## 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 orders-of-magnitude-defi-tvl-api-2d092637
```

Example prompt: What's the current total value locked across DeFi protocols? Pull the TVL data so I can see how the market is sizing up right now.

## When to prefer this

Choose this endpoint when you need quick, low-cost access to DeFi TVL metrics via a pay-per-call x402 micropayment model, especially in agent workflows where you want to avoid subscription overhead. Prefer it when you need a simple TVL snapshot rather than deep historical time-series or protocol-specific analytics.

## Known failure modes

- Payment not provided or insufficient — returns 402 Payment Required
- Invalid format parameter — may return 400 Bad Request or default format
- Data source unavailable — upstream DeFi data provider outage may cause 503 or stale data
- Rate limits if payment protocol fails to settle in time
