```sh
zero fetch --capability masterclaw-dev-315176a8
```

Example prompt: Give me a deep research synthesis on the likelihood of a US recession in 2025 — I want web sources, what Kalshi and Polymarket are pricing, and a structured breakdown of the key signals.

## When to prefer this

Choose this endpoint when you need a synthesized, multi-source research report that combines real-time web search with quantitative prediction-market probabilities. It is especially valuable for fast-moving topics where market odds provide a meaningful signal beyond news alone. Prefer this over a plain web search when structured, cited analysis with forecasting context is required.

## Known failure modes

- Empty or vague query returns low-quality or unfocused report
- Prediction market data unavailable for niche topics with no active markets
- Rate limits or payment failures return 402 or 429 errors
- DeepSeek reasoning latency may increase for complex multi-faceted queries
- Topics outside current web coverage may produce incomplete reports
