## 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 x402-factory-com-prediction-market-calendar-e87d12cb
```

Example prompt: What prediction markets are resolving in the next 14 days in the politics category — show me each one sorted by settlement date with their current probabilities.

## When to prefer this

Use this endpoint when you need a time-ordered view of which prediction markets are settling soon and what probabilities they currently carry — ideal for agents that need to monitor market resolution timelines, brief users on upcoming events, or act on markets before they close. Prefer this over individual market lookups when you need a calendar-style sweep across multiple markets.

## Known failure modes

- Invalid days value outside 1–90 range returns validation error
- Invalid category enum value returns 400 bad request
- Payment not accepted or x402 payment failure returns 402
- No markets found for the given category or horizon returns empty list
- Upstream data source unavailable returns 503

## How this service works

Upcoming market resolutions in the next N days with current probabilities — Active markets resolving inside the horizon, sorted by resolution date with the current blended probability. An agent's event calendar: what settles soon and where it stands.

## Output

A list of active prediction markets resolving within the requested time horizon, each with its resolution date, current blended probability, and category — sorted chronologically by settlement date.
