FAQ

What is d402?

d402 is a decentralized payment protocol that lets you monetize any skill, API, or digital service with pay-per-use pricing. It uses USDC on Base for instant, low-cost settlement.

How do payments work?

When someone calls your skill, d402 automatically handles the payment flow using HTTP 402 and EIP-712 signatures. The caller pays in USDC, and you receive funds directly to your wallet — no middleman.

Do I need an API key or account?

No. d402 is permissionless. You just need a wallet address to receive payments. Callers use a local encrypted wallet with configurable spending policies.

What can I monetize?

Anything that can be called programmatically — AI skills, APIs, MCP servers, datasets, compute resources, or any digital service.

What are the fees?

d402 itself charges no platform fees. You only pay standard Base network gas fees, which are typically fractions of a cent per transaction.
