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 containing the original approval_raw and threshold_raw values, a boolean field 'infinite_or_near' indicating whether the approval is infinite or near-infinite, an advisory status, an operation identifier, and evidence metadata including whether the input was retained (always false), the SHA256 hash of the input, and the number of external calls made (always 0).
Example use cases
Pre-transaction approval safety check
“I'm about to sign an EVM transaction and the approval_raw is 115792089237316195423570985008687907853269984665640564039457584007913129639935 — can you check if that's an infinite or near-infinite approval compared to a threshold of 115792089237316195423570985008687907853269984665640564039457584007913129000000?”
DeFi agent preflight risk screening
“My DeFi agent is about to interact with a smart contract. The raw approval value is 100000000000000000000000000000000000000000000000000000000000000000000000000000 and I want to know if it crosses into infinite-approval territory — use a threshold of 115792089237316195423570985008687907853269984665640564039457584007913129000000.”
Wallet security audit for unlimited allowances
“Can you scan this approval amount — 79228162514264337593543950335 — and tell me whether it counts as infinite or near-infinite based on a threshold of 115792089237316195423570985008687907853269984665640564039457584007913129000000? I want to flag any dangerous unlimited allowances in my wallet.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-infinite-approval-flag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or DeFi workflow needs a fast, verifiable, stateless check on whether an EVM token approval amount is infinite or near-infinite before executing a transaction. It is ideal for preflight safety screening in autonomous agent pipelines where no signup or API key management is desired and pay-per-result micropayment billing via x402 is acceptable. Prefer this over on-chain checks when you want a quick off-chain advisory result with cryptographic input evidence (SHA256 hash) and guaranteed no data retention.
Side effects
- Invalid or non-numeric approval_raw causes a parsing error
- Missing required fields returns a validation error
- approval_raw or threshold_raw exceeding 8192 characters returns a size limit error
- Malformed JSON input returns a 400 error
- Payment failure (insufficient USDC or wrong network) blocks the request via x402
