# Mint Intel: Ethereum eth_call Simulator

> Mint Intel: Ethereum eth_call Simulator is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Simulates a read-only Ethereum smart contract call via eth_call and returns raw return data, decoded uint/address/string values, or the revert reason.

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 mint-intel-ethereum-eth-call-simulator-8d1c4382
```

Example prompt: Can you simulate calling the totalSupply() function (calldata 0x18160ddd) on the USDC contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet and tell me the decoded uint value?

## When to prefer this

Use this endpoint when you need to read on-chain Ethereum contract state or simulate a view/pure function call without a wallet or signing capability. It is ideal for agents that need decoded outputs (uint, address, string) without running a local Ethereum node. Prefer it over general Ethereum RPC endpoints when you want automatic ABI decoding and revert-reason extraction included in one call, and when you are specifically targeting Ethereum mainnet (not Base or other L2s, which have sibling endpoints).

## Known failure modes

- Invalid contract address format returns an error
- Malformed or empty calldata causes a decode failure
- Contract does not exist at the given address — returns empty result or revert
- Block number out of range returns an error
- Network congestion or RPC timeout may cause failure
- Incorrect ABI encoding in calldata leads to unexpected revert or garbled output

## How this service works

Simulate a read-only Ethereum contract call via eth_call - nothing is sent (?to=&data=, optional from, value, block): raw return data, first words, uint / address / string decodings, or the revert reason.

## Output

Returns a JSON object with a 'reverted' boolean, the raw hex return data, and best-effort decoded interpretations as uint, address, and string. If the call reverted, includes the revert reason string.
