Banxico

The chronological index of Banco de México circulares and disposiciones: 1,200+ entries back to 1969, each with its subject, whether it is still in effect, and which base circular it modifies. List by year, then open one for its consolidated text and modification chain.

Circulars

POST /mx/banxico/circulars/v1

Field	Type	Notes
`year`	string	Optional 4-digit year. Omit to list every year.
`page`	integer	1-based page number. 100 per page.

curl https://api.croma.run/mx/banxico/circulars/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "year": "2026" }'

Returns year (echo of the filter, null when listing every year), circulars, and pagination.

Field	Notes
`number`	Circular number as printed, e.g. `11/2026`, `E-126/2013`, `S/N`.
`year`	Year of issue.
`subject`	What the circular covers.
`modifies`	Base circular number when this one amends another; otherwise null.
`abrogated`	`true` when no longer in effect.
`has_detail`	Whether this entry links to a full record.

One row per index entry, so a circular that amends several base circulars appears once per base.

One circular

POST /mx/banxico/circular/v1

Field	Type	Notes
`number`	string	Required. Circular number as listed (e.g. `3/2012`). Matching is case-insensitive.

curl https://api.croma.run/mx/banxico/circular/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "number": "3/2012" }'

Returns found, number, and circular, which carries title, subject, abrogated, obligated_subjects (who it binds), compiled_pdf_url (current consolidated text, all modifications applied), original_pdf_url and original_dof_date (as first published), comparison_pdf_url (a consolidated comparison of every modification, when offered), abrogated_by (the abrogating instrument, or null while in force), official_url, and modifications: each amending circular with its circular_number, dof_date, pdf_url, and description.

Amendment circulars have no record of their own. Looking one up returns the amended base circular: the top-level number echoes what you asked for, circular.number is the base circular’s own number, and the requested número appears in its modifications list. When no entry with that number has a record at all, the lookup returns found: false.
