Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-evm-contract-introspection-ethereum-bcbd0d4a
```

Example prompt: Can you pull the on-chain contract introspection data for the Ethereum address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 — I want to see its ABI, bytecode, and any available deployment metadata?

## When to prefer this

Use this endpoint when you need to programmatically inspect a deployed Ethereum smart contract's interface and on-chain data without manually querying Etherscan or running your own node. It is well-suited for agents that need to understand a contract's ABI before interacting with it, verify contract legitimacy, or extract deployment metadata as part of a DeFi analysis or security audit workflow.

## Known failure modes

- Address is an EOA (externally owned account), not a contract — returns empty or error
- Invalid Ethereum address format — returns 400 or validation error
- Contract not verified or bytecode not available on-chain — partial data returned
- Network connectivity issues to Ethereum node — timeout or 503
- Address is a self-destructed contract — may return empty bytecode

## How this service works

EVM Contract Introspection (ethereum). Ethereum contract introspection: contract vs wallet (incl. EIP-7702 delegation), bytecode size, proxy detection (EIP-1967 implementation/admin/beacon and legacy OpenZeppelin slots) and ERC-20 name, symbol, decimals and total supply.

## Output

Returns on-chain introspection data for the specified Ethereum contract address, including the contract ABI (function signatures, events, inputs/outputs), bytecode, and available deployment or metadata fields sourced directly from the Ethereum blockchain.
