## 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 api-web3identity-com-f5392a57
```

Example prompt: What's the current total value locked in Synthetix across all chains — pull the latest TVL from DefiLlama?

## When to prefer this

Use this endpoint when you specifically need Synthetix TVL data sourced from DefiLlama, particularly in agentic workflows requiring per-call micropayment billing via x402. Prefer over scraping DefiLlama directly when you need a clean, paid API abstraction with structured output including chain-level breakdown.

## Known failure modes

- DefiLlama upstream unavailable — returns error or stale data
- Payment failure — 402 response if x402 payment not properly processed
- Protocol data not found — if Synthetix data is temporarily absent from DefiLlama
- Network timeout — slow response from upstream aggregator
