+# 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
+moltbot 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
+moltbot 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 `~/.clawdbot/.env` or via
+`env.shellEnv`).
