Inference rate limits apply only to BYOK (Bring Your Own Key) requests and scale with your usage tier. Platform keys have no inference rate limits. Management endpoints have separate per-user limits.

​
Prerequisites

​
Inference rate limits

Your rate limit tier is determined by rolling 30-day inference spend and recalculates every 60 minutes:
Tier30-day spendBYOK RPMBYOK monthly capPlatform fee
Starter0–0 – 500301,0002.0%
Growth500–500 – 10,00012050,0001.0%
Scale$10,000+600Unlimited0.5%
EnterpriseCustom1,200UnlimitedCustom
Enterprise tier is assigned manually — it is not auto-detected from spend.
The limits above apply only to BYOK requests. See BYOK for details.

​
Rate limit headers

Every response carries OpenAI-compatible rate limit headers:
HeaderDescription
Retry-AfterSeconds until rate limit resets (RFC 7231)
X-RateLimit-Limit-RequestsRequests allowed per window
X-RateLimit-Remaining-RequestsRequests remaining in current window
X-RateLimit-Reset-RequestsISO 8601 timestamp when the window resets

​
Management API rate limits

Management endpoints have separate per-user rate limits:
EndpointLimit
API key creation10/min
Billing checkout5/min
Billing portal5/min
Team invites20/min
BYOK operations20/min
Workspace creation5/min
Account deletion2/min
Budget writes10/min
Management reads (API key)60/min (per IP)
Public registry60/min (per IP)

​
Handle 429 responses

When you exceed a rate limit, the API returns a 429 Too Many Requests response with a Retry-After header indicating when to retry. 
{
  "error": {
    "message": "Rate limit exceeded. Retry after 12 seconds.",
    "type": "rate_limit_error",
    "code": "rate_limit_exceeded"
  }
}
The Auriko SDK handles retries automatically with exponential backoff (up to 2 retries by default). For manual handling, see Error handling — Retry manually.
