How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a structured JSON object indicating whether the tax ID is valid, the detected or confirmed country, format assessment, and possibly entity registration status. Every response includes a cryptographic audit record with chain hashing for compliance and traceability purposes.
Example use cases
Vendor onboarding tax verification
“Before we add this new supplier to our system, can you verify their tax ID GB372986452 is valid? They're a UK company and I need to confirm the number before we process any payments.”
EU VAT compliance check
“We received an invoice from a French company claiming VAT number FR40303265045 — can you validate it's real and correctly formatted before we apply zero-rating on the transaction?”
KYB automated due diligence
“As part of our know-your-business check, validate the tax ID 12-3456789 for a US company — it might be an EIN, and I need the result with an audit trail for our compliance records.”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/tax-id-validateWhen to prefer
Choose this endpoint when you need validated, auditable tax ID verification across 27 countries in a single call, especially when compliance audit trails with cryptographic hashing are required. Prefer over generic regex-based validators when you need actual registration lookups rather than just format checking, and when the result needs to be stored or presented as part of a regulated KYB/KYC workflow.
Side effects
- Missing or empty tax_id parameter returns validation error
- Unrecognizable tax ID format that doesn't match any known country pattern returns invalid result
- Ambiguous tax ID without country_code that cannot be auto-detected may return uncertain or error result
- Network timeout or upstream data source unavailability returns 5xx error
- Invalid ISO country_code provided returns parameter error
