# 电商选品

Check demand and pricing for a product idea across marketplaces and social trends before deciding what to sell.

**When to use:** The user is choosing products, markets or price points as a seller.

Requires the `agentrouter` skill (or the AgentRouter MCP server at `http://localhost:3000/api/mcp`) and the `AR_KEY` environment variable.

## Capabilities

- `api/commerce.price`

Inspect a capability before the first call: parameters and prices are listed there.

## Steps

1. Search listings and prices for the product.
2. Check social interest (小红书 notes, TikTok Shop) for demand signals.
3. Recommend go / no-go with price range and evidence.

## Cost

Each successful call is billed at the price shown by `inspect_capability`; failed calls are free. Quote first when you plan more than ~20 calls, and keep within the budget the user agreed.
