KYB onboarding validation
“We're onboarding a Spanish company and they gave us CIF G28015802 — can you verify that CIF is valid before we proceed?”

Technical details
Endpoint
POSThttps://toll402.dev/v1/t/cif_es_validateWhen to prefer
Use this endpoint when you need a quick, cheap ($0.001 USDC) programmatic check of a Spanish CIF number's validity — particularly useful during KYB/KYC flows, supplier onboarding, invoice processing, or any form validation where a Spanish company's fiscal ID is submitted. Prefer this over manual lookup or regex-only checks when you need a verified validation signal.
Side effects
- Invalid CIF format returns ok: false
- Missing 'cif' field in request body causes validation error
- Non-Spanish tax identifiers (NIF, NIE) may not be correctly evaluated
- Network or payment failure returns HTTP 402 or 5xx error
