Vichar Docs

Migrate from OpenRouter

Swap base URL, key, and model IDs to move to Vichar.

Change three things:

  1. Base URL: https://openrouter.ai/api/v1 becomes https://api.vichar.io/v1.
  2. API key: replace your OpenRouter key with a vichar_* key.
  3. Model IDs: OpenRouter provider/model IDs map to vichar-* IDs. Find the equivalent on vichar.io/models (for example vichar-sonnet-5.5).

Everything else (chat completions shape, streaming, tools, response_format) works the same. Vichar does not expose :free variants; experimental catalogue entries are marked free in GET /v1/models.
