## 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 gloom-rate-path-api-78dd3208
```

Example prompt: What does the market currently imply for the Fed rate path — give me the implied rate, probability of a change, and basis-point shift for each upcoming FOMC meeting date.

## When to prefer this

Use this endpoint when you need market-implied Federal Reserve interest rate path data including probabilities, implied rates, and basis-point changes for upcoming FOMC meeting dates. Prefer this over central bank official communications when you want real-time market consensus rather than official projections.

## Known failure modes

- Invalid or missing properties parameter returns 400 with schema validation error
- No data available for the requested date range returns empty data array
- Payment not provided or insufficient returns 402 Payment Required
- Service downtime or upstream data unavailability returns 503
