Example prompt: Before my liquidation bot interacts with this contract, scan its bytecode on Base for hidden mint functions, honeypot traps, or any rug-pull code — the contract address is 0xABC123.

## When to prefer this

Choose this endpoint when your trading bot, liquidation agent, or airdrop hunter needs rapid, pay-per-call smart contract bytecode inspection or wallet health analysis without committing to a subscription. It is well-suited for M2M automation on Base or EVM-compatible chains where the agent needs to gate actions on safety signals before executing financial transactions.

## Known failure modes

- Invalid or malformed chain identifier returns an error
- Unrecognized or non-EVM chain may not be supported
- Malformed bytecode or wallet address input causes parsing failure
- Payment of 0.30 USDC not received results in 402 Payment Required
- Rate limiting if too many calls are made in quick succession
- Contract not yet deployed or address mismatch returns no-data error

## How this service works

High-value M2M API for liquidation bots and automated funds. Analyzes wallet health factors or smart contract bytecode for hidden trap functions. Pay-per-call $0.30 USDC Base.

## Output
