How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing a wallet_allowance_exposure field with an exposure assessment, a list of warnings, an evidence_scope indicating the data source is caller-supplied, and a full receipt with payment and execution metadata including request/execution IDs, payment details, and a result hash.
Example use cases
DeFi wallet security audit
“I want to check my wallet's token allowances for any suspicious or unlimited approvals that could be drained — here's the raw allowance data from my wallet, can you tell me what's risky?”
Post-hack allowance triage
“My wallet might have been compromised. Can you analyze these wallet allowance records and flag which ones look like high-exposure risks I need to revoke immediately?”
Pre-transaction approval review
“Before I proceed, can you evaluate these token approvals I've been asked to sign and tell me what level of allowance exposure they represent and whether there are any warnings?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/wallet_allowance_exposure/invokeWhen to prefer
Choose this endpoint when you need a quick, paid, agent-native analysis of wallet token allowance exposure from structured or semi-structured allowance data. It is purpose-built for AI agents operating in DeFi or Web3 contexts where evaluating spending permissions and approval risks is required before or after transactions. Prefer it over generic smart contract auditors when the focus is specifically on allowance-level risk rather than full contract code analysis.
Side effects
- Empty or malformed wallet_allowance_request input returns an error
- Input below 2 characters or above 65536 characters fails schema validation
- Ambiguous or incomplete allowance data may produce low-confidence or empty warnings
- Network or payment settlement failures on Base (eip155:8453) may cause execution errors
- Malformed JSON in the allowance request may cause parsing failures
