How this service works

Verify payment received on Base
“Check if wallet 0xDEADbeef1234567890abcdef1234567890abcDEF has received any USDC on Base yet — I'm waiting on a payment and want to confirm it landed.”

Technical details
Endpoint
GEThttps://phases-prot-shine-royal.trycloudflare.com/x402/base-wallet-balanceWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.01 USDC) read-only balance check for a single EVM address on Base mainnet without running your own node or managing RPC infrastructure. Ideal for agents that need to verify wallet balances, confirm payments, or enrich address data with live on-chain state.
Side effects
- Invalid or malformed EVM address (not matching 0x + 40 hex chars) returns a validation error
- RPC node unavailability or Base mainnet downtime may cause lookup failure
- Address with no on-chain activity may return zero balances without error
- Rate limiting or payment failure for the $0.01 USDC x402 fee may block the request
