How this service works
Live native-asset wallet balance lookup across 6 chains (Bitcoin, Ethereum, Base, Solana, TRON, Ronin) via public RPCs. One call returns the current balance as JSON. No API key, no signup — x402 per-call payment only.
Output
A JSON object containing the current native-asset balance for the specified wallet address on the requested blockchain, fetched live via public RPC nodes.
Example use cases
DeFi portfolio balance check
“Can you look up the current ETH balance for wallet address 0x4838B106FCe9647Bdf1E7877BF73cE8B0BAD5f97 on Ethereum?”
Solana airdrop eligibility check
“Check the current SOL balance for the wallet address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM on Solana — I need to know if it qualifies for a minimum balance requirement.”
Bitcoin cold wallet verification
“Look up the native BTC balance for the Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — I want to confirm funds arrived.”

Choose this endpoint when you need a lightweight, real-time native-asset balance check for a single wallet address on one of the six supported chains (Bitcoin, Ethereum, Base, Solana, TRON, Ronin) without setting up an API key or account. It is ideal for spot-checks, verification workflows, or agent pipelines that pay per call via x402. Prefer alternatives if you need token balances (ERC-20, SPL, etc.), historical balances, multi-address batch lookups, or chains outside the supported set.
Side effects
- Invalid or malformed wallet address for the given chain returns an error or empty result
- Unsupported chain value (not one of btc, eth, base, sol, tron, ronin) results in a validation error
- Public RPC node downtime or rate limiting may cause transient failures or stale data
- Payment failure via x402 protocol blocks the request entirely
- Address format mismatch (e.g. EVM address passed for BTC chain) may cause an error or zero balance
