Search procurement opportunities API

Search UK procurement opportunities from Contracts Finder and Find a Tender with filtering by date, stage, keyword, CPV, location, and value.

The Search procurement opportunities operation is part of the Procurement Intelligence API on BRAINIAC.software. Search UK procurement opportunities from Contracts Finder and Find a Tender with filtering by date, stage, keyword, CPV, location, and value. It is exposed as POST /api/v1/procurement-intelligence/search and priced at $0.02 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: UK Contracts Finder OCDS API for search and records (contractsfinder.service.gov.uk). UK Find a Tender OCDS API for release packages and procurement processes (find-tender.service.gov.uk). TED API for EU procurement notices (api.ted.europa.eu). USAspending API for federal contract awards and recipient details (api.usaspending.gov). Limitations: UK Contracts Finder and Find a Tender APIs filter by date, stage, and identifiers only. Keyword, CPV, location, and value filtering is performed locally against returned records. TED CPV and NUTS codes are hierarchical; consult official documentation. USAspending data is limited to federal spending; state and local spending not included. Not all procurement opportunities may be available through these public APIs. Match scores are heuristic indicators and do not guarantee a chance of winning. Review each opportunity individually before submitting a bid. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Get opportunity details, Get buyer procurement history, Get awarded contracts, Match company to opportunities.
