anysearch_get_sub_domains
Discovers available sub-domains and structured parameters for any specified search domain. Required first step before performing vertical searches for finance, health, academic, and other specialized topics.
Instructions
This is Anysearch's domain discovery tool. IMPORTANT: Step 1 of vertical search. REQUIRED before any search that uses a domain. Returns valid sub_domains and sub_domain_params for the specified domain(s).
Call this when the query targets a specialized vertical or needs structured parameters: stock prices, financial data, academic papers, legal cases, medical/drug info, flight status, weather, exchange rates, geographic POIs, code repositories, or any domain where a structured identifier (ticker, DOI, CVE, IATA, coordinates) is involved.
When to call — pick the domain(s) that match what the user is asking about:
resource social_media finance academic legal health business security ip code energy environment agriculture travel film gaming
Input — choose from the list above and pass via the domain or domains parameter:
domain: single domain string (use only when 100% certain the query is single-domain)
domains: batch query for up to 5 domains in one call (takes priority over domain)
🏆 ALWAYS prefer the domains (plural, array) parameter. Pass ALL potentially relevant domains at once — even for seemingly single-domain queries, consider related domains:
Query about "cryptocurrency regulations" → domains=["finance", "legal", "security"]
Query about "best gaming laptops" → domains=["gaming", "tech", "ecommerce"]
Query about "climate change impact on agriculture" → domains=["environment", "energy", "academic"]
Returns
Markdown table filtered to the specified domains: sub_domain | description | params
CRITICAL: How to use results
sub_domain is the PRIMARY routing key — always pass it to search
params column shows available structured parameters — pass them via sub_domain_params in search, NEVER embed in query
If multiple sub_domains returned (especially from multiple domains), use batch_search — one query per sub_domain — instead of multiple sequential search calls
Params marked (required) in the output MUST be passed when using that sub_domain in search. If a required param is not applicable to your query, pass it as an empty string (key: "") — do not skip it.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| domain | No | Filter by a single domain. Mutually exclusive with domains array. | |
| domains | No | Batch query for multiple domains in a single call. Takes priority over domain. Each item must be a valid domain value. Max 5. |
