Lunary · Rate Limits

Lunary Rate Limits

Lunary's API uses a sliding-window rate limiter. The current published limit is 30 requests per second per API key. Standard HTTP codes are returned (429 rate-limit, 422 invalid params, 403 unauthorized, 50x server). Self-hosted deployments are unconstrained beyond your own infrastructure.

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

It captures 1 rate-limit definition, measuring requests-per-second.

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 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include AI Evaluation, Observability, Open Source, LLM, and Tracing.

Policies

Backoff Strategy
On 429, apply exponential backoff with jitter.
Self-Host Option
For very high event volume, deploy self-hosted to remove rate-limit ceiling.
