# Sirenic or API Entreprise (DINUM)

This comparison has a clear answer, and it does not favour us. If you are a public administration, use API Entreprise. It is free, broader than us on employer and tax obligations, and grants access to non-public data no private player is entitled to. We cannot compete on any of those three.

## What API Entreprise (DINUM) does better than us

Let us start there, because it is what decides half the cases — and because a comparison where the competitor never wins anything does not deserve to be read.

- If you are a public administration, **stop here and use API Entreprise**: tax and social-security certificates, non-public data, free of charge. We cannot compete on any of those three, and we do not claim to.
- Their data scope **exceeds ours** on everything touching public procurement eligibility and employer obligations.

## When to use API Entreprise

- You are a **public administrative entity** — or a software vendor serving administrations. That is their stated eligibility condition: only administrative entities are eligible.
- You need **tax and social-security certificates**, or non-public data. Off-limits to the private sector, therefore unavailable from us at any price.
- You can wait for the **authorisation**: it goes through an application reviewed by their legal team, with no stated lead time.

## API Entreprise (DINUM): what we found

Surveyed on 2026-08-19, source: [https://entreprise.api.gouv.fr/](https://entreprise.api.gouv.fr/). Every line is verifiable by you, at the same address.

- “**Seules les entités administratives sont éligibles**” (only administrative entities are eligible) — software vendors serving administrations may also qualify.
- Access goes through a **DataPass authorisation**, reviewed by their legal team. No lead time is stated on the page.
- The service aggregates more than 20 bodies (INSEE, DGFIP, URSSAF, INPI, Banque de France…) and grants access to certificates the private sector cannot obtain.
- Non-administrative applicants are **redirected to the public company directory**, which is a lookup service, not an API contract.

## What Sirenic does differently

- **Pay per call, no account, no key.** A `402` call, a settlement in USDC or EURC, the response. No sign-up, no contract, no IP address to declare, no expiring credits. 79 routes are reachable that way.
- **An upstream outage closes the route.** We answer `503` and cancel the payment rather than serve a degraded response. A registry snapshot that is too old also closes the route that reads it, instead of selling dead data.
- **Ed25519-signed responses.** You can prove months later what was served to you, and when.
- **Per-block provenance.** Each block of a file declares its official registry and as-of date, rather than a blanket “official sources” claim.
- **You are not eligible.** That is the only reason that really counts: a private company is redirected to the public directory, which is a lookup service, not an API contract.
- **No authorisation to obtain.** You call and you pay. Time to access is the time to settle, not the time to be approved.
- **A different scope, not a competing one**: international sanctions, public contracts and their expiries, European registers, invoicing checks, default-risk scoring, sector statistics.

## How this comparison is built

Every fact carries its **survey date** and its **source address**, so that you can contradict it. Nothing is extrapolated: what we could not survey is marked as not surveyed rather than guessed. And every page names what the compared service does better than us — a comparison without that section is not a comparison.

If you spot an error or a fact that has become false, write to [contact@sirenic.eu](mailto:contact@sirenic.eu?subject=Comparison%20correction): we will correct the page and its survey date.

## 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. The whole catalogue is free to read in the [OpenAPI document](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**

## Routes used and pricing

| Route | Price | What it returns |
| --- | --- | --- |
| `/v1/eu/recherche` | $0.003 | European company search across official registers: company lookup by name, returning European company data in one unified schema. Norway, Estonia, Latvia and Spain (BORME base, hoja key) are served from local copies; Czechia, Slovakia, Finland, Poland and Switzerland are queried live; Denmark and UK when enabled; plus worldwide GLEIF (LEI) coverage of financial entities and large groups. Top 10 matches with country, national ID, status and a score_confiance (0-1 match confidence). |
| `/v1/sanctions/check` | $0.02 | Sanctions screening (AML/KYC): screen a person or company name against 6 official watchlist sources — UN consolidated, EU FSF, US OFAC SDN, UK Sanctions List, French national asset-freeze register, Swiss SECO list — six official lists in one call. Fuzzy watchlist matching with a 0-100 confidence score per hit — never a bare yes/no. Each list reports its entry count, publication date and what that date means. One AML screening call covers UN, EU, OFAC, UK, FR and CH. |
| `/v1/marches/expirations` | $0.05 | Upcoming French public-contract EXPIRATIONS — the predictive layer over DECP open data: contracts whose estimated end date falls inside your window (fenetre_mois, 1-24 months), filterable by CPV prefix (cpv=45) and department, with buyer, incumbent holders, amounts and framework-agreement flag. Buyers typically re-tender 4 to 9 months before expiry: tender anticipation BEFORE publication, not reactive alerts on published notices. Sorted by end date, 50 per page. |

> ⚠️ Contract end dates are estimates, computed from the notification date and the declared duration. This is not an official re-tendering calendar.

> ⚠️ Screening never returns a bare yes/no: every hit carries a 0-to-100 confidence score. Politically exposed persons are not served.

## Frequently asked questions

### Can a private company use API Entreprise?

No. Their page is explicit: only administrative entities are eligible, with software vendors serving administrations potentially qualifying too. Others are redirected to the public company directory.

### What if we are a public body but want your European routes?

Nothing prevents it: the two barely overlap. Use API Entreprise for everything it covers, and our routes for foreign registers, sanctions or contract expiries.
