Private controlled beta
Known-card USD pricing API v0
Bring a TCG, set, and collector number. Receive deterministic identity resolution, printing candidates, USD price snapshots, batch results, or aggregate history.
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_reffrom a candidate into the next request; never parsecanonical_id. - Cache validators are live. Price, batch, and history honor
If-None-Matchand can return304.
