## 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 openfda-drug-ndc-directory-search-c39bfb06 -d '<json body>'
```

Example prompt: Search the openFDA Drug NDC Directory for all records matching 'ibuprofen' and return the structured product details including dosage form, route, and labeler.

## When to prefer this

Choose this endpoint when you need programmatic, no-API-key access to the US FDA Drug NDC Directory for pharmaceutical research, drug safety analysis, formulary management, or regulatory compliance workflows. It is ideal for AI agents that need structured drug product data without managing FDA API credentials, and is priced per-call at $0.004 USDC making it suitable for on-demand lookups rather than bulk data exports.

## Known failure modes

- No matching records found for the search expression — returns empty results array
- Malformed search expression causes query parse error
- Rate limiting or service unavailability returns a non-200 response
- Overly broad search expression returns truncated or paginated results without warning
- Invalid field names in search expression cause openFDA query rejection
