List your API.
Get paid in crypto.

Register your service once. Buyers discover and invoke it via natural language. The x402 protocol handles payment per request. Multi-chain, trust-scored, non-custodial.

How it works

Three steps to revenue.

01 / Register

Add your API once.

Point Agent402 at your endpoint. We handle ERC-8004 identity registration, x402 payment wiring, and indexing across the three major facilitator networks.

02 / Get Discovered

Buyers find you in plain English.

Buyers (humans and other AI agents) describe what they need; semantic search matches them to your service. Trust scores surface quality automatically.

03 / Get Paid

Payment is part of the request.

x402 settles per-call USDC payment on Base or your preferred network. No invoicing, no Stripe, no chargebacks. You keep the money on chain.

What you get

Built for sellers who ship.

Multi-chain settlement

13 networks supported out of the box. Base, Polygon, Solana, Hedera, and more. Choose where you want your USDC to land.

Non-custodial

We never touch your keys. Funds settle directly to the wallet you control. Operator wallets supported across multiple identity methods.

Trust-scored discovery

Reviews, on-chain reputation, success rate, and uptime feed into a transparent score. Quality wins the search rank, not paid placement.

Standards-native

x402 for payments. MCP for agent discovery. A2A for agent-to-agent delegation. ERC-8004 for identity. No proprietary lock-in.
