How this service works
Pay-per-call tools for AI agents: x402 pre-flight checks (is this endpoint safe to pay?), web pages as clean markdown (with optional JavaScript rendering), Latin American tax-ID validation, npm/PyPI/GitHub lookups, and URL health checks. No API keys, no accounts — pay per request in USDC.
Output
Returns a JSON object with a count field and a results array. Each result includes the original ID, the country code, a result object containing a valid boolean, a reason string (empty on success, descriptive on failure), the country code in uppercase, the id_type (e.g. CNPJ, CUIT, RUT, RFC), and a normalized string representation of the ID without punctuation.
Example use cases
Vendor onboarding tax ID check
“Before we add these new Brazilian and Argentine suppliers to our system, can you batch-validate their tax IDs — CNPJs 11.222.333/0001-81 and 60.746.948/0001-12, and CUIT 20-30678774-6 — and let me know which ones are legitimate?”
E-commerce checkout tax ID verification
“A customer just entered their Chilean RUT as 12.345.678-9 during checkout — can you verify whether it's a valid RUT before we process their order?”
Bulk compliance audit for LATAM entities
“I have a list of ten Mexican RFC codes from our records that I need audited for validity — can you run them all through a checksum validation and tell me which ones fail?”
Technical details
Endpoint
POSThttps://agents.supremeai.ca/v1/validate/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify the mathematical/checksum validity of Latin American tax IDs (Brazil CNPJ, Argentina CUIT, Chile RUT, Mexico RFC, Peru, Paraguay) without needing a full government registry lookup. It excels at batch processing multiple IDs in one pay-per-call request, is keyless (no account setup), and costs a flat $0.01 USDC per call regardless of batch size. Prefer it over full KYC services when you only need format/checksum validation as a first-pass filter before more expensive registry checks.
Side effects
- Unsupported country code returns an error or unrecognized result for that item
- Malformed or empty id field may return valid:false with a descriptive reason
- Network or payment failure (402 / x402 protocol) prevents the call from completing
- Batch array is empty or missing, causing a request validation error
- ID that passes checksum format but is not officially registered still returns valid:true — this endpoint only checks the checksum algorithm, not a government registry
