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 tokenguard-chains-endpoint-44927839 -d '<json body>'
```

Example prompt: Can you pull the full list of blockchain networks available in the TokenGuard DeFi API, including their TVL in USD and chain IDs?

## When to prefer this

Use this endpoint when you need to discover which blockchain networks are available in the TokenGuard ecosystem before querying chain-specific DeFi data, or when you need a comprehensive multi-chain TVL overview. Prefer this over alternatives when you need chain IDs for downstream TokenGuard API calls or want a single source of truth for supported networks.

## Known failure modes

- Payment failure: x402 micropayment of $0.005 USDC on Base not sent or rejected
- Service unavailable: Hugging Face Space is sleeping or cold-starting
- Empty response: no chains data available at time of call
- Rate limit: too many requests in short period

## How this service works

Blockchain TVL overview — all 469+ chains ranked by total value locked with token symbol and chain ID (DeFiLlama, free, no key).

## Output

A JSON object containing an array of blockchain networks, each with name, symbol, TVL in USD, and chain ID, plus a total_chains count (example shows 469 chains including Ethereum at ~$78B TVL).
