Historical order-book snapshots (time series) for one Polymarket market. Use interval to downsample and include_orderbook for the full ladder. History depth is gated by plan.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| coin | string | no | Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only. |
| cursor | string | no | Opaque pagination cursor from a previous response's pagination.next_cursor. |
| end_time | string | no | End of time as ms-epoch or ISO-8601. History is clamped to your plan's window. |
| fill | string | no | ffill returns ONE ROW PER BUCKET for the whole window, carrying the last captured book into buckets that held no capture. Each row then carries `filled` (0 = a capture, 1 = carried forward) and `as_of_ts`, the moment that book was recorded. Requires `interval`. Without it, `interval` returns only the buckets that held a capture — a short series means the market is quoted infrequently, not that data is missing. |
| include_orderbook | boolean | no | Include the full bid/ask ladder per snapshot (default top-of-book). |
| interval | string | no | Downsample bucket — 30s, 1m, 5m, 1h, up to 1d. Returns the newest book in each bucket. Omit for every recorded book change. |
| limit | integer | no | Page size (1–1000). |
| market_id | string | yes | Market id from polymarket_search_markets. |
| start_time | string | no | Start of time as ms-epoch or ISO-8601. History is clamped to your plan's window. |
