API Rate Limit Header Parser
Paste X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers to get a compact local summary. Header names are case-insensitive and no request is made.
A QUICK WALKTHROUGH
How to use this tool
- Paste one header per line as Name: value.
- Parse the three supported rate limit headers.
- Review limit, remaining, simple usage progress, and reset epoch time in UTC.
Three explicit headers
Only X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset are read. Header matching ignores case; other headers are ignored rather than guessed.
Simple progress estimate
Used progress is calculated as (limit − remaining) ÷ limit and clamped to 0–100%. It is a display aid, not a provider-specific billing or quota interpretation.
No network request
Parsing happens entirely in your browser. The page does not call an API, validate a provider’s policy, or infer reset behavior beyond converting a Unix epoch in seconds to UTC.
GOOD TO KNOW
Common questions
Which headers are supported?
Only X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset. Header names are matched without case sensitivity.
What does reset mean?
The reset value is interpreted as a Unix epoch timestamp in seconds and displayed as UTC. Providers may document different semantics, so confirm their API documentation.
Does this contact my API?
No. You paste text into the page; no network request is made.
