## 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 api-deepbluebase-xyz-2555dde0
```

Example prompt: What's the current market sentiment, RSI, momentum direction, and fear/greed index for BTC, ETH, SOL, and XRP — are we in a trending or neutral regime?

## When to prefer this

Use this endpoint when you need a multi-signal, pre-aggregated crypto sentiment snapshot across BTC/ETH/SOL/XRP in a single cheap call ($0.03), especially compared to subscribing to Santiment ($249/mo) or Coinalyze ($29/mo). Best for agents that need a quick market regime read with RSI + fear/greed + momentum combined, rather than building their own indicator pipeline.

## Known failure modes

- Payment not included or insufficient — 402 Payment Required
- Upstream data source unavailable — partial or stale data returned
- Rate limiting if called too frequently
- No query parameters accepted; malformed request returns 400

## How this service works

Premium crypto sentiment bundle — sentiment scores, funding rates, liquidation data, and open interest across BTC/ETH/SOL/XRP

## Output

Returns an array of per-coin objects (BTC, ETH, SOL, XRP) each with RSI, composite_score, label (neutral/bullish/bearish), regime (trending/neutral), momentum value, direction (UP/DOWN), and confidence score. Also returns an overall summary with aggregate composite_score, fear_greed_index (0-100), and fear_greed_label. Includes data source attribution and timestamp.
