## 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`):

zero fetch --capability fda-drug-approvals-llm-brief-33d7a38c
```

Example prompt: Give me an AI-written digest of the most notable FDA drug approvals since January 1st, 2025.

## When to prefer this

Choose this endpoint when you need a human-readable, AI-synthesized narrative summary of FDA drug approvals rather than raw structured data. Ideal for agents building health regulatory briefings, pharmaceutical newsletters, or monitoring dashboards where a concise prose digest is more useful than a list of individual approval records. Prefer over raw FDA data sources when the goal is immediate readability and editorial synthesis.

## Known failure modes

- No approvals found in the specified window — may return empty brief or basedOnChanges of 0
- Invalid date-time format for 'since' parameter — returns 400 or validation error
- Payment failure (x402) — endpoint requires $0.25 USDC per call, missing or failed payment returns 402
- Service unavailable on Railway — 502/503 if the upstream deployment is down
- LLM generation failure — may fall back to template-based generation (generatedBy: 'template')

## How this service works

An LLM-written digest of the most notable FDA drug approvals in the window.

## Output

Returns a JSON object with a 'brief' field containing an LLM-generated narrative summary of notable FDA drug approvals, a 'generatedBy' field indicating whether it was written by an LLM or template, and a 'basedOnChanges' integer showing how many approval records were used to produce the digest.
