01 — How it works

Built for agents.
Works for humans.

Buy credits once. Use them as needed. No subscriptions, no surprise bills.

01
Buy credits

Pay via Stripe, USDC, or SOL. Credits land in your account instantly.

02
Get your key

Receive an API key immediately. Pass it as x-api-key on every request.

03
Query the data

Enrich a company, query D2C brands by fit score, or run a live checkout verification.

04
Credits deduct

1 credit per enrich or query. 3 credits for live checkout scan. Check balance anytime.

02 — Agent-native

Autonomous agent payments

AI agents can discover pricing, pay with USDC or SOL from their own wallet, receive an API key, and start querying — no human in the loop. Check /payments/quote for programmatic pricing discovery.
