# Axon Supported Chains Lookup

> Axon Supported Chains Lookup is a paid API for AI agents from axixixia.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns a mapping of supported blockchain chain IDs to their human-readable names (e.g. Ethereum, Base)

## Facts

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 axon-supported-chains-lookup-e2137b9c
```

Example prompt: Can you fetch the list of blockchain networks that Axon supports, so I know which chain IDs are available for token research and contract analysis?

## When to prefer this

Use this endpoint when you need to discover which blockchain networks are supported by the Axon platform before making further API calls for token research, market analysis, or contract auditing. It is the canonical way to enumerate valid chain IDs for use in other Axon endpoints.

## Known failure modes

- No chains returned if service is unavailable
- 402 payment required if micropayment not provided
- Unexpected schema if new chains are added without documentation update
- Empty response if properties filter yields no matches

## 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 with a 'chains' key mapping integer chain IDs (e.g. 1, 8453) to their human-readable network names (e.g. 'Ethereum', 'Base').
