## 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-963977e0 -d '<json body>'
```

Example prompt: Do a deep research dive on the current state of solid-state battery commercialization — who are the leading companies, what are the main technical hurdles, and what does the funding landscape look like? Use exhaustive research effort.

## When to prefer this

Choose this endpoint when you need synthesized, multi-source research rather than a single web page scrape. It is especially useful when the user's question requires aggregating information across many sources, forming a holistic answer, or conducting background research on a company, technology, or topic. Prefer it over simple search APIs when depth and synthesis matter more than raw speed. The adjustable research_effort parameter makes it suitable for both quick lookups (lite) and exhaustive academic-style research (exhaustive).

## Known failure modes

- Input question exceeds 40,000 character limit — request is rejected
- Invalid research_effort enum value — validation error
- Payment not completed or insufficient USDC balance — 402 Payment Required
- Underlying web search or content extraction fails — partial or empty results
- Exhaustive research effort may time out for very broad questions
- Rate limiting or quota exceeded on upstream search providers

## How this service works

## Output

A structured research report synthesizing information gathered from multiple web sources, containing findings, summaries, and relevant facts related to the input research question. The depth and breadth of the report scales with the chosen research_effort level (lite, standard, deep, or exhaustive).
