Public procurement of a Portuguese company

Every week IMPIC publishes, as open data (public domain), every Portuguese public contract registered on Portal BASE since 2012 — about 170,000 to 250,000 contracts a year, thirty-nine fields each, with contract modifications and the notices of the Diário da República. This route finds a company by its NIPC, as winner and as buyer.

What the route returns

Catalogue description, exactly as agents read it:

Public-procurement record of a Portuguese company from IMPIC's Portal BASE (weekly open-data files on dados.gov.pt, public domain; every public contract since 2012): contracts WON by NIPC — buyer, subject, procedure, CPV, lots, contract, base and final prices in EUR, dates, duration, framework agreement, closure, bidder count, contract modifications — contracts ISSUED as a buyer and notices in the Diário da República; newest first, capped at 100. Winners without a published NIF are never named.

Expected identifier

Nine-digit NIPC (check digit verified; PT prefix, dots and spaces tolerated), e.g. 504904493.

A wrongly formatted identifier in the path returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

Price and billing

Price: $0.02. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

What this route does not do

Partial coverage by construction: 11.6 % of winners and 8.8 % of bidders are published without a NIF (natural persons or foreign entities) — never named, only counted; bidders are served as counts only; the portal is declarative. Zero never means “never won a contract”. Amounts in EUR as published.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
