How this service works
EVM Token Balance Budget: checks caller-supplied raw token balance against transfer amount using only bounded caller-supplied values. Call when you need a bounded evm token balance budget result before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Token Balance Budget as versioned deterministic JSON. Price: $0.001 USDC…
Output
Returns a JSON object with a boolean 'sufficient' flag, the required_raw and available_raw amounts as strings, the shortfall_raw (zero if sufficient), a 'pass'/'fail' status, and an evidence block confirming no data is retained and no external calls were made.
Example use cases
Pre-transaction token budget gate
“I'm about to send an ERC-20 transfer that requires 800000 raw token units and my wallet shows a balance of 600000 raw units — can you check if I have enough and tell me the shortfall?”
Agent spending limit preflight
“Before my agent executes the next step, verify that a balance of 5000000 raw units covers the required cost of 3750000 raw units and confirm it's a pass.”
DeFi swap feasibility check
“I want to do a token swap that needs 1000000 raw units — my current balance is 950000 raw. Check if that's sufficient and how much I'm short by.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-token-balance-budgetWhen to prefer
Use this endpoint when an AI agent needs a deterministic, in-memory preflight check to confirm an EVM token balance covers a required spend before executing an on-chain transaction or API call — especially when privacy matters since inputs are not retained and no external calls are made. Prefer this over custom logic when you need an auditable evidence block with input hashing.
Side effects
- Missing or non-numeric amount_raw/balance_raw causes a validation error
- Strings exceeding 8192 characters are rejected
- Malformed JSON input returns a 400-level error
- Overflow or non-integer string values may cause computation failure
