How this service works
Ethereum native-ETH balance snapshot of up to 10 wallets that a community label dataset (brianleect/etherscan-labels, GitHub) tags as Binance, Coinbase or OKX. It is a snapshot of a sample, not total exchange reserves: no token balances, no inflow or outflow history, and the labels are community-made and may be out of date.
Output
Returns a JSON object with: the queried exchange name, a checkedAt timestamp, the number of wallets sampled, the number of wallets with a non-zero balance, the total ETH balance across the sample, and an array of individual wallet entries each with name, address, and balanceEth. Includes a note clarifying this is a community-labeled sample snapshot, not total reserves, and lists the data sources used.
Example use cases
Monitoring CEX ETH reserves by exchange
“Show me the current ETH balance snapshot for Coinbase's labeled on-chain wallets — I want to see how much native ETH they're holding across the sampled addresses.”
Comparing exchange ETH holdings
“Can you fetch the ETH wallet snapshot for Binance, OKX, and Coinbase separately so I can compare roughly how much native ETH each exchange appears to hold on-chain based on community labels?”
Quick on-chain reserve sanity check
“I'm writing a market analysis — pull me the community-labeled OKX Ethereum wallet ETH balances so I have a rough sense of their on-chain native ETH position right now.”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/cex-exchange-reserve-flows?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, lightweight on-chain ETH balance snapshot for community-labeled Binance, Coinbase, or OKX wallets without needing full reserve accounting, token balances, or historical flow data. Prefer this over full blockchain analytics platforms when cost, speed, and simplicity matter more than completeness. Not suitable for compliance, auditing, or precise reserve verification.
Side effects
- Invalid exchange name returns an error or defaults to binance
- Community labels may be outdated, causing incorrect wallet attribution
- Only up to 10 wallets sampled — does not represent total exchange reserves
- Public Ethereum RPC node may be slow or temporarily unavailable, causing timeouts
- No token balances or flow history available — only native ETH snapshots
