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 JSON object with an 'ok' boolean indicating whether the submitted NIT (including its check digit) is structurally valid according to Colombian DIAN rules.
Example use cases
Vendor onboarding NIT check
“Before I add this Colombian supplier to our system, can you verify that their NIT '900455523-1' is structurally valid with the right DV?”
Invoice validation before payment
“I have an invoice from a Colombian company with NIT '8001972684' — check if that NIT is valid so I know it's safe to process the payment.”
B2B form input validation
“A user just submitted NIT '700085264-3' in our onboarding form — is that a valid Colombian tax ID?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/nit_validateWhen to prefer
Use this endpoint when you need a fast, offline-style structural validation of a Colombian NIT number including its DV check digit — for example, during vendor onboarding, invoice verification, or form input validation. Prefer this over a full DIAN registry lookup when you only need to confirm the NIT format and check digit are correct, not that the business is actively registered.
Side effects
- Malformed NIT string (missing digits, extra characters) returns ok: false
- Invalid check digit causes validation failure
- Network or gateway errors return HTTP error codes
- Payment failure via x402 if USDC wallet is insufficient
