Marginalia Search Rate Limits

Machine-readable rate limit definitions for the Marginalia Search API surface. Captures per-tier quotas, burst behavior, response signaling, and recovery semantics. Defaults are scaffold values to be replaced with published provider limits.

Marginalia Search Rate Limits is the machine-readable rate-limit profile for Marginalia Search on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, across the free, professional, and enterprise tiers, measuring requests_per_minute and requests_per_month.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Open Source, Search, Web Search, Rate Limiting, and Quotas.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter, honoring the Retry-After header when present.
Burst Handling
Short bursts above the steady-state limit are tolerated up to the documented burst ceiling before throttling engages.
Quota Reset
Monthly quotas reset at the start of each calendar month in UTC. Per-minute and per-second windows reset on a sliding-window basis.
Fair Use
Even on uncapped enterprise tiers, sustained usage that materially impacts shared infrastructure may be subject to fair-use throttling.
