How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object with an 'ok' boolean indicating whether the provided German VAT number passes format validation and authenticity checks. A true value confirms the VAT number is valid; false indicates it is not.
Example use cases
Pre-invoice VAT verification
“Before I send this invoice to my German client, can you verify their VAT number DE123456789 is legitimate and properly formatted?”
B2B onboarding compliance check
“We're onboarding a new German supplier and they gave us VAT number DE811569869 — can you validate it to make sure it's a real registered number?”
Automated accounts-payable validation
“I have a batch of German vendor VAT numbers starting with DE — can you validate 811569869 to make sure it's a genuine German tax registration?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/vat_de_validateWhen to prefer
Use this endpoint when you need to validate a German VAT number (DE-prefixed) specifically, particularly in invoicing, B2B onboarding, or compliance workflows. Prefer this over generic EU VAT validators when the target is exclusively German businesses. It requires no API key and is billed per-call in USDC via x402, making it ideal for agent-driven, low-frequency spot checks.
Side effects
- Invalid or malformed VAT number returns ok: false
- Missing 'vat' field in request body causes a schema validation error
- Non-German VAT numbers (e.g. FR or GB prefixes) may not be supported
- Network or payment failure via x402 protocol returns HTTP 402 or 5xx
