## Tools (3)

- `get_domain`: Look up one domain on 199.domains: whether it is for sale, sold or not listed, its fixed price, total with fee, buy URL, a short summary, the buying terms, and similar names for sale.
- `list_collections`: List the curated collections on 199.domains (by extension, price band, naming style and industry, e.g. AI agent, fintech, health, developer tools) with live listing counts. Use a slug as the collection filter in search_domains.
- `search_domains`: Search the live 199.domains inventory of brandable and keyword domain names for sale at fixed prices ($29 to $199). Pass what the person is building (e.g. 'ai sales agent', 'fitness app', 'stock trading', 'developer tool') and optional filters. Returns real listings only, each with its price, total with fee and buy URL. It never suggests names to register elsewhere.
