Rate Limits

Understanding API rate limits and how to handle them.

Overview

RelayAPI applies rate limits per API key to ensure fair usage and platform stability.

Default Limits

Handling Rate Limits

When you hit a rate limit, you'll receive a 429 response:

{
  "error": {
    "code": "RATE_LIMITED",
    "message": "Rate limit exceeded. Please try again shortly."
  }
}

Back off and retry with exponential delay (e.g. 1s, 2s, 4s, capped at your plan's per-minute budget). Rate limit counters reset on a per-minute sliding window.

Platform Rate Limits

In addition to API rate limits, each social platform has its own rate limits. RelayAPI respects these automatically and queues posts when platform limits are reached. See individual platform pages for platform-specific rate limits.
