## 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`):

## When to prefer this

Use this endpoint when you need fast, filtered access to FDA drug recall enforcement records — especially when you want to filter by specific fields like recalling firm, classification, or recall status, or when you need to scope results to a date range. Prefer this over raw FDA API access when you need normalized, agent-ready data without authentication overhead and with pay-per-call pricing via x402 on Base.

## Known failure modes

- No records found for given search term or field combination
- Invalid field enum value returns validation error
- Invalid date format for 'since' parameter (must be YYYYMMDD)
- Limit out of range (must be 1–25) returns error
- Payment failure via x402 protocol blocks the request
- Stale or missing FDA data for very recent enforcement actions
