How this service works
Agent-native micro APIs: hourly-refreshed feed of funded crypto bounty opportunities, GitHub repository honeypot trust scoring, live crypto spot prices and web page reading. Payment via x402 protocol (HTTP 402), USDC on Base (eip155:8453). x402 v1 and v2 compatible; instant settle via Coinbase CDP facilitator. No accounts, no API keys.
Output
Returns a JSON object containing the token symbol, wallet address queried, human-readable balance (e.g. 42.5), raw balance in smallest units (e.g. 42500000), number of decimals, the ERC-20 contract address, and the network name (e.g. 'base').
Example use cases
Verify wallet funds before payment
“Check how much USDC is in 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 on Base — I need to confirm there's enough before sending a transaction.”
Monitor DeFi portfolio token holdings
“Pull the current USDC balance for my wallet 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 on Base using the USDC contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 so I can track my holdings.”
Validate agent treasury balance
“What is the exact ERC-20 token balance, including raw units and decimals, held by address 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 on the Base network?”
Technical details
Endpoint
GEThttps://money-reactor.makar52nn2016.workers.dev/api/erc20-balance?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a fast, account-free, key-free ERC-20 balance lookup on Base network, paying only $0.001 USDC per call via the x402 micropayment protocol. Ideal for AI agents that need on-chain token balance data without API key provisioning overhead. Best for Base network queries; may not support other chains.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported network or contract address yields no result
- Wallet with zero balance returns balance: 0 rather than an error
- Payment via x402 protocol fails if USDC funds are insufficient
- Rate limits or worker downtime may cause transient 5xx errors
