# Get Lighter L3 orderbook history JSON Schema

> Get Lighter L3 orderbook history JSON Schema contract. Includes parameters, response shapes, examples, and implementation notes from the 0xArchive contract.

Source OpenAPI: 0xArchive API 1.8.0; 227 paths; 217 component schemas.

Get historical Lighter L3 order-level snapshots with price, remaining size, order\_index, and owner\_account\_index. The public checkpoint-history response is an array of snapshots; each snapshot returns up to 250 resting orders per side. Optional `granularity` selects checkpoint, 30s, 10s, 1s, or tick resolution (checkpoint default); optional `account` filters by numeric account index. Data available from March 2026.
