## 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 spipe-research-api-589af804 -d '<json body>'
```

Example prompt: Do a deep research dive on the competitive landscape of AI coding assistants — who are the main players, their pricing, and key differentiators. Use exhaustive effort so I get a thorough answer.

## When to prefer this

Choose this endpoint when you need a synthesized, multi-source research answer rather than a single web page or search result list. It is well-suited for complex questions requiring content extraction and synthesis across many sources, especially when you can tune the effort level from quick lite lookups to exhaustive deep dives. Prefer this over raw search APIs when you want a ready-to-use answer, not raw links.

## Known failure modes

- Input question exceeds 40,000 character limit — request rejected
- Invalid research_effort enum value — request rejected
- Payment not received or insufficient USDC — 402 error returned
- Upstream web search or content extraction failure — partial or empty results
- Timeout on exhaustive research tasks — may return incomplete synthesis

## How this service works
