# How to Source Rare Items with OpenClaw

Find hard-to-find products by checking which marketplaces serve your region and searching all available sources. OpenClaw is ideal when you want to run the same rare-item search across multiple regions or product variants in a repeatable batch.

## Setup

openclaw mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter in OpenClaw: openclaw mcp add toolrouter -- npx -y toolrouter-mcp
2. Define the item variants, target regions, and output schema before the first batch.
3. Run `source_coverage` and `search_listings` with `marketplace-search` for each region and variant combination.
4. Review results, discard noise, and rerun only promising region-variant pairs on the next pass.

## Example Prompt

```
Use marketplace-search to search for a Technics SL-1200 MK2 turntable across Europe. Check source coverage per country, search all sources, and return results in a stable schema so I can rerun this search weekly to catch new listings.
```

## Tips

- Batch multiple item variants into one session to maximize coverage per run.
- Lock the output schema early so you can diff results across weekly runs.
