> PayWeave Parallel Web Search API is a paid API for AI agents from parallel.payweave.services, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

## 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-web-search-api-e190b2a2 -d '<json body>'
```

Example prompt: Search the web for me on the topic of 'AI regulation in Europe 2024' — run up to 3 queries covering recent legislation, enforcement actions, and industry reactions, and give me the top 10 results with titles and excerpts.

## When to prefer this

Use this endpoint when you need structured, multi-query web search results with excerpts and publication dates returned in a machine-readable format, especially in agentic pipelines where pay-per-call pricing via x402/USDC is acceptable and you need to run several related queries under a single research objective.

## Known failure modes

- Missing required fields (objective or search_queries) returns a validation error
- Invalid mode enum value causes a spec_validation_warning or rejection
- max_results set too high may be capped or trigger a warning
- Payment failure via x402 protocol prevents the call from executing
- Malformed search_queries array returns an input_validation_warning
- No results found for obscure queries returns an empty results array

## How this service works

Agentic web search and structured research.

## Output

Returns a search_id, an array of results each containing a URL, title, text excerpts, and publish date, plus optional usage counts and any input/spec validation warnings.
