Overview

AI-generated overview

Remote x402 gateway that lets an assistant buy pay-per-call crypto, DeFi, wallet-risk and market-data services in USDC, plus one free service listing.

What you can do
  • List the paid services the gateway sells, with prices and paths
  • Score token and wallet risk: Solana rugcheck scoring, airdrop and dust-token defense, wallet portfolio valuation
  • Analyze DeFi liquidity pools and fetch live crypto prices and gas fees for Ethereum, Base and Polygon
  • Search NFT collections on Solana and on-chain AI agents in the ERC-8004 registry
  • Check data lineage blast radius in DataHub and track game deals and release dates
  • Run agent research tasks and score or route across model providers in the Sovereign Router pool
When to use it
Useful when an assistant needs on-demand crypto market, wallet-risk or DeFi data without signing up for API keys, and the caller is set up to pay small per-call USDC charges. Also handy for quick gas price lookups, NFT and agent discovery, or DataHub impact checks.
Requirements
A remote streamable HTTP endpoint; no package install, API key or environment variable is declared. Each paid tool is billed per call in USD (from $0.005 to $0.05) and settled in USDC on Arc via the x402 payment flow, so the calling agent needs a funded wallet and x402 payment support.
Before you install
Most tools cost money per call, so automated or repeated calls spend USDC from the agent's wallet. The README describes an autonomous agent wallet contract deployed on the Arc testnet with a test wallet, so treat it as experimental. Token risk scores and market data are third-party sourced and should not be treated as financial advice. Some tools send addresses or queries to external services such as DexScreener, Magic Eden, rugcheck and DataHub.

Installation

In SourceWeft

  1. Open X402 Gateway in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/net.gentechlabs%2Fx402-gateway/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Encode Club Programmable Money Hackathon — Circle × Arc
Track: Agentic Economy — AI agents that hold wallets, pay and transact autonomously in USDC Repo (public): https://github.com/Gentech-Labs/programmable-money-x402

The Problem

AI agents need to pay for APIs, compute, and data — but there's no standard way to do it programmatically. Every integration means manual API keys, subscriptions, or custom payment flows. Real agent autonomy requires programmable money.

The Solution

x402 on Arc — a payment gateway that bridges Circle's USDC infrastructure with the HTTP 402 Payment Required standard:

  1. An agent calls an API → gets HTTP 402 with payment requirements
  2. The agent pays USDC on Arc (sub-second settlement, USDC fees)
  3. Access is granted — no API keys, no signups, no human in the loop

This is programmable money for the agent economy.

Architecture

Agent → HTTP Request → x402 Middleware → HTTP 402 + Arc USDC invoice           ↓                                        ↓    Access Granted  ←  Payment Verified  ←  Agent pays USDC on Arc

Track Focus

Agentic Economy — AI agents hold wallets on Arc, pay for services in USDC autonomously, using Circle's stablecoin-native L1 for sub-second settlement.

Components

  • x402 Gateway — middleware that drops into any API, handles 402 → payment → access
  • Arc Settlement Layer — USDC transfers via Circle's infrastructure on Arc
  • Agent SDK — one function call for any agent to pay x402 APIs
  • Playground — test transactions, manage wallets, see the flow live

Why Arc + Circle

Arc is built for this — USDC as the native fee token, sub-second finality, and programmable wallet infrastructure. x402 on Arc means agents settle payments in the same block they're requested.

What the deployed contract does: the agent wallet autonomously holds USDC, can be funded by any party, and executes agent-initiated transfers with a safety timeout — programmable money for agents, live on Circle's Arc L1.
