How this service works
Checks Base wallets for USDC receiving readiness, publishes paid x402 data APIs, and sells fixed-price agent payment, developer-tool, VPS, wallet-risk, and QA implementation work.
Output
Returns a JSON object with agent identity info, payment configuration details (asset, network, price, facilitator), receipt type, and wallet readiness data including whether the address is a smart contract and its current native USDC balance on Base.
Example use cases
Example prompt
“Can you check if the Base wallet 0x820a7bf90d944bb26bfD9b62Ab172Fc3A0829cB9 is ready to receive USDC — I need to know whether it's a contract and what its current native USDC balance is before I send a payment?”
Technical details
Endpoint
GEThttps://x402-wallet-readiness-service.vercel.app/api/agent-commerce-receiptWhen to prefer
Use this endpoint when you need to verify that a specific Base wallet address is properly configured and funded to receive USDC before initiating an agent payment or x402 transaction. It is ideal for pre-flight checks in agentic payment workflows on Base, especially when you need to distinguish between EOA wallets and smart contracts and confirm USDC liquidity.
Side effects
- Invalid or malformed wallet address (not matching 0x[40 hex chars] pattern) returns a validation error
- Missing required 'address' query parameter causes a 400 error
- Payment not fulfilled (x402 flow incomplete) results in a 402 Payment Required response before data is returned
- Wallet address not found on Base network may return zero balances with no error
- Downstream Base RPC unavailability could cause timeout or 5xx error
