## 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-federal-reserve-event-calendar-3a4aaf94
```

Example prompt: Can you pull up the Federal Reserve event calendar for the next 30 days and show me which Fed decisions are coming up with their current market probabilities?

## When to prefer this

Use this endpoint when you specifically need Federal Reserve policy-related prediction market events and probabilities without having to filter a broader calendar. It is the fastest single call for Fed-specific forward market data. Prefer this over the general /v1/calendar endpoint when your use case is focused on monetary policy, FOMC decisions, or Fed rate movements, and you want clean, pre-filtered results.

## Known failure modes

- days parameter out of range (must be 1–90) returns a validation error
- No Fed events found in the requested window returns an empty events array
- Invalid category enum value returns a bad request error
- Payment not fulfilled (x402 payment required error if USDC payment fails)
- Service unavailability returns a 5xx error

## How this service works

Upcoming Federal Reserve event resolutions — Upcoming Federal Reserve market resolutions in date order with current blended probabilities — the forward calendar of Federal Reserve events an agent can position around. Same shape as /v1/calendar, pre-filtered to Federal Reserve markets.

## Output

Returns an array of upcoming Federal Reserve market events, each containing a slug identifier, the resolution question text, a resolution date, the current blended probability (0–1), and a category label — sorted chronologically. Also includes response metadata.
