## 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-buyer-side-product-api-finder-ae0ddca7 -d '<json body>'
```

Example prompt: I need to find the best PDF text extractor API available — can you route my request through VIA and get a recommendation with alternatives, searching across services and information markets?

## When to prefer this

Use VIA Router when an AI agent or user needs to quickly identify and compare APIs, SaaS tools, or data services for a given task without manually searching marketplaces. It is especially valuable when the agent lacks prior knowledge of what services exist in a domain, needs a buyer-side recommendation (not just a search result), and can pay $0.01 USDC per query via x402 on Base. Prefer this over raw web search when you want structured, source-attributed product recommendations with alternatives.

## Known failure modes

- Intent too vague or short (minLength: 2) — returns routing error
- Invalid market enum value — returns validation error
- Invalid country code (must be ISO 3166-1 alpha-2) — returns 400
- Payment failure or insufficient USDC balance — x402 payment not settled, call rejected
- No matching product found for intent — returns empty alternatives array with null recommendation
- Unsupported language requested — returns validation error

## How this service works

VIA is a paid buyer-side router for AI agents and humans. Compare APIs, services, products and sourced research with x402 USDC payments on Base.

## Output

Returns a JSON object with a recommended product or service title and its source, a list of alternative options, confirmation that payment was made (paid: true), the settlement network and transaction hash on Base, and the toll amount in USD ($0.01). The recommendation is grounded in sourced research across APIs, services, and products matching the stated intent.
