ExtremeRouter — Web Search
Requires NINEROUTER_URL (and NINEROUTER_KEY if auth enabled). See https://raw.githubusercontent.com/rsalmn/extremerouter/refs/heads/master/skills/extremerouter/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.

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