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 validation result indicating whether the Saudi VAT number is valid or invalid, along with an error message or reason if the number fails validation (e.g. wrong length, bad check digit, invalid format).
Example use cases
Invoice compliance check for KSA supplier
“Before I process this invoice from our Saudi supplier, can you verify their VAT number 310122393500003 is actually valid?”
Onboarding form validation for Saudi businesses
“A new customer just submitted a registration form with Saudi VAT number 300075601200003 — can you check if that number passes validation before we accept them?”
Bulk supplier data quality audit
“I have a Saudi vendor listed in our system with VAT number 300000000000003 — can you confirm whether that's a properly formatted and valid Saudi tax ID?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/vat_sa_validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, offline, per-call validation of Saudi VAT numbers without building your own validation logic. It is ideal for invoice processing pipelines, supplier onboarding flows, or data quality checks where you pay only per call with no signup or API key required. Prefer this over manual regex checks when you need authoritative check-digit validation.
Side effects
- Input missing or empty string returns validation error
- Non-numeric or incorrectly formatted input (not 15 digits) returns invalid result
- Check digit mismatch causes invalid result with explanation
- Network or payment failure returns HTTP 402 or 5xx error
