Docs/Rate limits
Rate limits
Two limits apply to every key: a per-minute request rate that scales with your plan, and your plan's monthly credit quota. The per-minute window is 60 seconds, tracked per endpoint. Hitting either limit returns 429.

Response headers
Authorization: Bearer mm_live_…Response headers
X-RateLimit-Limit/X-RateLimit-Remaining- your per-minute allowance and what's left of it in the current window.X-RateLimit-Reset- seconds until the window resets.X-Quota-Limit/X-Quota-Remaining- your monthly credit cap and remainder. Omitted on unlimited plans.X-Cache-HITwhen the response came from the 24-hour cache.
Repeating an identical request within 24 hours is served from cache - it costs 0 credits but still counts toward the per-minute rate. There is no Retry-After header - on 429 the statusMessage tells you the seconds until reset (Rate limit exceeded. Retry in 42s.).
