9Router — Web Search
Requires NINEROUTER_URL (and NINEROUTER_KEY if auth enabled). See https://raw.githubusercontent.com/decolua/9router/refs/heads/master/skills/9router/SKILL.md for setup.
Discover
curl $NINEROUTER_URL/v1/models/web | jq '.data[] | select(.kind=="webSearch") | .id'
curl "$NINEROUTER_URL/v1/models/info?id=tavily/search"
IDs end in /search (e.g. tavily/search). Combos (owned_by:"combo") chain providers with auto-fallback.
