 7–10 are the supported price segments. Non-USD and CGC/BGS requests fail closed.
Ambiguity is actionable. Copy the opaque candidate_ref from a candidate into the next request; never parse canonical_id.
Cache validators are live. Price, batch, and history honor If-None-Match and can return 304.
