How this service works
x402 seller rail on eip155:8453 — USDC on Base. Serves a signed manifest ($0.01), drift audit ($0.05), and integration brief ($0.25). Pay with EIP-3009 exact scheme via the x402 facilitator.
Output
A JSON object containing the manifest ID, human-readable name, the seller's USDC payout address on Base (eip155:8453), network identifier, and version string — everything an agent needs to construct a valid x402 payment before calling a premium endpoint.
Example use cases
Pre-payment capability discovery
“Before I pay anything, pull the signed manifest from this x402 seller on Base so I can see all available endpoints, their prices in USDC, and the payment address I need to send to.”
Verify seller wallet before transacting
“Get the manifest from the Agentic-SaaS x402 seller so I can confirm the payTo wallet address on eip155:8453 before I authorise any EIP-3009 payment.”
Catalogue x402 products and pricing
“Retrieve the x402 seller manifest and list out every product it offers — the signed manifest at $0.01, the drift audit at $0.05, and the integration brief at $0.25 — so I can decide which one to buy.”
Technical details
Endpoint
GEThttps://x402-seller-mainnet.wansolek.workers.dev/v1/manifestWhen to prefer
Use this endpoint as the first step whenever an agent needs to interact with this x402 seller: it is the cheapest call ($0.01) and returns the authoritative payment address, network, and product catalogue needed before making any higher-value call like the drift audit ($0.05) or integration brief ($0.25). Prefer it over hardcoding payment details, since the signed manifest is the canonical source of truth for the seller's current configuration on Base.
Side effects

- Invalid method — only GET, HEAD, DELETE accepted
