Endpoint
GEThttps://irb-precedent-api.canvas-cart.workers.dev/doc/:id/fullWhen to prefer
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.
Side effects
- 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
