Why am I seeing HTTP 429 ratelimiterror from Anthropic

That means your Anthropic quota/rate limit is exhausted for the current window. If you use a Claude subscription (setup‑token or Claude Code OAuth), wait for the window to reset or upgrade your plan. If you use an Anthropic API key, check the Anthropic Console for usage/billing and raise limits as needed.
Tip: set a fallback model so OpenClaw can keep replying while a provider is rate‑limited. See Models and OAuth.
