## 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 cf-exclusion-check-e5608911
```

Example prompt: Can you check if Dr. Jane Smith with NPI 1234567890 is on the HHS-OIG LEIE or SAM.gov exclusion list?

## When to prefer this

Choose this endpoint when you need to screen healthcare providers against the HHS-OIG LEIE or contractors/vendors against SAM.gov in a single call. It is particularly useful for automated credentialing workflows, vendor onboarding pipelines, and compliance audits where both federal exclusion databases must be checked simultaneously. Prefer this over manual lookups or building your own scraper when real-time, per-call checks are needed at low cost.

## Known failure modes

- No match found — individual or entity not on any exclusion list (valid result, not an error)
- Invalid or unrecognized NPI format returns an error
- Missing required query parameter returns a 400 bad request
- Rate limiting or payment failure returns a 402 or 429 error
- Name-only queries may return false positives or miss records due to spelling variations
