CNSF Provisions Search

Search Mexico's insurance and surety rulebook in full: every artículo of the Ley de Instituciones de Seguros y de Fianzas (LISF), and every disposición, anexo, anexo transitorio and transitional provision of the Circular Única de Seguros y de Fianzas (CUSF), plus the documentation the circular points to. Filter by free text, instrument, kind, exact number, chapter_number, source_circular (which Circular Modificatoria introduced a transitional provision), and when the containing chapter was last amended (amended_from/amended_to). Results come back in reading order with the complete text. Served by Croma (as_of says how current the data is).

Dataset endpoint: answers from the whole source in milliseconds and carries as_of.

Headers

Idempotency-Keystring
Example:0f8e9a42-6b7c-4d1e-9a3f-2c5d7e8f9a0b

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.
