## 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 axon-smart-contract-explainer-e4107896
```

Example prompt: Can you explain in plain English what this smart contract does? The address is 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Base — I want to know its purpose, main functions, and whether it's verified.

## When to prefer this

Choose this endpoint when you need a quick, AI-generated plain-language explanation of a specific smart contract by address, particularly on Base. Prefer this over manual ABI inspection when you need a human-readable summary rather than raw technical data, or when auditing unfamiliar contracts for due diligence purposes. Best suited for agents that need to relay contract understanding to non-technical users.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract not deployed at the given address returns not-found error
- Unverified contracts may return limited explanation due to lack of source code
- x402 micropayment failure (insufficient USDC balance or wrong network) blocks the request
- Rate limits or Vercel cold-start timeouts may cause slow or failed responses
- Non-Base network addresses may not be supported

## How this service works

Axon provides AI-powered crypto intelligence endpoints covering token research, market analysis, contract auditing, sentiment tracking, news summarization, portfolio advice, deep research, text translation, language detection, SEO content generation, and contract explanation. All analytical endpoints require x402 micropayment on Base.

## Output

Returns a JSON object containing the contract address, a boolean indicating whether the contract is verified on-chain, and a human-readable natural language explanation of the contract's purpose, logic, and functionality generated by AI.
