## 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 api-lastlookdata-com-4bc1dfd4
```

Example prompt: Can you pull the last 365 days of the 10-year Treasury yield (DGS10) from FRED so I can see the full year trend?

## When to prefer this

Use this endpoint when you need a full year (365 days) of historical data for a supported FRED economic series — ideal for trend analysis, charting, backtesting, or computing year-over-year changes. Prefer the /api/series/30 or /api/series/90 endpoints when you only need recent data and want to minimize cost. Use the /api/current endpoint when only the latest single value is needed. Use /api/date when you need a point-in-time value on a specific past date.

## Known failure modes

- Missing or invalid 'id' query parameter returns an error — must be one of the 24 supported FRED series IDs
- Unsupported series ID not in the allowed enum returns a validation error
- Payment not provided or rejected causes a 402 Payment Required response
- Series with lower publication frequency (e.g. GDP, MSPUS) may return fewer than 365 actual data points since those are released quarterly or monthly
- Network timeout or upstream FRED data unavailability may cause 5xx errors
