## 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-internal-revenue-bulletin-full-document-api-f3ecc093
```

Example prompt: Can you pull the complete verbatim text of IRS Revenue Ruling 2003-71 — I need the full official language, not a summary, for my tax research memo.

## When to prefer this

Use this endpoint when you need the complete, authoritative, verbatim text of a specific IRS guidance document for tax research or compliance purposes — not a summary or excerpt. Prefer this over general web search when you need the exact official language of a Revenue Ruling, Revenue Procedure, Notice, Announcement, or Treasury Decision from 2003 onward, especially when the precise wording matters for legal or tax positions.

## Known failure modes

- Invalid or unknown document ID returns an error — ID must first be obtained from GET /search
- Document predating 2003 not available in this dataset
- Malformed document ID format causes lookup failure
- Payment of $0.01 USDC required per call; missing payment results in 402 response
