API response and error decoder
Paste an HTTP response, error body, headers, or provider message. Separate transport, authentication, throttling, validation, and upstream failures before changing code.
- Input
- HTTP transcript, JSON error, headers, or plain text
- Output
- Layered verdict, evidence, redaction warnings, and next checks
Evidence
HTTP 429: A rate, quota, concurrency, or resource lock limit blocked the request.
Retry-After is present; it should take precedence over a guessed delay.
The reported request window has no remaining capacity.
Next checks
01Parse Retry-After as either delta-seconds or an HTTP date before scheduling the next attempt.
OPERATING NOTES01–03
What this tool checks—and what it does not.
- Local analysis
The supplied value is processed in the active tab. Remote endpoint behavior is not inferred when the evidence does not contain it.
- Evidence before advice
The report separates observed fields from implementation guidance. Preserve request IDs and provider error codes for production incidents.
- Version-aware verification
Provider behavior changes. Each related field note links to the official source used for the current rule.
THE RULES BEHIND THIS TOOL03 NOTES
Why it decided that.
Each note states the rule this workbench applies and cites the provider or standards document it came from.
Distinguish API rate limits, quota exhaustion, concurrency limits, and resource locks from a 429 response and its headers.
Read the note →Authentication field noteAPI 401 vs 403: credential failure or permission failure?Use the status, WWW-Authenticate challenge, token state, and resource policy to separate API 401 Unauthorized from 403 Forbidden.
Read the note →HTTP header referenceRetry-After header: seconds vs HTTP dateParse Retry-After safely when an API returns delta-seconds or an HTTP-date, then combine it with bounded backoff and clock-skew handling.

About this workbench
Does the incident decoder upload my data?
No. The value you supply is parsed and evaluated in the active browser tab. No account is required and no remote endpoint is called on your behalf.
What does this tool read, and what does it return?
It reads http transcript, json error, headers, or plain text, and returns layered verdict, evidence, redaction warnings, and next checks.
How current are the rules it applies?
Each rule links to the field note that cites its primary provider or standards source, with the review date shown on that note. Provider behaviour changes, so verify against your pinned version before deploying.
