Slab identification

Use POST /api/v1/slabs/identify when the evidence comes from a graded slab. ALT resolves the certificate to its graded identity independently of TCGplayer coverage. A missing raw-card match does not cancel or weaken a successful slab result.

Send exactly one of cert, barcode, or labelText. Supply the grader when known. For ordinary slab lookups, set enrich:true to request the resolved slab’s graded market with the identity unless the user requests identity only; otherwise use /api/v1/graded/prices to choose markets explicitly.

Generate the operation ID once for a new lookup. On a network retry, rerun only the curl command with the same body and saved ID.

STRATA_OPERATION_ID=$(uuidgen)
curl https://stratatcg.com/connector/api/v1/slabs/identify \
  -H "Authorization: Bearer $STRATA_API_KEY" \
  -H 'Content-Type: application/json' \
  -H "Idempotency-Key: $STRATA_OPERATION_ID" \
  -d '{"cert":"149085863","grader":"PSA","enrich":true}'

A resolved response includes an ALT identityRef, the slab identity, an optional graded quote, and independent registry progress. rawMatch.status can be verified, queued, resolving, review_required, unmapped, unsupported, or unavailable. Only a verified raw link can support a raw comparison. Sports and foreign-language slabs remain identifiable and priceable even without one.

Present the slab identity and graded quote together. Include a TCGplayer link only when a verified raw mapping exists, clearly labelled as a raw reference. Display a returned slab image when available; never substitute an unverified card image. See result presentation.

If the result is not found or temporarily unavailable, preserve that distinction. A provider failure is not proof that the certificate is invalid. TAG cert-only lookup is explicitly unsupported by the current ALT source. Do not send a slab label to /api/v1/identify; that route identifies raw/sealed products from text.

cardLadderUrl, when returned, is an outbound cert-search link. Strata does not scrape CardLadder and does not claim the link is a verified item permalink. See graded prices to request additional markets and registry feedback to report a wrong mapping.
