# defi.hugen.tokyo Bridge Chains List

> defi.hugen.tokyo Bridge Chains List is a paid API for AI agents from defi.hugen.tokyo, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a list of all blockchain networks supported for cross-chain bridging, including chain IDs, names, and native token information for 30+ chains.

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 defi-hugen-tokyo-a3aaa5ce
```

Example prompt: What blockchain networks are available for cross-chain bridging — can you list all supported chains with their chain IDs and native token info?

## When to prefer this

Use this endpoint when you need to discover or validate which blockchain networks are supported before constructing a bridge route, or when building a chain selector UI. It is a prerequisite step before querying bridge routes or quotes, as it provides canonical chain IDs and native token metadata for all supported networks.

## Known failure modes

- Payment failure (402): USDC payment on Base or Solana was not accepted or insufficient
- Service unavailable (5xx): upstream provider temporarily down
- Empty or truncated response if data exceeds size limits

## How this service works

List all blockchain networks supported for cross-chain bridging — 30+ chains with chain IDs, names, and native token info. Accepts USDC payments on Base and Solana

## Output

A list of 30+ blockchain networks supported for cross-chain bridging, each entry including the chain ID, human-readable chain name, and native token details (symbol, name, decimals). Useful for populating chain selectors, validating chain support, or building bridge routing logic.
