Macaroon Network · Execute Grant Tender Opportunity Search V1
api.macaroonnetwork.com
Search live UK/EU public procurement tenders and US federal grant opportunities in one call: UK Contracts Finder, UK Find a Tender Service, EU TED (Tenders Electronic Daily), and Grants.gov. Returns source-linked metadata only -- title, buyer/funder, deadline, value, region, category codes, and a link to the original notice -- never full tender documents, specifications, or application forms. Grants.gov is queried live per-request and is never bulk-cached or resold as a stored dataset.
