European company verification API for AI agents

Verify any European company in a single call. Give a country (FR, UK, IE, NO, FI, SK, PL, CZ) and its national registry number and this endpoint checks existence and status in the official registry, insolvency signals (BODACC for France, registry flags elsewhere), VAT validity against VIES, the LEI record at GLEIF, the legal name against the EU, US OFAC, UN, UK and French sanctions lists, the EORI customs number and the company domain's age and mail setup.

It returns one verdict - pass, review or fail - with a confidence level, the reasons, and a per-check source and timestamp, plus an explicit coverage map that says what was checked, what is structurally not covered for that country and what was temporarily unavailable. This is factual verification of official public records, not a credit score: no payment-behavior data, no probability of default, and a sanctions match always says review, never an automated fail. $0.10 per call in USDC, no account, no API key, never billed on failure.

Endpoint

GET /v1/eu/company-check — $0.10 per call (USDC on Base, x402). Also available as the MCP tool verify_company_eu on https://data.greeneris.io/mcp.
