## 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 parallel-search-e7ead94e -d '<json body>'
```

Example prompt: Search the web for recent breakthroughs in quantum computing using fast mode — I need results quickly.

## When to prefer this

Use this endpoint when you need real-time web search results and want control over the latency/comprehensiveness tradeoff. Choose 'fast' mode for time-sensitive queries or agentic pipelines needing low latency, and 'one-shot' for thorough research tasks. Prefer this over the async Task endpoint when you want synchronous results without polling.

## Known failure modes

- Invalid or missing query/objective — returns error indicating required field
- Invalid mode value (not 'one-shot' or 'fast') — validation error
- Payment failure or insufficient balance — 402 payment required
- Rate limiting or quota exceeded — 429 too many requests
- Network timeout for one-shot mode on complex queries — slow or no response

## How this service works

AI-powered web search

## Output

Returns web search results from Parallel Web Systems, including extracted content and relevant pages matching the query or objective. In one-shot mode results are more comprehensive; in fast mode results arrive with lower latency.
