tavily/<model-id>How Tavily billing works with kRouter
Tavily is pay-per-token. You bring your own API key and kRouter routes to it, so you keep your own rate limits and billing relationship. kRouter authenticates it via apikey.
Through kRouter, Tavily serves web search, exposed on /v1/search so an agent can look things up mid-conversation and URL fetching, so an agent can read a page mid-conversation. Requests reach it through the same local OpenAI-compatible endpoint as every other provider, so switching to or from Tavily is a one-line model change in your client rather than a rewrite.

Tavily FAQ
Is Tavily free through kRouter?
Tavily is pay-per-token: you bring your own API key and are billed by Tavily at their rates. kRouter adds nothing on top and is free and MIT-licensed.
How do I use Tavily with Claude Code or Cursor?
Connect Tavily in the kRouter dashboard, then point your tool at kRouter's local endpoint (http://localhost:20128/v1) with a kRouter API key. Any OpenAI-compatible client works, and models are addressed as tavily/<model>.
What happens when Tavily is rate limited?
kRouter detects the limit, parks that account until its real reset time, and fails over to your next connected account or provider — so the request still completes instead of erroring.
