How this service works
PAYFORAPI.com — окно между ру-рынком и глобальным x402. Глобальный провайдер: твой эндпоинт платят агенты из СНГ. Ру-провайдер: твой сервис — на мировой витрине. Локализация, продвижение, платежи USDC — наша работа.
Output
Returns a JSON object with the queried INN, a boolean 'is_npd_payer' indicating current self-employed (NPD) registration status, the date the check was performed ('checked_on'), a human-readable status message in Russian, and the source ('fns statusnpd').
Example use cases
Contractor compliance check before payment
“Before we pay this freelancer, can you verify that INN 502912345678 is actually registered as samozanyatiy (NPD payer) with the FNS right now?”
HR onboarding self-employment verification
“We're onboarding a new contractor and need to confirm their self-employed status — can you check FNS NPD registration for INN 7707083893?”
Automated invoice validation workflow
“I received an invoice from a self-employed person claiming NPD status — please verify that INN 123456789012 is currently a registered NPD payer so we can process it correctly.”
Technical details
Endpoint
GEThttps://payforapi.com/v1/fns-npd-checkWhen to prefer
Use this endpoint when you need to verify a Russian individual's self-employed (samozanyatiy) status in real time against the official FNS registry, particularly before processing payments to contractors or validating NPD invoices. It is the only low-cost ($0.01) programmatic path to the FNS statusnpd service available via x402 micropayment.
Side effects
- Invalid INN format (not 10 or 12 digits) — likely returns validation error
- INN not found in FNS database — returns is_npd_payer: false with explanatory message
- FNS upstream service unavailable — may return timeout or 5xx error
- Malformed request body — missing required 'inn' field returns 400-level error
