## 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 payweave-parallel-agentic-web-search-4af88584 -d '<json body>'
```

Example prompt: Search the web and give me a structured research report on the current state of solid-state battery commercialization — include key players, recent breakthroughs, and market timelines, with citations for everything.

## When to prefer this

Choose this endpoint when you need agentic, multi-step web research that returns structured, cited results rather than a raw web search listing. It is especially suited for tasks requiring synthesis across multiple sources, custom output schemas via task_spec, or integration with MCP servers. Prefer it over simple search APIs when you need organized, citation-backed output rather than a list of links.

## Known failure modes

- Missing required 'input' field returns a validation error
- Missing required 'processor' field causes task rejection
- Invalid or unrecognized processor identifier results in an error response
- Web sources unavailable or blocked by source_policy may yield incomplete results
- Task timeout for complex multi-step research queries
- Webhook delivery failure if webhook URL is unreachable
- Rate limiting if too many concurrent calls are made

## How this service works

Agentic web search and structured research.

## Output
