How this service works
Complete x402 quickstart bundle: v2 Base USDC seller endpoint + EIP-3009 buyer client + deterministic product bundle + tests.
Output
A binary bundle (e.g. zip or tar) containing: a v2 Base USDC x402 seller endpoint implementation, an EIP-3009-compatible buyer client, a deterministic product bundle definition, and a test suite — ready to deploy or study as a reference implementation.
Example use cases
Bootstrap x402 payment-gated API
“I want to build a payment-gated API using x402 on Base — can you download the quickstart bundle so I have a working seller endpoint, buyer client, and tests to start from?”
Learn EIP-3009 buyer client pattern
“I'm trying to understand how to implement an EIP-3009 buyer client for x402 — can you fetch the loop2 quickstart bundle so I can see a real working example?”
Integrate x402 USDC micropayments
“I need a reference implementation for charging $0.001 USDC per API call using the x402 protocol on Base — please retrieve the quickstart bundle with tests included.”
Technical details
Endpoint
GEThttps://loop2-quickstart.manhliemcn4euwlu.workers.dev/mkt/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a ready-to-run x402 protocol reference implementation on the Base network using USDC, specifically including both the seller (server) and buyer (client) sides with EIP-3009 authorization, plus tests. Prefer this over generic Web3 payment tutorials when you want a working, deployable code bundle rather than documentation.
Side effects
- Payment not included or invalid — returns HTTP 402 with payment requirements
- Invalid format query parameter — may return 400 or unexpected content type
- Network timeout on Cloudflare Worker — returns 5xx
- Unsupported HTTP method — schema only allows GET, HEAD, DELETE
