Everything the Congress of Colombia has published in its own gazette since 2000, not as a list of issues but as the documents inside them: bills as filed, the committee reports written on them, the minutes of sittings in both chambers, approved and definitive texts, conciliation reports and presidential objections — each with its full text and tied to the proyecto de ley it belongs to, so a bill can be followed through every stage of its passage. A second pair of endpoints covers the Gaceta’s issues themselves and the Diario Oficial, the gazette where Colombian law takes effect, indexed back to 1939.
The whole source, organized and ready to query: every endpoint on this page answers in milliseconds. Every response carries as_of: how current the data is. How datasets work.

Search documents

POST /co/imprenta/gaceta-documents-search/v1 Dataset One search across everything Congress has published since 2000, which no official site offers.
Returns as_of (how current the data is), the applied filters, total (matches across every page), page, per_page, total_pages, count and results[], most recently published first. Every result carries id, gaceta_id and gaceta_number (the issue it was published in), chamber, published_at, title (how the document is cited), summary (the epígrafe the Gaceta prints under it), kind, bill_number, bill_year and bill_chamber (the proyecto de ley or acto legislativo it is about, when the title names one), and official_url. kind is proyecto (a bill as filed), ponencia (a committee report on one), acta (the minutes of a sitting), texto (an approved or definitive text), conciliacion, objecion (a presidential objection), concepto, ley, or otro.
Search results do not carry the document’s text: a single acta de plenaria can run to two hundred thousand characters. Take an id to the Gaceta Document endpoint to read one in full.

One document

POST /co/imprenta/gaceta-document/v1 Dataset
Returns as_of, found, document_id and document, which carries text: the document itself, as the Gaceta published it. Every result carries id, gaceta_id and gaceta_number (the issue it was published in), chamber, published_at, title (how the document is cited), summary (the epígrafe the Gaceta prints under it), kind, bill_number, bill_year and bill_chamber (the proyecto de ley or acto legislativo it is about, when the title names one), and official_url. kind is proyecto (a bill as filed), ponencia (a committee report on one), acta (the minutes of a sitting), texto (an approved or definitive text), conciliacion, objecion (a presidential objection), concepto, ley, or otro.
A few documents are published with only their cover page as text — the substance of those is in the issue’s own edition, at the gaceta’s official_url.

​
Issues

POST /co/imprenta/gacetas-search/v1 Dataset The Gaceta’s own numbering, by chamber and date.
Returns as_of, the applied filters, total, page, per_page, total_pages, count and results[], most recent first. Each issue carries id, number and number_key, chamber, published_at, printed_date, legacy_label and official_url.
published_at is null on nine issues whose printed year cannot be a year (0009, 0200, 0209 and the like). Those issues are real and are returned; only the date is withheld, because the correct one is not knowable. Their printed_date shows what the Gaceta prints.

​
Diario Oficial

POST /co/imprenta/diarios-search/v1 Dataset Eighty-seven years of the gazette, by number and date.
Returns as_of, the applied filters, total, page, per_page, total_pages, count and results[], most recent first. Each issue carries id, number and number_key, edition, published_at and official_url.
The record reaches back to issue 23,962 of 2 January 1939, but it is uneven before 2000: seven years list no issues at all (1985, 1987, 1988, 1992, 1994, 1995 and 1998) and several others only a handful. An empty result for an old year means the Imprenta lists nothing for it, not that nothing was published.
