All use cases

Built-in presets

Start on anyrouter/free or anyrouter/auto

Two built-in virtual models: free failover on every plan (anyrouter/free) and stable paid failover (anyrouter/auto). Do not pick a flaky SKU for your first request.

What this is for

A first request that pins a single free SKU often 404s or 429s. You want something that is answering right now, with automatic fallback.

Steps, then copy

  1. 1.Create a key. anyrouter/free needs the Go plan ($2/mo) or a donated provider key; it does not deduct credits and has no daily limit.
  2. 2.Call model anyrouter/free for the subsidized free chain, or anyrouter/auto for paid models that are healthy right now.
  3. 3.Read the model pages and the free-tier docs for failover behavior.
