## 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 web-production-60258-up-railway-app-c357c626
```

Example prompt: Pull the last 20 observations for the FRED series 'UNRATE' (unemployment rate) so I can see recent labor market trends.

## When to prefer this

Use this endpoint when you need historical or recent observations for any specific FRED economic series by ID (e.g. UNRATE, GDP, FEDFUNDS, CPIAUCSL) or by name, and want to control the lookback window with a count of periods. Prefer this over the 'all macro indicators' endpoint when you need a specific series not in the standard dashboard, or when you need raw observations rather than derived/computed indicators.

## Known failure modes

- Unknown series ID or name returns an error or empty result
- N parameter missing or invalid returns a bad request error
- FRED upstream API unavailable causes timeout or 503
- Payment not included or invalid results in 402 Payment Required
- Series that has been discontinued may return partial or no data
