Please review the MedDRA API documentation on throttling limits." The numbers, windows and scope of those limits are in the programmer guides behind the subscriber login at https://www.meddra.org/private/api-info and are not published, so no limit is recorded here. No RateLimit-* / X-RateLimit-* / Retry-After header is declared in the contract or returned on the anonymous probes we could make.
