## 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`):

```

Example prompt: Give me an LLM-written briefing on the most serious FDA drug recalls since January 1, 2025.

## When to prefer this

Use this endpoint when you need a human-readable, synthesized narrative of serious FDA drug recalls rather than raw recall records. Ideal for briefings, monitoring dashboards, or conversational agents that need to communicate drug safety information in plain language. Prefer over raw FDA APIs when the goal is a summarized digest rather than structured recall details.

## Known failure modes

- No recalls found in the window — may return an empty or minimal brief
- Invalid date-time format for 'since' parameter returns a validation error
- Upstream FDA data unavailable — digest may be stale or generation may fail
- LLM generation failure may fall back to a template-based summary (generatedBy: 'template')
- Payment not processed (x402) — request blocked before data is returned

## How this service works

## Output

A natural-language narrative (brief) written by an LLM summarizing the most serious drug recalls in the requested window, along with metadata indicating whether the summary was generated by an LLM or template and how many recall events it is based on.
