eu-verify — European business verification for AI agents

Your agent can verify any European business partner — and pay for it by itself.

Company existence (official French SIREN registry) · insolvency records (BODACC) · EU VAT validation before invoicing (VIES) · SIRET / IBAN / LEI checks · address verification · email deliverability · French business-day deadlines · EU public tenders.

No account. No API key. Each call costs $0.001–$0.01 in USDC on Base, paid automatically through the x402 protocol — the payment is the authentication.

Why your agent needs this

Every intra-EU B2B invoice legally requires a valid VAT number. Every serious supplier onboarding requires a company existence check. These are actions that procurement, compliance and due-diligence agents repeat thousands of times — and the official European data behind them was never packaged for agents. Now it is.

validate_vat_eu	Is this EU VAT number valid? (pre-invoicing check)	VIES (European Commission)	$0.005
validate_siret_fr	Is this SIREN/SIRET well-formed? (offline checksum)	ISO/Luhn	$0.001
validate_iban	Is this IBAN valid? (85 countries, offline)	ISO 13616 mod-97	$0.001
lookup_lei	Resolve a Legal Entity Identifier	GLEIF (official)	$0.005

Buyers are never charged for empty or failed answers (an upstream failure returns an error before settlement). No personal data is served (GDPR: director names are stripped from registry answers).

Use it from an agent (MCP)

Claude Code:

claude mcp add --transport http eu-verify https://data.greeneris.io/mcp

Cursor / any MCP client (mcpServers config):

{
  "mcpServers": {
    "eu-verify": { "url": "https://data.greeneris.io/mcp" }
  }
}

Then just ask: "Check that ACME SARL exists, validate their VAT FR12345678901, and tell me if they have insolvency proceedings."

Payments over MCP: a paid tool called without payment returns the x402 quote in the response _meta; x402-aware MCP clients (e.g. the x402 Python SDK's MCP client, AWS Bedrock AgentCore) attach the USDC payment and retry automatically. Clients without wallet support can read the quote and fall back to the HTTP API.

---

Use it over plain HTTP (x402)

Every endpoint answers HTTP 402 with a machine-readable quote until paid:

curl -i "https://data.greeneris.io/v1/fr/company?q=airbus"
# HTTP/1.1 402 Payment Required
# payment-required: eyJ4NDAyVmVyc2lvbiI6Miw...   <- base64 quote (price, payTo, network)

Paying client in Python (~15 lines, examples/buy_with_python.py):

from eth_account import Account
from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.evm.exact import register_exact_evm_client

buyer = Account.from_key(PRIVATE_KEY)          # a wallet holding a little USDC on Base
client = x402Client()
register_exact_evm_client(client, buyer)

async with x402HttpxClient(client) as http:    # reads the 402, pays, retries
    r = await http.get("https://data.greeneris.io/v1/eu/vat-check?cc=IE&vat=6388047V")
    print(await r.aread())
