{"jsonrpc":"2.0","id":1,"method":"tools/list"}oc_tender_search — Search international public procurement — government tenders, contract notices, and contract awards published under the OCDS Open Contracting Data Standard. Covers 18 national and subnational publishers across developing countries and Europe: Africa (Kenya, Nigeria, Ghana, Zambia, Liberia, Rwanda, Tanzania), Latin America (Uruguay, Honduras, Guatemala, Peru, Dominican Republic, Mexico/Oaxaca), the Balkans (Albania, Kosovo, Croatia), Thailand (Bangkok), and Italy (ANAC anti-corruption authority). Free-text query matches tender title, buyer (procuring government entity), and description, and works in English even though most publishers file their text in Spanish, Albanian, Croatian, Italian or Thai: the query is searched alongside its equivalents in the language of the country you filter to, so "Ministry of Health" also finds "MINISTERIO DE SALUD". The response echoes every spelling it searched in query_match. Filter by country, status (e.g. tender, award, complete), category (works | goods | services), min_value (tender value floor), and days (recently released). Returns one row per contracting process (latest release) with buyer, value, procurement method, deadlines, and award details when present. Data is refreshed weekly from official OCDS publications (OCP Data Registry). Use oc_coverage first to see which countries have data and how fresh it is.oc_recent — Most recently published government procurement releases — new tenders and fresh contract awards across all covered OCDS publishers (Kenya, Nigeria, Ghana, Zambia, Liberia, Rwanda, Tanzania, Uruguay, Honduras, Guatemala, Peru, Dominican Republic, Mexico/Oaxaca, Albania, Kosovo, Croatia, Thailand/Bangkok, Italy), newest first. Optionally filter to one country and adjust the lookback window. The "what public tenders just came out" view over the weekly-refreshed OCP Data Registry feed.oc_process_history — Full release history for a single contracting process, looked up by its OCID (Open Contracting ID, as returned by oc_tender_search / oc_recent). Returns every OCDS release in chronological order, showing the tender → award → contract progression: planning and tender notices, deadline changes, and the eventual award with supplier and amount. Use it to trace how a specific government tender played out.oc_coverage — Which open-contracting procurement data is currently available: per-country publisher name, release and contracting-process counts, and latest-release freshness. Call this first to learn which of the 18 covered countries (Albania, Croatia, Dominican Republic, Ghana, Guatemala, Honduras, Italy, Kenya, Kosovo, Liberia, Mexico/Oaxaca, Nigeria, Peru, Rwanda, Tanzania, Thailand/Bangkok, Uruguay, Zambia) have data, how much, and how current the data is before relying on it.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
