How it behaves

  • Not every contract has a declared value. Measured on 4 October 2026, across all 17.39 million rows: it is missing on 10.8% of contracts (312,587 rows), and almost never on direct awards (47 out of 13.68 million) or notices (52 out of 811,033). Any total is therefore the total of the rows that DO carry a figure, not of the whole set — for tip=contracte, of nine tenths of them. Contract counts cover all rows. The val_min/val_max filters work on the RON value, so they exclude rows without one.
  • When the company is itself a contracting authority (public institution, utility), here are the contracts it awarded — who won, how much. Complementary to /firme/{cui}/achizitii, where the company is the winner.
  • A registered company that has bought nothing through SEAP returns 200 with data: null and the reason in meta.fara_date. 404 is kept only for a tax ID known to neither the trade register nor SEAP (authorities that are not companies — hospitals, town halls — are found through their contracts).
  • Each contract appears once: older publications of a contract SEAP republished and the contract value repeated on other lots are not listed (/achizitii/{id} opens them). valoare.ron is the declared value; valoare.atribuita_ron, this winner's share, is the one used in sums.
  • Sums count each contract once, with each winner's share. SEAP republishes the award notice on every update (1.19 M contract rows are republications), repeats the contract value on every lot (0.52 M) and puts the value of the WHOLE framework agreement on every winner (228,000 rows). Read raw, the 2021–2026 contracts added up to 7,059 billion lei and Farmexim to 248 billion; corrected, 1,212 billion and 14.6. Impossible values (a 125.9-billion air-traffic simulator, 1.59 billion of dairy at a child-protection directorate) are left out of sums.

What it is for

  • Analysing a public institution's spending: what it bought and from whom.
  • Data journalism on the procurement of a city hall or a hospital.
  • Finding an authority's recurring suppliers before bidding.

Response structure

FieldTypeDescription
data[].id integer
data[].an integer | null The reference year.
data[].data_contract string | null The contract date.
data[].autoritate.nume string | null The name of the contracting authority.
data[].autoritate.cui integer | null The tax ID of the contracting authority.
data[].castigator.nume string | null The name of the winning company.
data[].castigator.cui integer | null The winner's tax ID. ⚠️ SEAP puts foreign identifiers in this same field: of 179,814 distinct identifiers, 8,656 (4.8%) are not valid Romanian tax IDs — see cui_romanesc.
data[].obiect string | null The contract subject, as published.
data[].cpv string | null The CPV code of the subject.
data[].cpv_denumire string | null The official name of the CPV code, from the nomenclature. It is the fallback description when the authority wrote nothing useful in obiect — 4,582 direct purchases have the word "directa" there. null for the 11 codes (out of 8,628) missing from the CPV 2008 nomenclature.
data[].valoare.ron number | null The contract value, in RON.
data[].valoare.eur number | null The contract value, in euro.
data[].valoare.moneda_originala string | null The currency the contract was published in.
data[].valoare.atribuita_ron number | null What falls to this winner: the declared value divided by the winners of the same framework agreement; null if the declared value is impossible. All sums use it.
data[].valoare.castigatori integer How many winners share the same contract (framework agreement); usually 1.
data[].valoare.suspecta boolean true if the declared value is impossible (over 10 times the procedure estimate, or thousands of times the authority's usual contracts); still shown, but left out of sums.
data[].tip string | null The type.
data[].procedura string | null The award procedure type.
meta.paginare.pagina integer Pagina curentă.
meta.paginare.per_pagina integer Rezultate pe pagină.
meta.paginare.total integer Total rezultate.
meta.paginare.pagini integer Număr de pagini.
data[].castigator.cui_romanesc boolean true if the value validates as a Romanian tax ID, check digit included. false only means it is NOT one — usually a foreign identifier (1,257 are longer than 10 digits) or a code with a wrong check digit (7,392). We do not claim to know whose it is. Worth reading before calling /firme/{cui}: with false, the company will not be found there.

Error codes

CodeSlugWhen it occurs
401neautentificatToken missing, invalid, expired or revoked.
403feature_indisponibilThe current plan does not include the feature the route depends on.
404negasitThe tax ID [{cui}] is neither in the trade register nor a contracting authority in SEAP.
422validareThe route takes no parameters apart from lang: any other parameter returns 422 instead of being ignored.
429cota_depasitaThe plan's monthly quota has been exceeded (see Retry-After).

All errors share the same shape. eroare.cod is stable and is the value you should branch on in code — not the text in mesaj, which may change.
