# Sirenic or Pappers: which one for which need

Pappers and Sirenic answer the same questions through two opposite models: on one side a very rich record billed in credits with per-field surcharges, on the other narrow routes billed per call. The facts below come from a catalogue survey on 2026-08-06 and a calibration campaign run on 2026-08-11 on a real paid account — not from reading their marketing page.

## What Pappers 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.

- They serve **politically-exposed-person** status. Sirenic does not serve it at all — the 2026-08-07 feasibility review said no, because the French HATVP publishes “[Données non publiées]” instead of dates of birth, so an exact namesake would come out as a “strong match”.
- Their autocomplete is **free and key-less**, with a daily quota: an excellent entry point for a public form.
- One very rich record for 1 credit beats our separate calls when you want **everything** about a company and have no reason to pick and choose.
- They cover **French non-profit records (RNA)** and produce several PDFs we do not (their own extract, the INSEE situation notice).
- On one case in our calibration (BOBION & JOANIN), their rating was better founded than ours: it read **net cash** and **tax and social debt**, two dimensions our scoring did not have at that date.

## When to choose Pappers, honestly

- You want **everything** about a company in a single call and have no reason to pick and choose: their single record is cheaper than our separate calls.
- You need **politically-exposed-person** status: we do not serve it at all, and we explain why on our screening page.
- You want **free key-less autocomplete** in a public form.
- You work with **non-profits** or need their specific PDFs.

## Pappers: what we found

Surveyed on 2026-08-11, source: [https://www.pappers.fr/api](https://www.pappers.fr/api). Every line is verifiable by you, at the same address.

- France API v2: 23 routes listed in the catalogue on 2026-08-06, authenticated with an `api-key` header.
- Billing in **credits**, with a surcharge per requested field: on the paid account used on 2026-08-11, financial scoring and non-financial scoring cost **30 credits each**, sanctions and politically-exposed-person status 1 credit, phone and e-mail 3 credits.
- The `/entreprise` record is very dense for 1 credit (310 KB measured, 188 filings, 20 sets of accounts, 10 financial years), but the dedicated `/entreprise/comptes` call was billed **20 tokens** on that same account.
- Their financial scoring **abstains on holding companies**: “Secteur non couvert” (sector not covered) was returned for 4 of the 27 company numbers in the 2026-08-11 calibration sample.
- For 2 companies in that sample, the score served was based on accounts from **2017 and 2023** even though 2024 and 2025 filings existed: their rating is not recomputed at call time.
- Their politically-exposed-person data comes from **Wikidata** (visible in the compliance response).
- Automation: 7 Zapier actions and 4 Make modules, but **no trigger** on either platform; their n8n node published on npm in March 2026 has stayed at version 0.1.0.

> ⚠️ Their euro price list is not reproduced here: `www.pappers.fr` returned 403 to our 2026-08-19 checks, and we do not publish a competitor's pricing from second-hand sources. See their own pricing page.

## 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.
- **The score is recomputed at call time**, on the latest available filing — the direct counterpart to the stale-accounts finding above. And it returns its scorecard, component by component, so it can be challenged.
- **Holding companies are scored**, with a confidence level stating how cautiously to read it, rather than an abstention. Both positions are defensible; this one lets you judge instead of leaving you with nothing.
- **Insolvency proceedings surface in real time.** Same sample: 8 of 8 proceedings flagged by our alerts, 0 of 8 by their financial scoring — a batch-recomputed score has not seen today's announcement.
- **Triggers, not just actions.** Our watchlist pushes a signed webhook when something moves; they expose no trigger on Zapier or Make.
- **Official sanctions sources only** (UN, EU, OFAC, UK, French freezes, SECO). Their politically-exposed-person data comes from Wikidata, visible in their own response.
- **Deep European annual accounts**: Belgian, Finnish, Danish, Slovak, British, Swedish, Latvian, Estonian.

## The foundation, in measured figures

Measured in our database on 2026-08-19: 29,922,486 company numbers and 43,896,818 establishments, 6,542,232 financial years across 1,586,046 companies, 3,402,583 detailed tax-form line items, 9,196,396 registry filings, 765,960 public contracts of which 173,633 expire within 18 months, 130,165 names across 6 official sanctions lists, 47,731 authorisations from 9 authorities, 138,020 regulated industrial sites and 2,934 sectors with 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/kyb/{siren}` | $0.15 | Company lookup KYB — Know Your Business verification of a French company in one call: official company data for due diligence, compliance and customer onboarding: identity, officers, BODACC legal alerts (insolvency, deregistration), filed financials, sanctions screening of the company and each officer against the 6 official lists, computed VAT number and a completeness score. Per-block provenance: every block states its official register and as-of date. |
| `/v1/score/defaillance/{siren}` | $0.10 | Credit risk scoring for a French company: a default-risk score (0-100) at ~12 months from a transparent scorecard — filed financial ratios (structure, profitability, liquidity, net cash, debt service, trend), company age, and a hard BODACC override (open insolvency/liquidation, or closure for insufficiency of assets). Returns the score, a qualitative band, every component with its threshold, and a confidence level. Decision-support indicator — NOT a solvency opinion or credit rating. |
| `/v1/surveillance/creer` | $0.05 (30 j) · $0.135 (90 j) · $0.50 (365 j) / entité | Company monitoring for France: a 30, 90 or 365-day surveillance watchlist (?duree=), recurring KYB & compliance alerts. Each target checked DAILY against official sources; Ed25519-signed webhook and/or e-mail digest, always pollable. Company targets (SIREN): BODACC, status, officers, sanctions/AMF blacklist, PSAN/SGP, Seveso, new FR & EU procurement awards. Director targets (dirigeant:Name): new/ended offices. Per target (1-100) x duration: $0.05 / $0.135 / $0.50. No account, no refund. |
| `/v1/eu/entreprise/{pays}/{id}/comptes` | $0.01 | European company financials — Belgian and Finnish company annual accounts, filings list. BE: every published deposit reference at the NBB CBSO (Central Balance Sheet Office, Authentic Data, since 1978), 10-digit enterprise number. FI: fiscal years available as PRH XBRL filings (~5% of Finnish limited companies file digitally; empty filings are filtered out, every listed year carries figures), Business ID NNNNNNN-N. Unique on x402: no other service exposes Belgian or Finnish filed accounts. |

> ⚠️ The default-risk score is a decision-support indicator. It is neither a solvency opinion nor a credit rating in the regulatory sense, and it guarantees no payment.

## Frequently asked questions

### Why do you not publish their euro prices?

Because we could not survey them ourselves on 2026-08-19: their site returns 403 to automated checks. Publishing a competitor's price from a third-party blog would be exactly the kind of unverifiable claim an honest comparison rules out. The credit costs we do quote were measured call by call on a paid account.

### A case where their rating beat yours?

Yes, and we say so: on one company in the sample, their rating read net cash and tax and social debt, two dimensions our scorecard lacked at that date. Our verdict was too confident. That finding is what opened the work to add those dimensions.

### Can I use both?

Yes, and it is often the most rational choice: their record for the overview, our routes for what they do better — recomputed scoring, real-time alerts, European accounts, invoicing checks.
