Overview

Looks up PSA's own public Cert Verification record for one PSA-graded card by its certification number: item title, grade, label type, reverse cert/barcode flag, year, brand/title, subject, card number, category, PSA's own price estimate, and this-cert's-own population figures (population for this exact card+grade, and pop-higher). Scoped to PSA's trading-card department; a cert number issued under a different PSA division (autographs, tickets) returns a not-found error. PSA's full Population Report and Auction Prices Realized both require a PSA/Collectors account login and are not available through this endpoint. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.

Infrastructure behavior

This endpoint is executed through Crawlora's managed scraping infrastructure.

• Proxy strategy: managed automatically where needed
• Browser rendering: enabled for supported targets that require rendered HTML or JavaScript execution
• Browser cluster: supported dynamic workloads can be routed through distributed browser instances
• Retry behavior: automatic retry/fallback may be used depending on endpoint type
• Challenge handling: challenged pages or unusable upstream HTML are detected and surfaced clearly when they cannot be used
• Billing: credits are charged only for successful 2xx responses
• Observability: responses include request context where available

Response behavior

- `psa_estimate`, `psa_population`, `psa_population_url` and `psa_pop_higher` are omitted when PSA shows no figure for a given field on this cert (e.g. an ungraded/authentic-only item carries no PSA Estimate). - `psa_population_url` is PSA's own Population Report deep link for this card+grade, informational only — following it requires a Collectors account login. - `label_type` is empty when the cert carries PSA's standard label (no special label variant like Fugitive Ink or a Black Label-style qualifier). - A cert number PSA cannot resolve (invalid, or issued under a non-trading-card department) returns `404`. Example response: ```json { "code": 200, "msg": "OK", "data": { "cert_number": "125866845", "title": "2003 POKEMON SKYRIDGE #146 CHARIZARD-HOLO", "item_grade": "GEM MT 10", "label_type": "w/ Fugitive Ink Technology", "reverse_cert_barcode": true, "year": "2003", "brand_title": "POKEMON SKYRIDGE", "subject": "CHARIZARD-HOLO", "card_number": "146", "category": "TCG Cards", "psa_estimate": "$135,624.00", "psa_population": 248, "psa_population_url": "https://www.psacard.com/pop/tcg-cards/2003/pokemon-skyridge/62300", "psa_pop_higher": 0, "set_registry_note": "This cert does not appear in any sets.", "source_url": "https://www.psacard.com/cert/125866845/psa" } } ```

Error behavior

Crawlora does not silently return bad data when the upstream page cannot be used.

When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
