Mexico's official gazette by date
Open the full toolEvery regulator publishes on its own and none of them tells you
A compliance team in Colombia follows the Superintendencia Financiera, whose Circular Básica Jurídica and Circular Básica Contable y Financiera change through external circulars; the DIAN with its conceptos and oficios; the Diario Oficial and the Gaceta del Congreso printed by the Imprenta Nacional; Función Pública's Gestor Normativo; and the rulings of the Corte Constitucional and the Corte Suprema. In Mexico, the Diario Oficial de la Federación publishes dozens of notices on a typical business day, the Cámara de Diputados compiles more than 315 federal laws and more than 135 regulations, Banxico has regulated through circulars since 1969 and the CNBV's Circular Única de Bancos has accumulated more than 180 amendments. In Brazil, federal legislation comes out through the Planalto.
Croma turns each of those sources into an endpoint with date, number, type and text. The daily indexes (the DOF by date, amendments to federal laws by decree, Banxico circulars) query the official source at the moment of the request; searches over regulation and case law answer from the dataset Croma keeps current with the whole source. With that, detecting the change is comparing today's answer with yesterday's, and citing the rule is opening its record by identifier.
From the question to the JSON in three steps
- 01
Ask by date or by topic
A date for the full index of the DOF or of the amendments published that day; a text, a year, a type or a status to search laws, circulars, provisions, conceptos or rulings; a circular number or an identifier to open a specific rule.
- 02
Receive the rule with its trail
Title, type, publication date, validity status, issuer, full text when the source publishes it and the amendment history: every amending decree with its DOF date, every CNBV amending resolution, every Banxico circular that amends another.
- 03
Detect the change every day
Run today's query, compare it with yesterday's and notify the person responsible for that rule. Since the answer is JSON with documented fields, the difference is computed in your code, without reading the whole gazette every morning.
What you send and what you get
Each row is an API endpoint. The input is what your system already holds; the output, the fields the official registry returns.
Colombia: Superfinanciera, DIAN, Imprenta Nacional, Función Pública and the courts
Everything about ColombiaSixteen endpoints: the Superintendencia Financiera's regulation and doctrine, the DIAN's conceptos, the Imprenta Nacional's Diario Oficial and Gaceta del Congreso, the laws and decrees of Función Pública's Gestor Normativo with their text, and the rulings of the Corte Constitucional and the Corte Suprema de Justicia. They are queried by API, with a guide per source in the docs.

The Presidência da República publishes Brazilian federal legislation on the Planalto. Croma answers from the dataset it keeps current with the whole source: federal law search and the record of each one by its identifier, with its number and publication date. Search and record both have a free tool, and the answers keep the names of the statutes in Portuguese.

Three possible answers
- 01
Found
The record exists and arrives structured, with the fields in the table and the source that produced it.
- 02
No record
The source has nothing for that identifier. It is a definitive answer (found: false), not an error.
- 03
Pending
Slow sources return a job with a status_url to poll for the result, or deliver it to your webhook.
Where teams use it
Compliance at financial institutions
What the Superfinanciera, Banxico, the CNBV and the CNSF published, with the compiled text and the original to know what the rule said on a given date. DOF date and official PDF on every amendment.
Legal and tax teams
The DIAN's conceptos and oficios by topic and by document, Colombia's laws and decrees with their validity status, and the C, T and SU rulings of the Corte Constitucional alongside those of the Corte Suprema's chambers.
Gazette watch
The day's DOF index, with morning or evening edition, section and agency; Colombia's Diario Oficial and Gaceta del Congreso, with the documents of each gazette. Useful to know whether a decree, a NOM or a bill came out.
AI agents for legal teams
An agent connected over MCP asks what the DOF published on a date or what the latest CNBV resolution amended, and receives the official record with date and link to the PDF instead of a web summary.
Official records, with provenance
Official sources only
Every answer names the official registry that produced it. Nothing comes from purchased databases or third-party summaries.
Results that are never indexed
In the free tools the query and the result live in your browser, never in a URL. In the API: encryption in transit, access control and audit logging.
Personal data, with rules
Lookups on individuals require a legitimate purpose under each country's law: Ley 1581 in Colombia, LFPDPPP in Mexico, Ley 29733 in Peru, LGPD in Brazil. Croma delivers the record; the purpose and the legal basis are yours.
A stable contract
Every field is documented in the OpenAPI, with a 90-day deprecation policy and Deprecation and Sunset headers before anything is retired.
