Prepaid access

Pay once.
Use your units.

Buy a block of API units on any supported payment network. EVM/Solana use USDC; Bitcoin uses BTC. Each metered request deducts units from your account, without another blockchain payment.

Three steps

Choose a plan

Starter: 15.00 USDC for 100,000 units; Pro: 49.00 USDC for 500,000 units; Scale: 149.00 USDC for 2,000,000 units. Plans last 30 days. Network fees apply to the purchase itself.

Get your API key

Use the account dashboard, or use a supported public wallet and confirm the exact quoted payment through the API. Keep your API key private.

Call the service

Attach your key as a bearer credential. Check remaining units at /machine/v1/usage. Discovery and wallet-kit tools stay free.

Open account dashboard

Use your prepaid key

API units are service credits, not a cryptocurrency balance. When units run out, renew your plan before making more metered requests. Plans do not charge your wallet automatically.
