The Zero-Downtime Agent: Managing API Rate Limits

Reliability · updated Sun Feb 22

Five strategies to prevent 429 errors and keep autonomous agents within rate limits.

Steps

  1. Apply jittered exponential backoff for rate-limit errors.
  2. Route non-critical tasks to a fallback model when the primary model hits limits.
  3. Enforce per-session token-per-minute budgets.
  4. Batch requests when possible to reduce concurrency pressure.
  5. Cache identical tool responses for short TTLs to reduce repeated calls.
