## 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 via-router-product-search-7e3983e9 -d '<json body>'
```

Example prompt: Can you find me the best service for extracting text from PDFs — search the services market and give me a recommendation with alternatives?

## When to prefer this

Choose this endpoint when an AI agent or human needs a buyer-side recommendation for a product, API, or service given a plain-language intent, and wants curated sourced results rather than raw web search. It is especially useful when the agent needs to compare options across categories (services, commerce, information, travel) and can pay $0.01 USDC per query via x402 on Base. Prefer this over generic web search when you want structured, actionable recommendations with alternatives rather than unstructured links.

## Known failure modes

- Intent too vague or too short (minLength: 2 enforced) — returns validation error
- Unsupported market enum value — returns schema validation error
- Invalid country code (not ISO 3166-1 alpha-2) — returns pattern validation error
- No suitable recommendation found — alternatives list may be empty
- Payment failure on Base network — settlement not completed, request not fulfilled
- Service unavailable or upstream data source unreachable
