# Get Polymarket Market Date Range

> Return the stored date range for a Polymarket market condition ID.

## Request

### Headers

<ParamField header="Authorization" type="string" required>
  Bearer token. Example: `Bearer YOUR_API_KEY`
</ParamField>

### Query Parameters

<ParamField query="condition_id" type="string" required>
  The Polymarket market condition ID. Values are accepted with or without the `0x` prefix.
</ParamField>

## Response

<ResponseField name="market_condition_id" type="string">
  The normalized Polymarket market condition ID.
</ResponseField>

<ResponseField name="has_data" type="boolean">
  Whether any stored data was found for the market.
</ResponseField>

<ResponseField name="start_date" type="string">
  Earliest stored date for this market, or `null` if none exists.
</ResponseField>

<ResponseField name="end_date" type="string">

</ResponseField>

<ResponseField name="available_date_count" type="integer">
  Number of distinct stored dates found for the market.
</ResponseField>

<Tip>
  Use this endpoint as the authoritative per-market availability check before requesting raw Polymarket data. Orderbook data exists for a subset of Polymarket markets from `2025-09-01`, but coverage is not continuous. Continuous Polymarket crypto-related market coverage begins on `2026-02-04`, and continuous coverage for all Polymarket markets begins on `2026-04-02`.
</Tip>

<Note>
  `GET /api/v1/polymarket/market/date-range` reflects stored dates in S3. It does not prove every second in that day is complete. `GET /api/v1/polymarket/market/data` still rejects dates earlier than `2026-02-08`.
</Note>
