Coda Docs

Coda is a price settlement layer for collectible card markets. We aggregate independent market data, run a TWAP oracle, and expose the output through a developer API. No black boxes.

What we build

TWAP Oracle Time-weighted average prices across configurable windows (1-72h) with outlier filtering, floor guards, and source diversity checks.

Slab Matrix PSA / BGS / CGC / SGC grade 7-10 pricing per card, combining card-specific observations with composite market band signals.

Sparse Oracle Extended fallback with recency weighting and statistical trend fitting - tracked products always return a price.

Developer API REST JSON: per-card pricing bundles, full slab matrices, product metadata, and diagnostic meta fields.
