## 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-drug-device-search-api-x402-a686b075
```

Example prompt: Search the FDA database for 'metformin' and tell me what drugs and recalls come up.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-use access to FDA data without managing an FDA API key, especially in agent workflows requiring micropayment-gated access via x402 on Base or Solana. Prefer this over direct FDA open API calls when you need a hosted, always-on service with a simple query interface and crypto micropayment billing.

## Known failure modes

- Missing required 'q' parameter returns an error
- Empty or overly broad query may return too many or irrelevant results
- Payment failure (insufficient USDC balance or unsupported network) blocks the request with a 402 response
- FDA upstream API outage may cause delayed or failed responses
- Very specific or misspelled queries may return zero results
