One of the first steps to ensure a smooth transition is to use standard headers for your rate limit information. The most common headers are X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset, which indicate the maximum number of requests, the remaining number of requests, and the time when the limit will be reset, respectively. These headers are widely recognized and supported by many libraries and tools, and they can help you avoid naming conflicts or ambiguities with other headers. If you use these headers, you can also leverage existing documentation and examples to explain your rate limit policy to your clients.
