Many AI applications begin with one provider and then need more flexibility: fallback models, model experiments, or different models for different product workflows.

RouterBase gives developers an OpenAI-compatible API shape at https://routerbase.com/v1, so the first experiment can stay small: change the base URL, set a RouterBase API key, and choose a model id.

Minimal curl request

curl https://routerbase.com/v1/chat/completions \

-H "Authorization: Bearer $ROUTERBASE_API_KEY" \
