Search Greece's official public procurement registry — ΚΗΜΔΗΣ (Central Electronic Registry of Public Contracts) — and get back clean, structured JSON: contracts, tender notices, awards, payment orders and purchase requests, with amounts, named contractors and their VAT numbers, CPV codes and document links.

Built on the official ΚΗΜΔΗΣ OpenData API. No HTML scraping, no login, no API key.

Why this and not the transparency portal

Greece publishes public spending in two places. ΚΗΜΔΗΣ is the procurement-specific one, and for procurement it is far richer than the general transparency portal (Διαύγεια):

	Διαύγεια	ΚΗΜΔΗΣ (this Actor)
Filter by amount	after fetching	the registry filters it
Find everything awarded to one company	not possible	search by contractor VAT
Filter by CPV code	no	yes
Contractor name & VAT	often missing	on virtually every contract
Record types	one	five
Links between related acts	no	notice → award → contract → payments

If you need the whole of Greek government decision-making rather than procurement, use the companion Actor Greek Government Decisions Search (Diavgeia). Many records here carry a diavgeiaAda, linking the two.

Input

Field	Type	Description
recordTypes	array	contracts, notices, auctions, payments, requests. Default contracts.
keywords	array of strings	Words to match in the record title. Each entry is searched separately and merged.
organization	string	Contracting authority: name, public-body id, or 9-digit VAT number.
contractorVat	string	Return only records awarded to this company VAT number (ΑΦΜ).
contractorName	string	Return only records whose contractor name matches.
cpvCodes	array of strings	CPV codes, e.g. 30200000-1.
dateFrom / dateTo	string	YYYY-MM-DD. Registry submission date — see the note below.
minAmount / maxAmount	integer	Contract value in EUR, filtered by the registry itself.
maxResults	integer	Maximum records to return. Default 100.

All fields are optional. With no input you get the last 6 months of contracts, capped at maxResults.

Example input

Every IT contract over €50,000 awarded by the City of Athens in the first half of 2025:

{
  "recordTypes": ["contracts"],
  "organization": "Δήμος Αθηναίων",
  "cpvCodes": ["30200000-1"],
  "minAmount": 50000,
  "dateFrom": "2025-01-01",
  "dateTo": "2025-06-30"
}

Everything one company has won across all of Greek government:

{
  "recordTypes": ["contracts", "auctions", "payments"],
  "contractorVat": "800606208",
  "dateFrom": "2025-01-01",
  "dateTo": "2025-12-31"

adam is the ΑΔΑΜ, the unique identifier of every act registered in ΚΗΜΔΗΣ.

relatedAdam is the useful part. Greek procurement runs as a chain — tender notice → award → contract → payment orders — and each record names the others by ΑΔΑΜ. The contract above links to its award and to 26 separate payment orders, so you can follow what was actually paid against a signed contract, not just what was promised.

Three things to know

1. Dates are submission dates, not signature dates. dateFrom/dateTo filter the day an act was published to the registry, which is routinely weeks after the contract was signed. In a sample filtered to 10–12 June, contracts signed as far back as 21 May appeared. Every record carries both submissionDate and signedDate, so filter on the former and read the latter.

2. Search contractors by VAT, not by name. Greek company names are typed inconsistently by each authority — the same supplier appeared as "ΝΤΑΛΑΕΚ ΜΟΝ. ΙΚΕ", "ΝΤΑΛΑΕΚ ΜΟΝΟΠΡΟΣΩΠΗ ΙΚΕ" and even "ΝΤΑΛΑΕΧ" across eight contracts. The VAT number is the only reliable key.

3. Volume costs requests. ΚΗΜΔΗΣ returns a fixed 50 records per API call and offers no way to raise it, so 1,000 results means 20 calls. Set maxResults to what you actually need.

• Greek Public Contractor Profile — take a contractor VAT number from these results and get that company's whole record with the Greek state: total won, which authorities award it, direct-award share, CPV mix and yearly trend.
• Greek Public Tenders Monitor & Alerts — the same search, running on a schedule across both registries. It remembers what it already reported, so you are told only about genuinely new tenders and contracts, by email or webhook. Use it when you want to be notified rather than to go looking.
• Greek Government Decisions Search (Diavgeia) — every kind of Greek government decision, not just procurement: appointments, circulars, grants, regulatory acts and more.

Limitations & disclaimer

• Data comes from the official ΚΗΜΔΗΣ OpenData API as published. Contracting authorities upload their own acts, so completeness and accuracy are theirs. No guarantee of completeness is given or implied.
• The registry is refreshed by an automatic daily process, so very recent acts may not appear yet.
• Tender notices and purchase requests have no contractor yet, so contractor filters do not apply to them; the run log says so when they are ignored.
• Contracting-authority names are resolved against the official Greek public-body catalogue published by Διαύγεια, which uses the same organization identifiers as ΚΗΜΔΗΣ.
• This tool searches contracts and public bodies, not individuals. Contractor records are companies and their VAT numbers; some sole traders appear as named persons because Greek procurement law requires publication. Handle any personal data in results in line with the GDPR.
• Source data is licensed CC BY 4.0 by the Greek Ministry of Digital Governance. Not affiliated with or endorsed by the Ministry.

Τι κάνει

Ψάχνει το ΚΗΜΔΗΣ (Κεντρικό Ηλεκτρονικό Μητρώο Δημοσίων Συμβάσεων) και επιστρέφει δομημένα δεδομένα: συμβάσεις, προκηρύξεις, αναθέσεις, εντολές πληρωμής και αιτήματα — με ποσά, ανάδοχο και ΑΦΜ αναδόχου, κωδικούς CPV και σύνδεσμο στο έγγραφο.

Στηρίζεται στο επίσημο OpenData API — χωρίς scraping, χωρίς κλειδί.

Γιατί είναι καλύτερο από τη Διαύγεια για διαγωνισμούς

Το ΚΗΜΔΗΣ φιλτράρει ποσό από τον ίδιο τον server, ψάχνει ανάδοχο με ΑΦΜ και υποστηρίζει CPV — τρία πράγματα που η Διαύγεια δεν κάνει. Και ο ανάδοχος υπάρχει σχεδόν πάντα, ενώ στη Διαύγεια λείπει συχνά.

Τρία πράγματα που πρέπει να ξέρεις

1. Οι ημερομηνίες είναι ανάρτησης, όχι υπογραφής. Το φίλτρο πιάνει την ημέρα που αναρτήθηκε η πράξη στο μητρώο, που είναι συχνά εβδομάδες μετά την υπογραφή. Κάθε εγγραφή έχει και τα δύο πεδία.
2. Ψάξε ανάδοχο με ΑΦΜ, όχι με επωνυμία. Η ίδια εταιρεία γράφεται διαφορετικά από κάθε φορέα — σε οκτώ συμβάσεις εμφανίστηκε ως «ΝΤΑΛΑΕΚ ΜΟΝ. ΙΚΕ», «ΝΤΑΛΑΕΚ ΜΟΝΟΠΡΟΣΩΠΗ ΙΚΕ» και «ΝΤΑΛΑΕΧ». Μόνο το ΑΦΜ είναι αξιόπιστο.
3. Το relatedAdam συνδέει την αλυσίδα: προκήρυξη → ανάθεση → σύμβαση → εντολές πληρωμής. Βλέπεις τι πληρώθηκε τελικά, όχι μόνο τι υπογράφηκε.

Νομικά

Τα δεδομένα προέρχονται από το επίσημο API του ΚΗΜΔΗΣ και παρέχονται όπως έχουν αναρτηθεί από τις αναθέτουσες αρχές — χωρίς εγγύηση πληρότητας. Άδεια πηγής: CC BY 4.0. Δεν συνδέεται με το Υπουργείο Ψηφιακής Διακυβέρνησης.
