Spline · Rate Limits

Spline Rate Limits

Spline does not publish a public REST API for 3D generation, so per-RPS rate limits do not apply. SDK code APIs and webhooks are governed by the user's plan-based AI credit allowances and project export limits.

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

It captures 2 rate-limit definitions, measuring ai_credits and scenes.

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 3D, Design, AI, Collaboration, and Web.
