How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with the queried wallet address and an array of token balances, each containing a symbol (ETH or USDC) and the corresponding numeric amount held on the specified chain.
Example use cases
Pre-payment funds verification
“Before I send that transaction, check if the wallet 0x1234567890abcdef1234567890abcdef12345678 on Base has enough USDC to cover it.”
Portfolio balance monitoring
“What are the current ETH and USDC balances on wallet 0xDeAdBeEf0000000000000000000000000000CaFe on Ethereum mainnet?”
Agent treasury health check
“Check how much ETH and USDC my agent's wallet 0xaabbccddeeff00112233445566778899aabbccdd holds on Base right now.”
Technical details
Endpoint
GEThttps://x402-gateway-production-1f21.up.railway.app/wallet-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, machine-payable lookup of ETH and USDC balances for any EVM wallet on Base or Ethereum mainnet, especially within automated agent workflows that already use the x402 payment protocol. Prefer it over full blockchain node queries when you want a simple REST interface without managing RPC connections.
Side effects
- Invalid wallet address format (not a valid 0x EVM address) returns an error
- Unsupported chain ID outside eip155:8453 or eip155:1 returns a validation error
- Network or RPC issues may cause timeouts or stale data
- Missing required 'address' query parameter returns a 400-level error
- Payment failure via x402 protocol causes the request to be rejected before execution
