How this service works
Returns the native token balance (ETH, POL, BNB) for any EVM wallet address. Supports Ethereum, Base, Polygon, Arbitrum, Optimism, and BSC. Includes optional USD value. $0.002/call — 60% below comparable market rate. Free upstreams: DRPC + CoinGecko, no API key required.
Output
Returns the native token balance of the queried wallet address on the specified EVM-compatible network. If with_usd is true, also returns the live USD equivalent of the balance, fetched at query time.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/wallet-balanceWhen to prefer
Use this endpoint when you need a quick, no-account, pay-per-call native token balance check for any EVM-compatible wallet across Ethereum, Base, Polygon, Arbitrum, Optimism, or BSC. Prefer it over block explorer APIs when you want micropayment-gated access without API key management, or when building autonomous agents that need on-chain balance data on-demand.
Side effects
- Invalid or malformed wallet address (not 0x-prefixed or not 42 characters) returns an error
- Unsupported network value returns a validation error
- Address with no on-chain history may return a zero balance
- Live USD price fetch failure may cause with_usd=true requests to fail or return null for USD value
- Rate limiting or upstream RPC node unavailability may cause transient errors
- Payment failure (insufficient USDC or bad x402 header) results in 402 response
