API Rate Limit Header Parser
Decode rate-limit headers into a plain-English countdown
Paste raw response headers from any API and this tool recognizes the common rate-limit conventions in the wild — GitHub-style X-RateLimit-*, the IETF draft standard RateLimit-*, and RFC 7231 Retry-After. It automatically figures out whether a Reset value is a Unix epoch timestamp or a relative seconds-from-now count based on its magnitude, then shows both the raw value and a human countdown like "resets in 12m 4s".
- →Parses X-RateLimit-Limit/Remaining/Reset (GitHub-style)
- →Parses RateLimit-Limit/Remaining/Reset (IETF draft standard)
- →Handles Retry-After in both integer-seconds and HTTP-date format
- →Auto-detects epoch-seconds vs relative-seconds Reset values by magnitude
- →Watermarked by Cikal Studio Labs · Works on any device, no install required
