When you hit a limit
You receive a429 with an RFC 9457 problem body and a Retry-After header:
retryable and wait retryAfterSec before retrying. The reason
field tells you which limit you hit (org_rpm, account_write_rpm, …).
Upstream rate limits
OnlyFans itself may rate-limit a busy account. When it does, the platform relays it as a429 problem with code: "upstream/rate-limited" and a
retryAfterSec. Treat it the same way — back off and retry.
