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 saylor-innovations-defi-capital-flows-7-day-tvl-movers-fdf23ad2
```

Example prompt: Show me which DeFi protocols gained or lost the most TVL over the last 7 days — I want to see the top movers in both directions.

## When to prefer this

Choose this endpoint when you need a quick, ranked summary of DeFi protocol capital flow movements over a 7-day window without needing to query individual protocol data or on-chain sources yourself. It is ideal for trend monitoring, weekly DeFi briefings, and portfolio risk checks where knowing relative TVL momentum across protocols matters more than granular block-level data.

## Known failure modes

- No input object provided — returns 400 validation error
- Upstream DeFi data source unavailable — may return 503 or stale data
- Payment not fulfilled (x402) — returns 402 Payment Required
- Rate limiting if called excessively in short windows
- Empty gainers/losers arrays if no significant TVL movement detected in the period
