9router-web-search	Web search via 9Router /v1/search using Tavily / Exa / Brave / Serper / SearXNG / Google PSE / Linkup / SearchAPI / You.com / Perplexity. Use when the user wants to search the web, look up information, find articles, or query a search engine.

9Router — Web Search

Requires NINEROUTER_URL (and NINEROUTER_KEY if auth enabled). See https://raw.githubusercontent.com/decolua/9router/main/app/skills/9router/SKILL.md for setup.

Discover providers

curl $NINEROUTER_URL/v1/models/web | jq '.data[] | select(.kind=="webSearch") | .id'

IDs end in /search (e.g. tavily/search). Combos (owned_by:"combo") chain providers with auto-fallback.

Endpoint

POST $NINEROUTER_URL/v1/search

Field	Required	Notes
model (or provider)	yes	from /v1/models/web (e.g. tavily/search or just tavily)
query	yes	search query
max_results	no	default 5
search_type	no	web (default) / news
country, language, time_range, domain_filter	no	provider-dependent

Examples

curl -X POST $NINEROUTER_URL/v1/search \
  -H "Authorization: Bearer $NINEROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"tavily/search","query":"9Router open source","max_results":5}'

JS:

const r = await fetch(`${process.env.NINEROUTER_URL}/v1/search`, {
  method: "POST",
  headers: { "Authorization": `Bearer ${process.env.NINEROUTER_KEY}`, "Content-Type": "application/json" },
  body: JSON.stringify({ model: "search-combo", query: "latest LLM benchmarks", max_results: 10 }),
});
console.log(await r.json());
