## 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 fda-inspection-history-lookup-e017bbe0
```

Example prompt: Pull the FDA inspection history for Pfizer's sterile injectables facility — use FEI number 3003835695 — and show me the inspection classification trend and any Form-483 CFR citations from recent inspections for Drugs.

## When to prefer this

Use this endpoint when you need deterministic, structured FDA inspection data without LLM interpretation — ideal for compliance due diligence, supplier risk assessment, or regulatory research pipelines. Prefer this over general web search when you need machine-readable CFR citations and classification trends rather than prose summaries.

## Known failure modes

- FEI number not found in FDA records — returns empty or 404-like response
- Ambiguous firm name matches multiple manufacturers — may need to refine with state or country
- No inspection history on record for the given firm — returns empty inspections array
- Invalid product type enum value — returns validation error
- Rate limiting or payment failure via x402 protocol — returns 402 Payment Required

## How this service works

FDA inspection history for a manufacturer from public FDA records. Give an FDA FEI number or firm name and get the inspection classifications (Official, Voluntary or No Action Indicated) with the trend, plus the Form-483 observation citations with their cited CFR clause and short description. Deterministic, no LLM. Risk indicators, not legal or regulatory advice.

## Output

Returns a structured object containing the manufacturer's FDA inspection classifications (OAI, VAI, NAI) with a trend indicator, plus a list of Form-483 observation citations each with the relevant CFR clause reference and a short description of the violation — all sourced deterministically from public FDA records.
