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
A JSON object with an 'ok' boolean field indicating whether the supplied MERSİS number is structurally valid (true) or not (false). The check is performed offline without contacting Turkish government databases.
Example use cases
Onboarding Turkish business partners
“We're onboarding a new Turkish supplier and they gave us MERSİS number 1234567890123456 — can you verify that number is structurally valid before we proceed?”
Bulk invoice compliance check
“Before we process this invoice, please validate the MERSİS number 9876543210987654 listed on it to make sure it's a legitimate Turkish company identifier.”
KYB workflow for Turkish entities
“As part of our know-your-business check, can you confirm whether 0987-6543-2109-8765 is a valid MERSİS registration number for a Turkish company?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/mersis_validateWhen to prefer
Use this endpoint when you need a fast, offline, zero-signup structural validation of a Turkish MERSİS company registration number — ideal for compliance pipelines, onboarding flows, or invoice verification where you don't need a live government registry lookup. Prefer this over full registry lookups when speed and cost matter and structural correctness is sufficient.
Side effects
- Invalid or missing 'value' field returns a validation error
- Non-numeric or incorrectly formatted input may return ok: false
- Network timeout or service unavailability returns an HTTP error
- Passing a non-MERSİS Turkish identifier (e.g. VKN/tax number) may produce incorrect results
