/ 03 — How it works

Four steps between intent and answer.

01

Agent discovers

An autonomous agent queries the on-chain registry for a tool it needs — filtered by schema, price, rating.

02

Payment signed

Agent signs a pay-for-tool instruction in USDC. The transaction creates a PaymentRecord PDA bound to this exact call.

03

Gateway verifies

Our gateway reads the PDA, confirms the payment hasn't been spent, and proxies the MCP call to the tool's endpoint.

04

Publisher earns

USDC lands in the publisher's vault the moment the call settles. No settlement delay, no Stripe, no chargebacks.

/ 04 — Ship it

Every tool
has a price tag.

Publish a tool in under five minutes. On-chain registry, USDC payouts, instant discovery.
