}SCJN Tesis Search
Search the Mexican Supreme Court’s case law: every tesis and jurisprudencia the Semanario Judicial de la Federación has published since 1911 (300k+), each in full. Match words in the title and text (query, optional; every word must appear) and filter by binding force (tesis_type: jurisprudencia vs aislada), subject (materia), época number, year, deciding level (instance), court or chamber, how the criterion was formed (formation), publication window (published_from/published_to) and the court’s own modification date (updated_after). Newest first, pages of up to 50 full records; as_of says how current the data is. Read one by its registro digital with scjn-tesis.
Dataset endpoint: answers from the whole source in milliseconds and carries as_of.

Use Authorization: Bearer YOUR_API_KEY
Headers
Optional client-chosen key for this request (any string up to 255 characters, e.g. a UUID). Every Croma operation is an idempotent lookup: repeating a request with the same body returns the same result and creates nothing, so retrying after a timeout or network failure is always safe. The key is echoed back in the Idempotency-Key response header so you can correlate a retry with its first attempt. Each attempt that reaches the API counts against the rate limit.
