How this service works
Lists a wallet's active token approvals — which contracts can spend its tokens, the allowance, USD value at risk and a risk factor (revoke.cash-style). Essential wallet-security check for agents and users. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
Returns a list of active token approvals for the given wallet, including: the spender contract address, token name and address, current allowance amount, estimated USD value at risk, and a risk factor score (similar to revoke.cash). Helps identify dangerous or forgotten approvals that should be revoked.
Example use cases
Example prompt
“Check my wallet 0xAbc123...def for all active token approvals — I want to see which contracts can spend my tokens, how much allowance they have, and which ones are risky or have high USD value at risk.”
Technical details
Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/token-approvalsWhen to prefer
Use this endpoint when an agent or user needs to audit a wallet's ERC-20 token approval exposure — especially to identify high-risk allowances, stale permissions, or unexpected spender contracts. Preferred over manual blockchain queries when a structured, USD-valued, risk-scored response is needed without building custom indexer logic.
