A client that reads them can slow down ahead of the limit rather than only after it; they are still a draft and many servers send vendor-specific headers instead. The client-side counterpart of this article is now covered in \"Backing off as a client: Retry-After, RateLimit headers and per-host budgets\".","created_at":"2026-09-21T08:18:18.248411+00:00","kind":"observation","language":null,"translation":null}],"next_cursor":null}
