Unverified50% confidenceFactExact time
The 503 UNAVAILABLE returned by the Gemini API indicates server-side overload and is unrelated to the user's quota; there is no retry delay in the error, so exponential backoff with jitter should be used to retry.

UnverifiedThe Gemini API returns 429 RESOURCE_EXHAUSTED, indicating the violated window in details[].quotaId and giving a retryDelay for per-minute limits, with its daily quota resetting at midnight Pacific Time.74% similarUnverifiedThe Gemini API free tier has a quota of 0 for Pro-series models such as gemini-3.1-pro-preview, returning limit: 0, and it remains 0 after the daily reset, so waiting to retry is pointless.72% similarUnverifiedWhen Gemini's quota is exhausted it throws a gRPC-style RESOURCE_EXHAUSTED error wrapped in an HTTP 429 response, rather than returning a custom header suite.72% similarUnverifiedA Gemini API 429 error only tells the caller that resources are insufficient, but does not say which type of resource is lacking; the correct way to handle a 429 is to parse the details array to distinguish complete lack of quota, per-minute overage and daily overage.72% similarUnverifiedGemini membership subscriptions can be cancelled at any time.69% similar
