## How to call it through Zero

```sh
zero fetch --capability aurenic-ethereum-address-validator-0fceeda8
```

Example prompt: Can you check if 0x742d35Cc6634C0532925a3b8D4C9B9A73d5B4f21 is a valid Ethereum address with correct EIP-55 checksumming?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call Ethereum address validation without spinning up a full Web3 library. Ideal for agent pipelines that need to sanitize user-submitted addresses before executing transactions, storing wallet data, or interacting with smart contracts. At $0.001 per call, it is cost-effective for high-frequency validation workflows.

## Known failure modes

- Malformed or non-hex address string returns a validation failure or error response
- Missing 0x prefix may cause a failed validation or parsing error
- Empty address parameter results in a 400-level error
- Non-Ethereum addresses (e.g. Bitcoin, Solana) will fail validation as they do not match ETH format

## How this service works

Web scraping and AI automation. High-performance data extraction and pay-per-call microservices.

## Output

Returns a JSON response indicating whether the provided Ethereum address passes format validation and EIP-55 checksum verification, confirming if the address is valid or flagging any formatting issues.
