How this service works
Tollex lets software agents buy APIs and tools under rules you set: it finds a capability that fits, checks your policy before anything is signed, pays with x402 in USDC on Base or USDG on Robinhood Chain, reconciles uncertain payments and returns a signed receipt.
Output
Returns the native token balance (e.g. ETH, gas token) held at the specified EVM wallet address, expressed as an on-chain value. The response includes the balance amount for the queried address, confirmed via a signed receipt from the Tollex payment and reconciliation layer.
Example use cases
Pre-transaction funding check
“Before I send that transaction, can you check whether 0x4e83362442b8d1bec281931b9e6e61be9b5a4321 actually has enough native tokens to cover it?”
Agent treasury monitoring
“What's the current native balance on our agent's operating wallet at 0xAbCd1234567890abcdef1234567890abcdef1234 — I want to make sure it hasn't run dry?”
Auditing a counterparty wallet
“Look up the native on-chain balance for the address 0xDeAdBeEf00000000000000000000000000000000 — I want to verify they have funds before we proceed with the deal.”
Technical details
Endpoint
POSThttps://api.tollex.org/tools/wallet_native_balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a quick, pay-per-use native token balance lookup for any EVM wallet address without requiring a dedicated RPC node setup. Ideal for agents that only occasionally need balance checks and want to pay micropayments via x402/USDC rather than maintaining API subscriptions. Prefer this over self-hosted RPC calls when operating under policy-controlled agent spending rules on the Tollex platform.
Side effects
- Invalid or malformed address (not matching ^0x[0-9a-fA-F]{40}$) returns a validation error
- Payment failure or insufficient USDC for the $0.0078 per-call fee results in a 402 response
- Address is valid but has zero balance — returns 0 rather than an error
- Network or RPC timeout causes a retrieval failure
- Uncertain payment reconciliation may delay receipt delivery
