}Get the Federal Register documents behind a CFR section
Federal Register documents linked to one CFR section, from two signals.
Cost: 2 credits. Not-found and failed lookups are not charged. An act_id sent as a
citation (21 CFR 314.50) instead of a CFR act id adds the 2-credit /resolve fee, kept when the
citation does not resolve.
printed_note: the section’s printed source note cites 83 FR 1234, and a Federal Register rule
of the same CFR title and part spans that page of that volume and was published on the date printed.
Pre-1994 citations (legacyPrintedCitations) are kept as text and never resolved. date_join: a rule referencing the section’s
CFR title and part took effect (or was published) on a date eCFR records as an amendment of this
section. matchBasis says which; quality is verified only when both agree and candidate
otherwise. Each eCFR version row in versions gets a tier: confirmed, candidate (one date match), ambiguous (two or more documents, none picked), unmatched (searched, found nothing) or not_searched (older than the date-join window, never looked at). A document found only in the printed note, with no version row meeting its dates, is candidate in both quality and tier. Corrections are attached to their parent in corrections. A candidate is a lead, not a finding: a rule that touches the part on the same day as
an amendment may not be the one that amended this section. matchReason says so on a candidate
that matched on title, part and date only and does not name the section.
A printed note can be stale. noteIsStale is true when eCFR records an amendment later than
the newest dated citation the note prints. Newer documents then appear only as date_join
candidates. unresolvedCitations lists printed citations we could not match to a document;
that is absence in our corpus, never proof the citation is wrong. Read coverage.

}Authorizations
ApiKeyAuthApiKeyHeader
Headers
Optional. 16 to 255 visible ASCII characters (a UUIDv4 works). Repeating the same request with the same key replays the original 2xx response for 24 hours without charging again. The same key on a different request is rejected. With the account's cacheQueryDerivedData retention setting off, no body is stored and a retry answers 409 idempotency_replay_unavailable, still without a second charge.
Required string length:
16 - 255Pattern:
^[\x21-\x7e]+$Example:
"3f9c2a1e-7b44-4d0a-9c1e-5a6b7c8d9e0f"
Path Parameters
Section identifier, e.g. USC_T42_C21_S1983 (42 U.S.C. § 1983). Take it from a /us/statutes/search, /resolve or /divisions result; do not assemble one. A citation such as 42 USC 1983 also works and adds the /resolve price (see GET /us/statutes/section/{actId}). State session laws (SSL_ ids) are read at /us/session-laws/{sessionLawId}.
Required string length:
3 - 200Example:
"CFR_T21_P314_S314_50"
Response
The Federal Register documents that touch the section.
