# 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. ## Extract from a genuinely paid response Dated snapshot from 2026-09-18, truncated to one item per array. It is not live data. The full extract is served **free of charge** from [the samples surface](https://api.sirenic.eu/exemples/), and the schema from the OpenAPI document. ``` { "pays": "PT", "nipc": "504904493", "attributions": [ { "id": "12491739", "ano": 2026, "procedimento": "appel d'offres ouvert", "procedimento_source": "Concurso público", "tipo_contrato": [ "fournitures" ], "objeto": "Aquisição de equipamento informático", "adjudicante": { "nif": "501413197", "nom": "Universidade do Porto" }, "adjudicatarios": [ { "nif": "504904493", "nom": "RIS 2048 - Sistemas Informáticos e Comunicações, S.A.", "pme": true } ], "adjudicatarios_sans_nif": 0, "publie_le": "2026-01-09", "celebre_le": "2026-01-07", "preco_contratual_eur": 215012, "preco_base_eur": 220729, "prazo_dias": 365, "cpv": [ "30213100-6" ], "lotes": [ "Portáteis, computadores e outro equipamento informático" ], "concorrentes": 2, "concorrentes_sans_nif": 0, "modificacoes": [ { "data": "2026-06-01", "tipo_ato": "Acordo entre as partes", "preco_alterado_eur": 215012 } ] } ], "nombre_attributions": 1, "valeur_totale_eur": 215012, "tronque_attributions": false, "aucune_attribution": false, "contrats_emis": [], "nombre_contrats_emis": 0, "tronque_contrats_emis": false, "avis_emis": [], "nombre_avis_emis": 0, "tronque_avis_emis": false, "stock": { "depuis": "2012", "annees_chargees": [ 2026 ], "fichiers_du": "2026-09-13" } } ``` ## 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. ## Calling the route ``` # 1.

Zero never means “never won a contract”. Amounts in EUR as published. ## Neighbouring routes - `/v1/eu/entreprise/ES/{nif}/marches-publics` — $0.02 - `/v1/eu/entreprise/PL/{nip}/marches-publics` — $0.02 - `/v1/eu/entreprise/LV/{regnr}/marches-publics` — $0.02 ## 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](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) 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.
