## 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 solana-defi-overview-tvl-protocols-stablecoins-dex-volume-fees-8e208e18 -d '<json body>'
```

Example prompt: Can you pull up a full Solana DeFi overview for me — TVL trend, top protocols by TVL, stablecoin stats, DEX trading volume, and fee data all in one shot?

## When to prefer this

Choose this endpoint when you need a broad, multi-metric Solana DeFi snapshot in a single call rather than querying individual protocol APIs separately. It aggregates TVL, DEX volume, stablecoins, and fees together, making it ideal for dashboards, research reports, or investment analysis workflows where breadth matters over per-protocol depth.

## Known failure modes

- Upstream DeFi data provider unavailable, returning empty or error response
- Stale data if on-chain indexers are lagging behind current blockchain state
- Payment failure via x402 protocol resulting in 402 response before data is returned
- Partial data if some sub-metrics (e.g. fees) are temporarily unavailable from the source
