Limit Ladder - check your API rate-limit policy before callers trip it

Check a public API's rate-limit policy so integrators can predict, observe and adapt to throttling, then write the published policy and the override and change rollout. Free in your browser: every published rate normalised, burst equal to sustained caught, refill time and the per-region multiplier worked out, documented limits diffed against enforced ones, one pasted throttle response read (429 or a throttle inside 200, the Retry-After form, legacy and IETF headers, reset semantics, caching), fairness, overrides and change notice checked, the algorithm and header family ranked, plus the published limits table and an example 429. A metered run writes the published policy, or the rollout. Built on the SkillSafe skill @samber/api-rate-limit-policy, from samber/developer-platform-skills (MIT), by Samuel Berthe.
