## 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 irs-nonprofit-tax-exempt-status-lookup-ef8b1953
```

Example prompt: Can you check whether EIN 13-1837418 is currently IRS tax-exempt, what its 501(c) subsection is, and whether it's listed in Publication 78 as eligible to receive deductible contributions?

## When to prefer this

Use this endpoint when you need authoritative, IRS-sourced verification of a US nonprofit's tax-exempt status by EIN — especially for donor due diligence, grant compliance, payroll platform onboarding, or any workflow requiring confirmation of 501(c) classification, Publication 78 listing, or revocation history. Prefer this over general web searches or third-party charity databases when regulatory accuracy and official IRS data are required.

## Known failure modes

- EIN not found in IRS database — organization may not exist or may never have been tax-exempt
- Invalid EIN format — must be exactly 9 digits
- Organization was revoked and not reinstated — status returned as not currently exempt
- Network timeout or IRS data source unavailability
- Rate limit or payment failure for the x402 micropayment

## How this service works

Crisp authoritative IRS tax-exempt status for a US nonprofit by EIN: whether it is currently tax-exempt, listed in Publication 78 as able to receive deductible contributions with the eligibility code, whether its status was automatically revoked with the revocation and reinstatement dates, and its 501(c) subsection.

## Output

Returns a structured record indicating whether the organization is currently tax-exempt, its 501(c) subsection code, whether it appears in IRS Publication 78 (and the associated deductibility eligibility code), and if applicable, the dates of any automatic revocation and subsequent reinstatement.
