ecfr_get_section
Retrieve the full, in-force text of a single Code of Federal Regulations (CFR) section by citation. Supports optional issue date and returns heading, full text, and eCFR URL.
Instructions
Get the FULL in-force text of ONE CFR section by citation (the companion to ecfr_search, which returns only snippets). Input titleNumber (1–50) + section (e.g. '200.1' → 2 CFR 200.1, uniform grants guidance; '1601.1' → 29 CFR labor) + optional issue date (default = the title's latest). Returns { citation, alternateReference, heading, fullText, issueDate, ecfrUrl }. ★For a FAR/DFARS clause (title 48) prefer far_clause_lookup — it adds the prescription, revision, and FAR-overhaul-risk this generic tool does not; use ecfr_get_section for the OTHER 49 titles (grants/labor/IRS/SBA/…). HONESTY: text is the eCFR's own, de-XMLed (no fabrication); a nonexistent section ⇒ not_found (never a fake/wrong section); the resolved issue date is disclosed (the title's latest is a moving target); a bad section format ⇒ invalid_input (SSRF charclass); an outage ⇒ throws. Keyless.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| date | No | Optional eCFR issue date YYYY-MM-DD; omit to use the title's LATEST issue (disclosed in _meta). | |
| section | Yes | The section citation, e.g. '200.1' (2 CFR 200.1) or '52.204-21' — the part number is the pre-dot integer. Charclass-validated (^[0-9]{1,3}\.[0-9]{1,4}(-[0-9]{1,4})?$). | |
| titleNumber | Yes | CFR title (1–50). e.g. 2 = federal financial assistance (grants), 29 = Labor, 26 = IRS. For FAR/DFARS (title 48) prefer far_clause_lookup. |
