Macaroon grant and tender search
Search public procurement and grant opportunities in one call across UK Contracts Finder, UK Find a Tender, EU TED and US Grants.gov. POST /execute/grant-tender-opportunity-search-v1 returns source-linked metadata only: title, buyer or funder, publication date, deadline, status, region and category codes, a link to the original notice and a per-row content hash. $0.005 USDC per call on Base, no API key. Coverage is per query and is not guaranteed: a source appears in the results only when that source has a live match for your query, so one call may return rows from a single source and another may span several. Do not read a result as covering all four sources on every call. Metadata only: no tender documents, specifications or application forms are reproduced. Verify the deadline, eligibility and open or closed status against the original notice before acting.
