Exports

Click download on a market. We build a file, the browser saves it, and a copy stays under Exports so you can get it again.

Window vs day pack

Window — one ticker: { "ticker": "KXBTC15M-…", "format": "csv" }
Day pack — series + UTC day: { "series": "KXBTC15M", "day": "2026-10-05", "format": "csv" }

format	Best for
`csv`	Excel / Google Sheets (default)
`parquet`	pandas / Polars / DuckDB
`json`	Scripts that want a single JSON document
`jsonl.gz`	Streaming pipelines

POST /api/v1/exports → id and status: pending
Poll GET /api/v1/exports/{id} until status: ready
GET /api/v1/exports/{id}/file with the same auth header — the browser saves the file

Snapshots are YES bid and YES ask over time. streams: ["l2"] is every book change, with orderbook_yes / orderbook_no columns.
