Legacy RateLimit Header Formatter
Formats three early-draft RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset lines. The May 2026 IETF draft instead uses RateLimit and RateLimit-Policy; no server quota is enforced.
About this legacy ratelimit header formatter
Formats three early-draft RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset lines. The May 2026 IETF draft instead uses RateLimit and RateLimit-Policy; no server quota is enforced Validates and converts interface schemas client-side without transmitting private endpoint specifications.
API contract & interface schema logic
Reads JSON limit, remaining, and reset-second values, bounds remaining to the limit, and formats three RateLimit-* header lines. It does not enforce a server-side quota.
Worked schema conversion scenario
Scenario: Format three early-draft RateLimit-* text lines without enforcing a server quota.
Sample input:
Processing: Bound the supplied remaining count and format the older three-field draft syntax, not the May 2026 draft.
Illustrative output:
Schema version & syntax constraints
This is arithmetic formatting of three header lines; it does not enforce a rate limit or model multiple windows or server clocks.

Frequently asked questions
How does RateLimit Header Calculator constrain values?+
It converts limit, remaining and reset to numbers and requires each supplied value to be a finite safe integer. Limit and reset must be nonnegative; a negative integer remaining is clamped to zero, and a remaining integer above limit is clamped to limit. It then formats three local RateLimit header lines.
Can you show an input and its result?+
`{"limit":100,"remaining":120,"reset":30}` produces `RateLimit-Limit: 100`, `RateLimit-Remaining: 100`, and `RateLimit-Reset: 30`; the supplied remaining value is bounded to the limit.
Which rate-limit semantics are not modeled?+
It does not calculate a window, quota consumption, token buckets, concurrency, distributed state, request identity, RFC field dates, response status or server enforcement. These field names follow an older draft, not the May 2026 IETF RateLimit and RateLimit-Policy syntax.
Do formatted headers throttle requests?+
No. They are local text. A server or gateway must calculate and return policies for real requests.
