## 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 nih-nlm-rxterms-drug-name-search-789cf873 -d '<json body>'
```

Example prompt: Search the NIH NLM RxTerms database for prescribable drug names matching 'metformin' and give me the drug codes and display names.

## When to prefer this

Choose this endpoint when you need keyless, no-registration access to NIH NLM RxTerms drug name data for clinical coding, EHR autocomplete, or prescription validation workflows. Prefer it over direct NIH API calls when operating in an agent or microservice context with x402 micropayment support and no API key management overhead.

## Known failure modes

- No matches found for an obscure or misspelled drug term — returns empty result set
- Upstream NIH NLM Clinical Tables service unavailable — may return gateway error
- Invalid or missing input body — returns 400-level error
- Payment not completed via x402 — returns 402 Payment Required
