## 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 scope-research-api-product-research-c413c596 -d '<json body>'

Example prompt: Can you research the Sony WH-1000XM5 headphones by Sony, focusing on noise cancellation performance? I need source-backed findings from the public web.

## When to prefer this

Choose this endpoint when you need cited, source-backed web research on a specific product rather than a generic web search. It is optimized for AI agent consumption via x402 micropayments, making it suitable for automated pipelines that require structured, trustworthy product intelligence without managing a full browser or search API integration.

## Known failure modes

- Missing required 'product' field returns a validation error
- Payment not provided or insufficient USDC via x402 returns a 402 Payment Required response
- Unknown or very niche product may return sparse or low-confidence results
