## 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 us-unemployment-rate-trend-brief-llm-written-7c250ff5
```

Example prompt: Give me an LLM-written brief on the recent trend in US unemployment rate — pull data from the last 30 days and summarize what's been happening.

## When to prefer this

Choose this endpoint when you need a human-readable, narrative interpretation of US unemployment trends rather than raw data points. Ideal for agent workflows that need to present economic context in plain English, generate reports, or answer natural language questions about labor market conditions. Prefer over raw data endpoints when the consumer is a person or a downstream prompt rather than a computation.

## Known failure modes

- No recent BLS data available for the requested window — brief may be empty or based on zero changes
- Invalid 'since' date-time format returns a validation error
- Payment of $0.25 USDC not completed — 402 Payment Required response
- LLM generation failure — fallback to template-based brief (reflected in generatedBy field)
- Network or upstream BLS data source unavailability

## How this service works
