{"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. 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 a weekly-refreshed hosted mirror of official OCDS bulk 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 mirror.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 — What open-contracting procurement data Pipeworx currently holds: 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 weekly-refreshed mirror is before relying on it.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
