Rate limits - Arbytra

Rate limits scale with your plan. See Plans and billing for tier thresholds, requests-per-minute (RPM) limits, and monthly caps.

Prerequisites

An Arbytra API key

Check rate limit headers

Chat completion responses include request-level rate limit headers:

Header	Description
`Retry-After`	Seconds until rate limit resets; present on 429 responses only (RFC 7231)
`X-RateLimit-Limit-Requests`	Requests allowed per window
`X-RateLimit-Remaining-Requests`	Requests remaining in current window
`X-RateLimit-Reset-Requests`	ISO 8601 timestamp when the window resets

Handle 429 responses

When you exceed a rate limit, the API returns a 429 Too Many Requests response with a Retry-After header:

{
  "error": {
    "message": "Rate limit exceeded. Retry after 12 seconds.",
    "type": "rate_limit_error",
    "param": null,
    "code": "rate_limit_exceeded",
    "doc_url": "https://arbytra.com/errors/rate_limit_exceeded"
  }
}

The Arbytra SDK (Python, TypeScript) retries failed requests with exponential backoff (up to 2 retries by default). For manual handling, see Error handling — Retry manually.
