# Vercel AI Gateway The [Vercel AI Gateway](https://vercel.com/ai-gateway) provides a unified API to access hundreds of models through a single endpoint. * Provider: `vercel-ai-gateway` * Auth: `AI_GATEWAY_API_KEY` * API: Anthropic Messages compatible ## Quick start 1. Set the API key (recommended: store it for the Gateway): ```bash openclaw onboard --auth-choice ai-gateway-api-key ``` 2. Set a default model: ```json5 { agents: { defaults: { model: { primary: "vercel-ai-gateway/anthropic/claude-opus-4.5" }, }, }, } ``` ## Non-interactive example ```bash openclaw onboard --non-interactive \ --mode local \ --auth-choice ai-gateway-api-key \ --ai-gateway-api-key "$AI_GATEWAY_API_KEY" ``` ## Environment note If the Gateway runs as a daemon (launchd/systemd), make sure `AI_GATEWAY_API_KEY` is available to that process (for example, in `~/.openclaw/.env` or via `env.shellEnv`).
