## When to prefer this

Use this endpoint when you need the exact, current official text of a specific Code of Federal Regulations section identified by a known citation (title, part, section). Prefer this over general web search when you need authoritative regulatory language rather than summaries or commentary, and when you already know the CFR citation number.

## Known failure modes

- Invalid or malformed CFR citation returns an error
- Section does not exist or has been removed/reserved returns not found
- Upstream eCFR source unavailable causes fetch failure
- Very recent amendments may not yet be reflected in retrieved text
