x402-micro-tollgate
Visa for AI agents that can’t hold a card.
Second-scale settlement bridge for agent traffic — the Web3 tollbooth that clears USDC micropayments and takes 0.1%.
为千万级无支付能力的 AI Agent 提供秒级过桥清算，抽成 0.1% 的 Web3 版 Visa 收费站
Security backed by Coinbase CDP. We don't touch your keys or settle payments on custom cryptography — EIP-3009 authorization nonces are single-use at the CDP facilitator (source of truth for on-chain uniqueness). The gateway hardens four buyer/seller trust surfaces: payment-proof replay/race, SSRF on URL fetch, upstream bypass (shared-secret trust header), and Base congestion / settle-latency (pending + retry same proof — never treat HTTP timeout alone as “payment failed”).
What it is
A thin self-hosted tollgate in front of your API or MCP tools. When an agent calls a paid route, it gets HTTP 402 as a price tag (not a hard deny). It pays a small USDC (or configured USDT) amount; you deliver. Default clearing is Base + USDC via Coinbase CDP; multi-network accepts are env-driven (see matrix below). Humans can still hit a free path; agents convert at the booth.
Self-host is free (MIT). Repo: github.com/kevin2003050666-coder/x402-micro-tollgate · Questions: 2767111713@qq.com
Not an official Coinbase product. Not a full agent marketplace. Not a billing SaaS. A sharp Visa-style tollbooth. Not fiat custody.
Why this exists: MANIFESTO.md — pain, engineering, on-chain proof, MIT.
Network × asset matrix
Default deploy profile: Base USDC only (dev: Base Sepolia). Enable multi with NETWORKS + ASSETS or ACCEPTSJSON / X402 aliases. Browser HTML 402 shows a chain + asset picker when more than one accept is configured.
USDT on EVM typically uses extra.assetTransferMethod: "permit2" (not EIP-3009). FeeSplitter production path remains Base + USDC; other chains are config stubs under contracts/deployments/.
