How this service works
Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents
Output
Returns a JSON object containing the blockchain network name, the observed token balance for the queried address, and the timestamp at which the balance was recorded on-chain.
Example use cases
DeFi portfolio balance check
“What's the current on-chain token balance for my wallet 0x1234...abcd on Base — I want to see how many USDC tokens I'm holding right now.”
Automated treasury monitoring
“Check the token balance for our DAO treasury wallet 0xDEAD...BEEF on Base and alert me if it drops below 10,000 tokens.”
Verify airdrop receipt
“Can you confirm whether wallet 0xAaaa...Bbbb received any tokens on the Base network? I'm trying to verify an airdrop landed correctly.”
Technical details
Endpoint
GEThttps://cryptoshark.duckdns.org/chain/token-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, pay-per-call on-chain token balance lookup on supported networks (especially Base) without needing to run your own node or pay for a premium RPC subscription. Ideal for autonomous agents that need occasional balance checks at $0.001 per call via x402 micropayments.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported network identifier causes a rejection
- Contract address not found on the specified network
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Stale or delayed data if the chain is experiencing congestion
