Step-by-step guide to migrating OpenClaw to API keys or alternative providers. If OpenClaw is throwing `403 permission_error` when it tries to call Claude, your OAuth session has been revoked by Anthropic. This is not a bug you can wait out — it's a deliberate policy change. Here's exactly what to do. **Time estimate:** 10–20 minutes **Difficulty:** Easy **Who this affects:** OpenClaw users who signed in with Claude Pro or Max subscription credentials (OAuth flow) rather than a direct API key --- ## First: Confirm You're Affected Check your OpenClaw logs. If you see something like: ``` Error: 403 permission_error — OAuth token rejected Model: claude-3-5-sonnet-20241022 Auth method: oauth ``` You're in the right place. If you're using an API key from console.anthropic.com and seeing 403s, that's likely today's separate outage — wait it out. --- ## Option A: Switch to a Direct Anthropic API Key This keeps Claude as your model while removing the OAuth dependency. ### Step 1: Get an API Key 1. Go to [console.anthropic.com](https://console.anthropic.com) 2. Sign in with your Anthropic account 3. Navigate to **API Keys** → **Create Key** 4. Copy the key (starts with `sk-ant-`) Note: This is **separate billing** from your Pro/Max subscription. You'll be charged per token, not a flat monthly fee. For light personal use, costs are typically $1–5/month. For heavy agentic workloads, budget accordingly. ### Step 2: Update OpenClaw Config In your `config.yml` (or through OpenClaw's settings UI): ```yaml providers: anthropic: auth_method: api_key api_key: sk-ant-your-key-here model: claude-3-5-sonnet-20241022 ``` Or via the CLI: ```bash openclaw config set anthropic.auth_method api_key openclaw config set anthropic.api_key sk-ant-your-key-here ``` ### Step 3: Restart and Test ```bash openclaw restart openclaw test-provider anthropic ``` You should see `✓ Provider connected` in the output. --- ## Option B: Migrate to an Alternative Provider If you don't want to pay per-token to Anthropic, several solid alternatives work with OpenClaw's OpenAI-compatible provider interface. ### Kimi K2.5 (Recommended Alternative) Kimi K2.5 (by Moonshot AI) has been getting strong reviews as a Claude Sonnet-class model with a generous free tier and affordable paid API. It's what multiple community members have migrated to. **Setup:** 1. Create an account at [platform.moonshot.cn](https://platform.moonshot.cn) (English UI available) 2. Generate an API key 3. Update OpenClaw: ```yaml providers: default: provider: openai_compatible api_base: https://api.moonshot.cn/v1 api_key: sk-your-kimi-key model: moonshot-v1-128k ``` ### MiniMax MiniMax offers a capable model with OpenAI-compatible endpoints: ```yaml providers: default: provider: openai_compatible api_base: https://api.minimax.chat/v1 api_key: your-minimax-key model: abab6.5s-chat ``` ### Ollama (Local, Free) For a zero-cost fallback that works offline: ```bash ollama pull llama3.2 ``` ```yaml providers: default: provider: openai_compatible api_base: http://localhost:11434/v1 api_key: ollama model: llama3.2 ``` Performance will depend on your hardware. On Apple Silicon, `llama3.2:8b` runs well in real-time. --- ## Option C: Keep OAuth as Fallback, Add API Key as Primary If you're not ready to abandon OAuth entirely (maybe hoping Anthropic reverses the policy), configure a provider priority so OpenClaw falls back gracefully: ```yaml providers: primary: provider: openai_compatible api_base: https://api.moonshot.cn/v1 api_key: sk-your-kimi-key model: moonshot-v1-128k fallback: provider: anthropic auth_method: api_key api_key: sk-ant-your-key-here model: claude-3-5-sonnet-20241022 ``` This way your agents keep running on Kimi K2.5 while you maintain access to Claude via API key for tasks where you specifically want it. --- ## Understanding the Cost Difference Here's a rough breakdown for common agentic workloads: | Provider | Pricing Model | Est. Monthly Cost (moderate use) | |----------|--------------|----------------------------------| | Claude Pro (OAuth) | $20/month flat | $20 (now blocked for OpenClaw) | | Claude API (direct) | Per token (~$3/M input, $15/M output) | $2–15 depending on usage | | Kimi K2.5 | Per token (competitive rates) | $1–8 | | Ollama (local) | Free | $0 (electricity only) | For most personal agent use cases, direct Claude API or Kimi K2.5 will come out cheaper than a flat Pro subscription — especially if your agents run on a schedule rather than constantly. --- ## Community Resources - **OpenClaw GitHub Issue #31306** — Active thread with community-submitted config snippets for alternative providers - **OpenClaw Discord #providers** — Real-time discussion of working configurations - **Medium (rentierdigital)** — Full documented migration story from Claude OAuth to Kimi K2.5 on a $15/month VPS --- ## Sources 1.
