## 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 osf-healthcare-records-search-17b62423
```

Example prompt: Can you look up the NPI record and any FDA recall history for semaglutide — I need the RxCUI identifier and provenance links from the CMS and openFDA databases?

## When to prefer this

Use this endpoint when you need to search across US healthcare public datasets — verifying a provider NPI, resolving a drug name to its RxCUI, checking FDA recall enforcement history, or finding clinical trial status — especially when you need provenance-stamped results from authoritative US government sources like CMS, NLM, ClinicalTrials.gov, or openFDA in a single call.

## Known failure modes

- No matches found for the given query keyword — returns empty results array
- Query too vague returns too many low-relevance results
- NPI or NCT ID not found in current CMS or ClinicalTrials.gov snapshot
- openFDA recall records may lag the official FDA enforcement database
- Rate limiting or payment failure returns 402 or 429 error
- Ambiguous drug name resolves to multiple RxCUI candidates

## How this service works

Search US healthcare data by keyword: CMS NPPES NPI provider records, NLM RxNorm drug concepts, ClinicalTrials.gov studies, and FDA recall enforcement for drugs, devices, and food (openFDA, full history since 2004). Verify a provider or NPI, resolve a drug to its RxCUI, check trial status, or check a product for recalls. Returns identifiers, key facts, and a provenance URL per match.

## Output

Returns a list of matched records per data source (CMS NPPES provider records, RxNorm drug concepts, ClinicalTrials.gov studies, FDA recall/enforcement records), each with key identifiers, key facts, and a provenance URL linking back to the authoritative source.
