What is API Rate Limiting?
Rate limiting controls how many API requests you can make. Learn about rate limits on OpenClaw and strategies for managing them.
Definition
API Rate Limiting
API rate limiting is a mechanism that restricts the number of API requests a client can make within a specified time period. AI API providers impose rate limits to ensure fair usage, prevent abuse, and maintain service stability across all users.
Why It Matters
Why You Should Care
Hitting rate limits means your application's AI features stop working until the limit resets. This can cause errors, degraded user experience, and lost revenue. For OpenClaw users, prompt compression indirectly helps with rate limits by reducing token throughput per request — making it easier to stay within tokens-per-minute limits.
How It Works
Under the Hood
Rate limits are typically expressed as requests per minute (RPM) and tokens per minute (TPM). When you exceed either limit, the API returns a 429 (Too Many Requests) error. Strategies for managing rate limits include request queuing, exponential backoff, and reducing token counts per request. claw.zip helps with the token-per-minute limit by compressing prompts before they reach the OpenClaw API.
