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 defi-shield-hazel-vercel-app-d2538a79 -d '<json body>'
```

Example prompt: Can you analyze the token emission model and inflation risk for Uniswap — I want to know the circulating ratio, emission risk level, and whether the token supply sustainability looks moderate or concerning?

## When to prefer this

Use this endpoint when you need to evaluate a DeFi protocol's token emission health, inflation risk, or circulating supply distribution. Particularly useful when assessing whether a protocol's tokenomics are sustainable before investing or integrating. Prefer this over generic TVL endpoints when the focus is on token supply dynamics rather than liquidity alone.

## Known failure modes

- Protocol not found or unsupported — returns empty or null fields
- Market cap or FDV data unavailable from upstream sources — emission risk and circulating ratio will be null with explanatory analysis_factors
- Upstream data provider timeout — elevated response_time_ms or error
- Invalid protocol name input — may return unknown/null results

## Output

Returns a JSON object with TVL, TVL changes over 1d and 7d, token symbol, market cap, fully diluted valuation, circulating ratio estimate, emission risk classification (e.g. unknown, low, medium, high), sustainability assessment (e.g. moderate), and analysis factors explaining the assessment. Also includes response time and a data note.
