Vercel AI Gateway

Section titled “Vercel AI Gateway”

The Vercel 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

Section titled “Quick start”
  1. Set the API key (recommended: store it for the Gateway):
Terminal window
openclaw onboard --auth-choice ai-gateway-api-key
  1. Set a default model:
{
  agents: {
    defaults: {
      model: { primary: "vercel-ai-gateway/anthropic/claude-opus-4.5" },
    },
  },
}

Non-interactive example

Section titled “Non-interactive example”
Terminal window
openclaw onboard --non-interactive \
  --mode local \
  --auth-choice ai-gateway-api-key \
  --ai-gateway-api-key "$AI_GATEWAY_API_KEY"

Environment note

Section titled “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).
