## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aisa-mpp-data-apis-polymarket-prices-history-f9b3ec36
```

Example prompt: Can you pull the price history for Polymarket market asset 0x1234abcd over the past week using 1-hour intervals, so I can see how the odds have moved?

## When to prefer this

Choose this endpoint when you need time-series price data for a specific Polymarket prediction market asset, especially when you require configurable time intervals (1m, 1h, 6h, 1d, 1w, max) or precise Unix timestamp filtering. Prefer this over generic financial data APIs when the target market is on Polymarket and you need prediction-market-specific probability/price tracking.

## Known failure modes

- Missing required 'market' parameter returns a validation error
- Invalid or nonexistent market asset ID returns empty history or an error
- Out-of-range or reversed startTs/endTs may return empty results
- Unsupported interval enum value triggers a validation error
- Very high fidelity over a long time range may return large payloads or be rate-limited

## How this service works

<!-- aisa-pricing:end -->

## Output

An array of historical price data points, each containing a price value (p, as a float) and a Unix timestamp (t, as a uint32), covering the requested time range and aggregation interval for the specified Polymarket market asset.
