Comparing companies on official data

Comparing companies is the easiest way to produce a wrong but convincing figure. Two companies in the same sector, one reporting statutory accounts and the other consolidated, are not comparable — and a well-formatted table makes you forget it. /v1/comparer returns per-axis rankings and a comparability block that tells you when to stop.

Never an overall winner, deliberately

An overall rating implies a weighting between revenue, profitability, structure and risk. That weighting depends on your decision — shortlisting a supplier is not the same trade-off as granting payment terms. So we return a ranking per axis and let you weight, rather than hiding a trade-off inside a single number.

The six guards against a false comparison

Revenue at 0 is treated as missing, not as zero.
The accounting scope is declared: statutory or consolidated, and series where the source conflates the two are flagged.
A no-conclusion score stays no-conclusion: it is not replaced by a median value to fill the table.
Financial years with different end dates are flagged — comparing a 2024 year with a 2022 year is not a comparison.
The presence of a holding company in the batch is flagged: its accounts do not read like an operating company's.
Sanctions screening is returned as a per-company boolean, with no ranking — you do not “rank” companies on a sanctions list.

The quote is signed and priced per company: the amount is the unit price times the number of company numbers passed, known before settlement.

Placing a company against its sector

Comparing two companies with each other does not tell you whether either is normal. /v1/secteur/{code_naf}/benchmarks returns, for an activity code at any level, the number of active companies, the median age with quartiles, the workforce-bracket distribution and — as soon as at least 5 companies file public accounts — median revenue, margin, result and debt ratio. 2,934 sectors are covered.

Aggregates only, no personal data, and sectors with fewer than 5 companies are excluded — an aggregate over three companies re-identifies its members.

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.

Routes used and pricing

Route	Price	Sample	What it returns
`/v1/comparer`	$0.12 / entité	free sample	Company comparison: compare 2 to 5 French companies side by side in one call on official company data — identity, deterministic default-risk score, latest filed accounts (statutory scope) and BODACC insolvency alerts. Benchmarking for supplier selection and vendor shortlist: per-axis rankings, never an overall winner, plus a comparabilite block that flags NOT comparable companies (different sectors, sizes, a holding in the batch). Billed PER COMPANY: signed quote = $0.12 x number of SIREN.
`/v1/secteur/{code_naf}/benchmarks`	$0.05	free sample	Sector benchmarks and sector statistics for a French NAF activity code (any level: division, groupe, classe, sous-classe): number of active companies, median company age (with quartiles), workforce-bracket distribution, and — when at least 5 companies file public accounts — median revenue, EBITDA margin, pre-tax result and debt ratio. Peer comparison in one call: place a company against its peers. Aggregates only, no personal data; sectors with fewer than 5 companies are excluded.
`/v1/entreprise/{siren}/finances`	$0.01	free sample	Financials of a French company (annual accounts filed at INPI, Banque de France ratios): revenue, EBITDA, net income, debt, financial autonomy — ONE row per fiscal year, each graded (qualite: exploitable / a_verifier / non_exploitable, anomalies, doubtful fields); source rows set aside are served in exercices_ecartes with their reason. Consolidated accounts are served apart and graded the same way. Includes the INPI-keyed tax-form line items (up to 20 years) and a perimetre_comptable block.

Frequently asked questions

How many companies at most?

Five. Beyond that, a comparison table stops being useful; better to run the KYB batch and then compare the axes you care about.

What if the comparability block says “not comparable”?

Read it as an answer, not an error. It tells you the table you were about to show would have been misleading. The useful next step is usually to compare each against its own sector rather than against the other.
