## 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-supported-chains-list-e767c01e
```

Example prompt: What blockchains does Axon support? I need to know which chain IDs and network names are available before I run a token research query.

## When to prefer this

Use this endpoint when you need to enumerate all blockchain networks supported by Axon before making token research, market analysis, or contract auditing calls — useful for validating chain parameters or presenting network options to a user.

## Known failure modes

- Missing or invalid x402 micropayment header returns 402 Payment Required
- Service unavailable returns 500 error
- Empty or malformed properties filter may return unexpected results

## 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
