Hunted bySirenicSirenic

Official French & European company data as a pay-per-call API for AI agents. One call returns a KYB file: identity, officers, filed financials, BODACC alerts, and sanctions screening of the company and each officer vs the 5 official lists. Paid in USDC via x402, no account, no API key. Also an MCP server (25 tools).

Hi Product Hunt 👋 I'm Côme, solo builder from France.

AI agents can't sign up for anything: no email to verify, no card to enter, no API key to generate. So most data APIs stay closed to them. Sirenic flips that: the HTTP request carries its own payment.

You call an endpoint, get back a 402 with a price, your agent signs a USDC or EURC payment (x402, on Base), calls again, and gets the data. No account, no API key, and a failed request is never charged. Every paid response is Ed25519 signed, so an agent can verify offline that the data really came from Sirenic, unmodified.

It serves official French and European company data from open government registers: search 30M companies, full profiles, filed financials, BODACC legal alerts, one-call KYB files with sanctions screening of the company and each officer against 6 official lists, and a $1 intelligence report that cross-references every block into closed-list signals and a rule-based verdict. Belgium, UK, Norway, Estonia, Latvia and worldwide via GLEIF are in one unified schema too. Prices run $0.001 to $1.00 per call.

It's also an MCP server (29 tools), so Claude or Cursor plug in with one line:

claude mcp add --transport http sirenic https://api.sirenic.eu/mcp

It's early and I'm one person. I'd love feedback on the pay-per-call model, and which datasets would actually be worth a per-call price.

Happy to answer anything here 🙏

Comment highlights

The pay-per-call model is interesting because it changes how developers think about data access. Curious whether your biggest challenge has been improving the dataset itself, or making it easy for AI agents to know when they actually need to query it.

A bulk lookup endpoint would be huge, even if it costs more per call. Right now if an agent needs to screen a list of vendors or counterparties it has to loop one call at a time, which kills latency and adds unnecessary network chatter. Adding a single POST that accepts up to maybe 50 SIRENs and returns an array of KYB files in one response would make this way more useful for onboarding flows.

paid a few cents in USDC and got back a clean KYB file with BODACC hits already flagged, way less friction than the usual vendor onboarding for a one-off compliance check.
