## 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-arbitrum-4d0b91be
```

Example prompt: Can you pull up the on-chain contract details for the Arbitrum address 0x912CE59144191C1204E64559FE8253a0e49E6548 — I want to inspect what's deployed there?

## When to prefer this

Choose this endpoint when you specifically need smart contract introspection data on the Arbitrum (L2) network and want a simple pay-per-call REST API without managing your own Arbitrum RPC node or Etherscan API keys. Prefer it over direct RPC calls when you want a managed, metered service with x402 micropayment support.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Address is an EOA (externally owned account) rather than a contract, returning empty or minimal data
- Contract not deployed on Arbitrum network returns not-found response
- Network or RPC node connectivity issues may cause timeouts
- Rate limiting if called too frequently

## How this service works

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

## Output

Returns on-chain contract introspection data for the specified Arbitrum EVM address, which may include contract bytecode, ABI, deployment details, contract type, and other metadata retrievable from the Arbitrum network for that address.
