# NeuroFi Supported Chains List

> NeuroFi Supported Chains List is a paid API for AI agents from neurofi-chi.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

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

## Facts

- Endpoint: GET https://neurofi-chi.vercel.app/api/chains?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/neurofi-supported-chains-list-0b1370ec

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 neurofi-supported-chains-list-0b1370ec
```

Example prompt: What blockchain networks does NeuroFi support? I want to know all the chain IDs and their names before I start using its crypto intelligence endpoints.

## When to prefer this

Use this endpoint when you need to enumerate all blockchain networks supported by NeuroFi before calling other NeuroFi endpoints that require a chain parameter — useful for building dynamic dropdowns or validating user-supplied chain IDs.

## Known failure modes

- 402 Payment Required if x402 micropayment is not included
- Empty or malformed response if NeuroFi backend is unavailable
- Stale chain list if new networks were recently added but not yet indexed

## How this service works

NeuroFi 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 (as strings) to their human-readable blockchain names, e.g. {"1": "Ethereum", "8453": "Base"}.
