## 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-chain-tvl-lookup-ca996582 -d '<json body>'
```

Example prompt: What is the current total value locked on Arbitrum? Pull the chain TVL from TokenGuard.

## When to prefer this

Use this endpoint when you need on-chain TVL data for a specific blockchain as part of DeFi research, ecosystem comparison, or portfolio analysis. Prefer this over general market data APIs when you specifically need TVL (locked capital) rather than price or volume data. Best suited for agents building DeFi dashboards or conducting chain-level analytics.

## Known failure modes

- Unsupported or unrecognized chain name returns an error or empty result
- Network or upstream data provider outage returns a 5xx error
- Missing or malformed chain identifier in request body causes a 400 error
- Rate limiting or x402 payment failure blocks the request
- Stale or delayed data if upstream DeFi data provider has lag
