Rate limits

BlobRouter v0.1 · Last updated: August 2026 · Architecture version: 2.0

Limits are enforced per customer (key rate:{customerId}) after authentication.

Limits (requests / minute)

One SDK upload uses multiple control-plane requests (init + complete), so limits are sized for that.

HTTP 429 with:

{
  "error": "Rate limit exceeded",
  "code": "rate_limit_exceeded",
  "retryAfter": 60,
  "limit": 300
}

Header:

Retry-After: 60

SDKs treat 429 as retryable (exponential backoff). See Retries.
