Strata trading card APIs

Strata provides composable identity and market data APIs for raw cards, sealed products, and graded slabs. Identify an item through the path that matches the evidence you have, then request raw or graded markets independently. A verified provider link can connect the two markets when its printing and language are known.

The API accepts text, not image bytes. An agent or app can read a photo and send the visible name, number, set, language, and variant details. A slab lookup can resolve from supported certificates independently of raw TCGplayer coverage. ALT is the graded source; TAG cert-only lookup is not currently supported. CardLadder is link-only and is not scraped.

Use confident and candidate lists to decide whether identity is resolved. Use selectionRequired to decide whether printing, language, condition, or market needs a choice. A search score is not a calibrated probability. There is no published general accuracy measurement against a representative labeled corpus. Price data is a market observation, not authentication or an appraisal.

Create or reuse a Strata account. Registered agent platforms can connect with OAuth; scripts and other HTTP-capable agents use personal API keys. The console uses your signed-in browser session. Read the setup journey, agent operating guide, and monthly plans. Native platform availability is separate from the public API.
