How this service works
Pay-per-call Brazilian business intelligence for AI agents, paid via x402 in USDC on Base.
Output
A JSON object containing the identifier type (e.g. 'cnpj'), a boolean 'valid' field indicating whether the identifier passed validation, and the normalized 'value' string of the identifier submitted.
Example use cases
Verify Brazilian supplier registration
“Before we onboard this Brazilian vendor, can you check if their CNPJ 11.222.333/0001-81 is valid?”
Validate customer CPF at checkout
“A customer just entered CPF 123.456.789-09 during checkout — can you verify whether that's a valid Brazilian taxpayer ID?”
Confirm Brazilian phone number authenticity
“I have this Brazilian phone number +55 11 91234-5678 from a lead form — can you check if it's a valid Brazilian phone number?”
Technical details
Endpoint
GEThttps://br-intelligence.brverify-api.workers.dev/v1/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate Brazilian-specific identifiers — CPF (individual taxpayer), CNPJ (company registration), EAN13 (product barcode), NFe (fiscal notes), or Brazilian phone numbers — especially in KYC, vendor onboarding, e-commerce checkout, or compliance workflows targeting Brazil. At $0.005 USDC per call via x402 on Base, it is cost-effective for high-volume per-transaction validation without a subscription.
Side effects
- Invalid or malformed identifier value returns valid: false
- Unsupported identifier type results in schema validation error
- Payment failure via x402 (insufficient USDC balance on Base) prevents the call from completing
- Missing required 'type' or 'value' query parameters returns an error
- Network timeout from the Cloudflare Worker
