Pay-per-call x402 services for agents: risk scoring, DeFi, wallet and market data.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for x402-gateway, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

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:
- An agent calls an API → gets HTTP 402 with payment requirements
- The agent pays USDC on Arc (sub-second settlement, USDC fees)
- Access is granted — no API keys, no signups, no human in the loop
This is programmable money for the agent economy.
Architecture
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.
