How this service works
Pay-per-call APIs for AI agents over x402: token safety reports, Base and Ethereum on-chain reads, crypto prices, domain checks (DNS, WHOIS, SSL, email), finance data (FX, SEC), worldwide weather forecasts, France alerts, text AI, fun content. USDC on Base, no account, no API key.
Output
A JSON object with the ETH balance (as a decimal string), the Base network identifier, the queried address, and an array of token objects each containing the token contract address, symbol, human-readable balance, and raw balance integer — covering USDC by default and up to 5 additional ERC-20 tokens if specified.
Example use cases
Pre-swap funding check
“Before I do a swap, can you check if 0x60fd97850059dF9600C4E26f09aC58EF51561963 has enough USDC and ETH for gas on Base? Check token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 too.”
Portfolio balance snapshot
“Give me a quick snapshot of the ETH and token balances on Base for wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — include USDC and these two tokens: 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb and 0x4200000000000000000000000000000000000006.”
Payment readiness verification
“I'm about to send a payment on Base — can you confirm that 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD has at least 50 USDC and some ETH for the gas fee?”
Technical details
Endpoint
GEThttps://api.zkrobotics.fr/x402/base/wallet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-API-key, pay-per-call balance check specifically on Base mainnet — ideal for pre-flight funding checks before swaps or payments, portfolio snapshots, or agent pipelines that need live on-chain balances without managing API credentials. Prefer this over general blockchain explorers when you need ETH plus multiple ERC-20 balances in a single call on Base.
Side effects
- Invalid address format (not a valid 0x hex address) returns an error
- Requested token address not found or not an ERC-20 contract returns zero or error
- Base mainnet RPC unavailable causes timeout or 5xx response
- More than 5 ERC-20 token addresses provided exceeds maxItems constraint
- Payment of 0.0015 USDC not included causes 402 Payment Required response
