Merx — European Business Data

bricepourle13/merxprotocol

A streamable HTTP server for European business intelligence, focused on French commercial registries and EU VAT systems. You get endpoints for validating VAT numbers across EU member states, looking up French company registration data (SIREN/SIRET checks, most likely), and searching legal entity information. Reach for this when you're building compliance tools, onboarding flows that need to verify business customers, or any app dealing with European B2B transactions where you need to confirm a company is legitimate and tax-registered. The remote URL suggests a hosted service, so no local setup required. Useful if you're tired of manually checking VIES or scraping Infogreffe.
