## 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 scriptmasterlabs-fred-series-data-api-3c66b2a3
```

Example prompt: Can you pull the latest data for the FRED series CPIAUCSL — I want to see the current value, units, and frequency?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call lookup of the latest value and metadata for a specific FRED economic series without managing a FRED API key. Ideal for agents that need occasional spot checks of macroeconomic indicators (CPI, GDP, unemployment, etc.) on a usage-based cost model via x402 micropayments.

## Known failure modes

- Invalid or unknown series_id returns an error response
- Rate limiting or payment failure (x402) prevents data delivery
- FRED series may be discontinued or have no recent value
- Malformed series_id format (outside allowed pattern) rejected at input validation

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

A JSON object containing the series ID, latest value, date of the value, official title, units, frequency, data source identifier, and a product/status label confirming the data is ready.
