# Axon Smart Contract Explainer

> Axon Smart Contract Explainer is a paid API for AI agents from axiaxai.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-29).

Explains a smart contract at a given chain and address in plain language using AI, returning a human-readable breakdown of what the contract does.

## 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-6beb55f6
```

Example prompt: Can you explain what the smart contract at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain 1) actually does, in plain English?

## When to prefer this

Choose this endpoint when you need a quick, AI-generated plain-English explanation of any smart contract given only its chain ID and address. It is ideal for due diligence before interacting with unknown contracts, understanding DeFi protocols, or educating users about on-chain code — especially when you want a low-cost ($0.10 USDC) on-demand lookup without setting up your own blockchain indexing or ABI parsing infrastructure.

## Known failure modes

- Invalid or unverified contract address returns an error or empty explanation
- Unsupported chain ID results in a failure response
- Contract with no verified source code may produce a limited or low-quality explanation
- x402 micropayment failure ($0.1 USDC on Base) blocks the request
- Malformed address format causes a request error
- Newly deployed contracts not yet indexed may not resolve correctly

## 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

A JSON object containing the chain ID, contract address, and a plain-language explanation of what the smart contract does — its purpose, key functions, and behavior — generated by AI analysis of the on-chain bytecode and ABI.
