⛔ RETIRED 2026-08-22 — THIS ENDPOINT NOW RETURNS 410 corpus_retired. The US court-opinion corpus is no longer served; see https://www.courtlistener.com. Nothing is charged against your record budget for this path. Original description kept verbatim below.

─────────────────────────────────────────────────────────────

The complete record for one CourtListener cluster id — the cluster_id field of any list result. Provenance (absolute_url, source_authority, bulk_edition, retrieved_at) is never withheld at any tier: the link to the decision is how you check our work, and withholding it to build an upsell would mean selling an unverifiable claim.

The record identifies the decision; it does not contain it. meta.corpus.full_text_at points at the opinion itself.

To fetch many at once use /us-law/opinions?cluster_id=1,2,3 (up to 100).
