How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the balance is sufficient (boolean), the required and available amounts in raw units, the shortfall (0 if sufficient), a pass/fail status, and a tamper-evident evidence block including input SHA-256 hash and confirmation that no data was retained and no external calls were made.
Example use cases
Pre-trade token sufficiency check
“I'm about to execute a DeFi swap that requires 5000000 raw token units — can you verify whether my current balance of 4200000 raw units is enough, and tell me the shortfall if it's not?”
Agent payment preflight guard
“Before my agent submits an on-chain payment of 1000000 raw USDC, check if the wallet balance of 2500000 raw units covers it so we don't waste gas on a doomed transaction.”
Budget validation for multi-step workflow
“My automated workflow needs 750000 raw tokens for the next step — verify that my available balance of 800000 raw units is sufficient before we proceed.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-token-balance-budget?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, privacy-preserving, verifiable computation to check whether an EVM token balance covers a required spend amount before committing to a blockchain transaction. Prefer this over on-chain balance reads when you already have the raw values in memory and need a fast, auditable preflight result with cryptographic evidence of non-retention. It is especially useful for AI agents orchestrating DeFi workflows or on-chain payments that need a trustless sanity check without storing sensitive financial data.
Side effects
- Malformed or non-numeric string values for amount_raw or balance_raw may cause a validation error
- Excessively large strings beyond the 8192 character limit will be rejected
- Missing required fields returns an error response
- Network or payment (x402) issues may prevent the call from completing
