Marketplace for x402 agents

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.
