Rate limit
A rate limit caps throughput. It is separate from credits: credits limit how much you may spend, rate limits how fast you may spend it.

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 41
X-RateLimit-Reset: 1754827200| Plan | Requests/minute | Concurrent async jobs |
|---|---|---|
| Developer | 60 | 2 |
| Scale | 300 | 10 |
| Enterprise | custom | custom |
| Test keys | 20 | 2 |
Limits are per key; credits pool per organization. A token bucket allows a 2× burst for up to 10 seconds. Uploads are separately capped at 20 files per minute.
Exceeding a limit returns 429 rate_limit_error with Retry-After in seconds.
Concurrency, not just rate
Async jobs count against a separate concurrency budget for as long as they run. Two in-flight
deep_review searches on Developer will block a third until one finishes — that is a 429, not a
queue.
