# defi.hugen.tokyo Bridge Token List

> defi.hugen.tokyo Bridge Token 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).

Lists all tokens available for cross-chain bridging on a specific chain, including addresses, symbols, decimals, and bridge compatibility.

## Facts

- Endpoint: GET https://defi.hugen.tokyo/defi/bridge/tokens

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-dbe1728a
```

Example prompt: Show me all the tokens I can bridge on Arbitrum — I need their contract addresses, symbols, and decimals to figure out what assets are available for cross-chain transfers.

## When to prefer this

Use this endpoint when you need to discover which tokens are supported for cross-chain bridging on a specific blockchain before constructing a bridge route or swap. Ideal as a prerequisite step before querying bridge quotes to validate token availability.

## Known failure modes

- Invalid or unsupported chain key returns empty list or 400 error
- Chain key not recognized returns error response
- Payment failure (402) if USDC payment not provided
- Rate limiting if too many requests made
- Network timeout for slow chain data retrieval

## How this service works

List all tokens available for cross-chain bridging on a specific chain — token addresses, symbols, decimals, and bridge compatibility. Filter by chain key. Accepts USDC payments on Base and Solana

## Output

A list of tokens available for cross-chain bridging on the specified chain, including each token's contract address, symbol, decimal precision, and which bridge protocols support it.
