Rate Limits

MetaLink enforces two types of rate limits: per-minute and monthly.

Limits by Plan

Monthly limits are per user, not per key. If you have multiple API keys, they share the same monthly quota.

Every successful response includes these headers:

Header	Description
`X-RateLimit-Limit`	Max requests per minute for your tier
`X-RateLimit-Remaining`	Requests remaining in the current minute
`X-RateLimit-Reset`	Unix timestamp when the minute window resets
`X-Monthly-Limit`	Max requests per month for your tier
`X-Monthly-Used`	Requests used this month
`X-Monthly-Remaining`	Requests remaining this month

If you exceed either limit, you’ll receive a 429 Too Many Requests response. Per-minute limit exceeded:

Monthly limit exceeded:

Response includes X-Monthly-Reset header (ISO 8601 date-time, e.g., 2026-04-01T00:00:00Z)
Monthly counters reset on the 1st of each month at midnight UTC
