Running into error codes while using OPenClaw can be frustrating. Whether it’s an API call failure or a connection timeout, quickly identifying the issue gets your workflow back on track. This guide breaks down the most common OPenClaw errors and manual fix steps to help you save time.
Invalid or Expired API Key
Error code 401 usually means your API key is incorrect or has expired. Log into your OPenClaw dashboard and go to the “API Keys” page to check the current status. If you see a red “Expired” label, generate a new key and replace the old one in your code. Make sure there are no extra spaces when copying — many beginners trip up on this small detail.
If the key is valid but you still get a 403 error, the issue might be missing permission scopes. Double-check that your key has the required model access, such as “claw-4” or “claw-vision”. After saving, wait about a minute before retrying — OPenClaw’s permission sync can sometimes lag.
Rate Limiting (429 Error)
Too many requests in a short time trigger a Rate Limit, shown by error code 429. OPenClaw’s free plan allows up to 30 requests per minute, while paid plans range from 60 to 200 depending on your tier. The simplest fix is to add delays in your code. For example, in Python, use time.sleep(2) to ensure at least 2 seconds between requests. For batch processing, consider using an exponential backoff algorithm.
Also check if you’re running multiple scripts simultaneously. The “Usage” page on your dashboard shows real-time request rates. If you see it going over the red line, stop and wait a few minutes. Let it cool down before trying again — don’t brute force it.
