How this service works
EVM Infinite Approval Flag: EVM Infinite Approval Flag flags an approval at or near a caller-supplied maximum uint threshold from bounded caller-supplied values without an external provider. Call EVM Infinite Approval Flag 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 Infinite Approval Flag as versioned determini…
Output
Returns a JSON object with a boolean 'infinite_or_near' field indicating whether the approval meets or exceeds the threshold, plus the schema version, operation name, advisory status, and an evidence block containing a SHA-256 hash of the input and confirmation that no data is retained and no external calls were made.
Example use cases
Pre-transaction safety check
“Before I sign this token approval transaction, check if the raw approval value 115792089237316195423570985008687907853269984665640564039457584007913129639935 is infinite or near-infinite compared to the threshold 1000000000000000000000000000000.”
DeFi protocol audit
“I'm auditing a DeFi protocol and need to know if the allowance 115792089237316195423570985008687907853269984665640564039457584007913129639935 qualifies as an infinite approval — use threshold 115792089237316195423570985008687907853269984665640564039457584007913129000000.”
Wallet risk dashboard flagging
“For our wallet risk dashboard, flag whether the on-chain approval raw value 79228162514264337593543950335 should be considered infinite given a threshold of 10000000000000000000000000000.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-infinite-approval-flagWhen to prefer
Use this endpoint when you need a fast, stateless, in-memory check of whether a raw EVM token approval value is effectively unlimited (infinite or near-infinite) relative to a given threshold — particularly for pre-transaction preflight checks or security audits. It is preferable to rolling your own big-integer comparison because it provides an evidence trail (SHA-256 of input, no-retention guarantee, zero external calls) suited for governed agent workflows.
Side effects
- Invalid or non-numeric approval_raw or threshold_raw values may cause a parse error
- Strings exceeding the 8192-character maxLength will be rejected
- Missing required fields returns a validation error
- Very large numeric strings that cannot be parsed as big integers may fail
