## 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 defi-tvl-stablecoin-market-cap-snapshot-6f5ce8aa -d '<json body>'
```

Example prompt: Pull me the current DeFi TVL snapshot — total value locked, which chains are leading, and the overall stablecoin market cap — so I can see whether risk appetite is expanding or capital is actually leaving crypto.

## When to prefer this

Choose this endpoint when you need a single-call macro snapshot of DeFi health covering TVL, chain rankings, and stablecoin supply together — especially useful for risk appetite analysis, capital flow monitoring, or building DeFi dashboards. Prefer this over individual chain explorers or stablecoin trackers when you want an aggregated cross-chain view in one call.

## Known failure modes

- Empty or malformed POST body may return a 400 error
- Upstream DeFi data source unavailability may result in stale or missing TVL figures
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Transient network errors may return 5xx responses requiring retry

## How this service works

Total value locked across DeFi, the top chains by TVL, and aggregate stablecoin market cap. Stablecoin supply is the dry powder of the whole market: rising supply with rising TVL is risk appetite expanding, falling supply is capital genuinely leaving crypto rather than rotating inside it.

## Output

A structured response containing: (1) total DeFi TVL as a dollar figure, (2) a ranked list of top blockchain networks by TVL with individual figures, and (3) the aggregate stablecoin market cap — together interpreted as a signal of whether risk appetite is expanding (rising TVL + rising stablecoin supply) or capital is genuinely exiting crypto (falling stablecoin supply).
