## 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`):

```

Example prompt: Can you pull up the daily price history for the token with ID 'bitcoin' over the last month, with a fidelity of 30 data points?

## When to prefer this

Use this endpoint when you need historical price data for a cryptocurrency token and want flexible interval and fidelity control, no API key signup, and pay-per-call USDC pricing. Ideal for AI agents that need on-demand, ground-truth crypto price history without subscription overhead.

## Known failure modes

- Invalid or unknown tokenId returns an error or empty result
- Fidelity value out of range (1-1440) causes a validation error
- Unsupported interval value causes a schema validation error
- Token with no historical data returns empty series
- Network or payment failure returns HTTP 402 or 5xx error

## How this service works

Time-series price (implied-probability) history for a Polymarket outcome token. Pass the CLOB token id and an interval (1h, 6h, 1d, 1w, 1m, max). Returns timestamped price points — for charting how a market's odds moved. Read-only from Polymarket's CLOB.

## Output

Returns a time-series of historical price data for the specified cryptocurrency token, with data points sampled at the requested interval (e.g. hourly, daily, weekly) and fidelity level (number of data points up to 1440).
