DOF

Everything published in the Diario Oficial de la Federación: decrees, law reforms, and regulator disposiciones across the morning, evening, and extraordinary editions. List a day first, then fetch the full text of any entry you care about. History reaches back to at least 1995.

Publications by date

POST /mx/dof/publications-by-date/v1

Field	Type	Notes
`date`	string	Required. Gazette date, `yyyy-mm-dd`. Back to at least 1995.

curl https://api.croma.run/mx/dof/publications-by-date/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "date": "2026-07-16" }'

Field	Notes
`date`	Echo of the requested date.
`published`	`false` on days with no gazette (weekends and holidays); `publications` is then empty.
`total`	Number of publications that day.
`publications`	List of entries (see below).

Each publication carries id, title, edition, section, page, page_end, branch (e.g. PODER EJECUTIVO), agency, has_pdf, and has_text.

has_text: true means the full text is machine-readable and worth fetching with the lookup below. Entries with has_text: false are scanned images.

POST /mx/dof/publication/v1

Field	Type	Notes
`publication_id`	string	Required. The `id` of an entry from the day listing.
`offset`	number	Optional. First character of the text to return (default 0).
`limit`	number	Optional. Characters to return, 1000 to 1000000 (default 200000).

curl https://api.croma.run/mx/dof/publication/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "publication_id": "5778302" }'

Returns found, publication_id, and publication. The publication carries the day-listing metadata (except the has_* flags), plus sub_agency, content, is_image_only, and official_url. Publications range from a few hundred characters to entire decrees, so the text comes back in ranges under content: text, offset, total_length, has_more, and next_offset. Read content.total_length for the full size, and while content.has_more is true request the next range with offset set to content.next_offset.

Scanned publications return is_image_only: true with content null. The metadata and official_url are still populated.
