## 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 oyapicks-prediction-market-probability-history-8a17608e

Example prompt: Can you pull up the probability history for the OyaPicks market on whether the Fed will cut rates in Q3 — I want to see how the odds have moved over time?

## When to prefer this

Use this endpoint when you need to understand how a prediction market's probability has evolved over time — ideal for trend analysis, charting price movement, detecting momentum shifts, or auditing a market's history. Prefer this over the movers or volume-spike endpoints when you already know the specific market you care about and want its full probability timeline rather than a ranked list.

## Known failure modes

- Market identifier not found — returns error if the specified market does not exist
- Invalid or missing market ID parameter — returns 400-level error
- Market too new — insufficient history to return meaningful time-series data
- Payment failure — x402 payment of $0.03 USDC not processed, returns 402
- Rate limiting if too many requests in a short window
