Audience: engineers and agents that need reproducible section extraction from one immutable filing.
Coverage and source scope
Retrieve a supported canonical section from one explicitly selected SEC filing. The accession number fixes the source document; preserve it with the returned source URL and section key for a reproducible citation. A missing section or unresolved accession does not establish that the underlying disclosure is absent.Canonical metadata

Reproducible filing coverage
Use this route after saving an accession number from a filing result. The accession number fixes the filing selection; optional ticker, CIK, and form are hints rather than a replacement for it.submission_file_limit bounds older-coverage resolution. Preserve provenance with the excerpt so a reader can return to the source filing.
Errors
Invalid response mode or unsupported request values return a contract-aware400. 404 section_lookup_failed means the requested accession or section could not be resolved; it is not evidence that the section contains no relevant text.

Failure posture
- keep the accessionNumber and section_key as the citation identity
- preserve source_url and requestId
- verify the accession and section key before widening a lookup
- do not silently fall back to a different filing when the requested accession fails
