How this service works
Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.
Output
Returns a verdict (clean, medium, high, critical, etc.), a summary count of active/unlimited/EOA-spender approvals, and a detailed list of each risky approval including the token symbol, spender address, whether the spender is a contract or EOA, the allowance and realistic drainable exposure, and one or more risk flags — all computed live from Base chain at the current block height.
Example use cases
Example prompt
“Can you audit my Base wallet 0xAbc123...def for risky ERC-20 approvals — I want to know if any contracts or EOA addresses have unlimited or high-risk allowances to drain my tokens?”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/approvalsWhen to prefer
Choose this endpoint when you need a live, trustless, on-chain-only approval audit for a Base wallet with no reliance on third-party databases — especially when you want manipulation-resistant data or need to programmatically assess drainer risk (EOA spenders, unlimited allowances) before executing a DeFi transaction or after a suspected phishing event.
Side effects
- Missing required 'wallet' parameter returns validation error
- Invalid or non-checksummed wallet address may return error or empty result
- Lookback window exceeding 800 blocks is clamped or rejected
- No approvals found in the lookback window returns verdict 'no_recent_approvals'
- RPC or chain connectivity issues may cause timeout or unknown verdict
- Payment of $0.01 USDC via x402 required; unpaid requests return 402
