In depth
A single HTTP endpoint from Vercel that fronts hundreds of models from many providers behind one API key. You reference a model by a plain string like anthropic/claude-opus-4.8 or moonshotai/kimi-k2.5 and the request routes to the right provider, with automatic retries, embeddings, and spend monitoring across providers in one place. It is the default provider in the Vercel AI SDK when you pass a model as a string, and per its docs it adds no token markup, including with Bring Your Own Key.
