More from Macaroon Network & similar services
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.
Macaroon Network · Execute Polymathica Transaction Intelligence V1
api.macaroonnetwork.com
Measure live, aggregate commerce activity across this marketplace's payment rails, including volume, success rates, and task-state breakdowns by rail and time window. Privacy-preserving by design: no buyer wallet, transaction hash, Lightning node id, or individual payment record is returned.
Macaroon Network · Execute Universal Macaroon Search V1
api.macaroonnetwork.com
Discover which Macaroon Network service, endpoint, or data product to call next. Searches Macaroon's own published catalogue -- title, category, description, price, and trust evidence metadata -- and returns a short, source-linked ranked list plus a safe recommended next call for each match. A thin wrapper over this registry's own existing semantic search and router infrastructure; does not execute matched services, does not call any underlying paid endpoint, and does not duplicate a matched ser
