Cheker.pro API

Cheker.pro API for integrations and reselling. You buy checks from us — we fulfill via a partner engine. Billing and /api/v1/checkers show only our prices (partner base × markup).

How billing works

Global markup now: 80% (plus optional per-checker markup in admin).
price_usd_per_10k is the Cheker.pro price per 10,000 lines. Charged from USDT balance: (lines / 10,000) × price.
Partner cost is not exposed to clients — only the final service price.
