## 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 vape-market-intelligence-scanner-219643d4
```

Example prompt: Pull a live market intelligence snapshot for the Base ecosystem — I want to see current TVL, top protocols by share, 24h gainers and losers, the fear and greed index, and any concentration risk flags.

## When to prefer this

Choose this endpoint when you need a broad, ecosystem-level market intelligence view of Base DeFi — covering TVL, protocol rankings, sentiment, and risk concentration in a single call. Prefer this over single-protocol scanners or security audit endpoints when the goal is macro market context rather than per-contract vulnerability detection.

## Known failure modes

- Missing or invalid address parameter returns a 4xx error
- Unsupported chain ID override may return empty or error response
- Upstream DeFi data source outage may result in stale or incomplete TVL data
- Rate limits or payment failures via x402 protocol may block access
- Response may lag real-time by minutes depending on indexer refresh cadence

## How this service works

VAPE market_intel — Base TVL with 24h/7d change, per-protocol share/category breakdown, concentration risk, 24h DEX volume, top gainers/losers, ETH/BTC prices, Fear & Greed index, global market cap, and a real-data narrative summary. Takes no input -- always a whole-of-Base snapshot, not a per-token lookup. Real on-chain/market data, no simulation.

## Output

A JSON object containing: BTC and ETH spot prices, fear/greed index value and classification, Base total TVL and 24h change percentage, top protocols ranked by TVL with category and 24h change, top 24h gainers and losers, DEX volume for 24h, global market cap and 24h change, category breakdown percentages (e.g. Lending, Dexes), a concentration risk label (LOW/MEDIUM/HIGH with detail), and a human-readable market overview narrative string.
