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 field — true if the AFM is valid, false if not. The validation is performed offline using the standard Greek AFM checksum algorithm.
Example use cases
Pre-invoice Greek supplier check
“Before I generate an invoice for this Greek supplier, can you verify that their AFM 094259216 is a valid tax number?”
Onboarding Greek business partner
“We're onboarding a new Greek partner and they gave us AFM 998877665 — can you confirm it's a legitimate, correctly formatted Greek tax ID?”
Bulk data cleanup validation
“I have a Greek company's AFM on file as '12 345 678 9' — can you validate it and tell me if it checks out?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/afm_gr_validateWhen to prefer
Use this endpoint when you need a fast, offline, no-external-registry checksum validation of a Greek AFM. It is ideal for pre-flight checks before submitting invoices, onboarding Greek business partners, or cleaning up tax ID data — and does not require a connection to the Greek tax authority (AADE) registry, so it cannot confirm active registration status, only structural validity.
Side effects
- AFM is not exactly 9 digits after stripping spaces — returns ok: false
- Non-numeric characters in AFM — returns ok: false or error
- Checksum digit mismatch — returns ok: false
- Missing required 'afm' field in body — returns a 400-level validation error
