Castr · Rate Limits

Castr Live Rate Limits

Castr does not publish fixed numeric request-rate limits for its REST API in the developer documentation. In practice the operative limits on a Castr account are the plan allowances - number of concurrent streams, number of multistream destinations, upfront (ingest) bandwidth, player (delivery) bandwidth, and video storage - rather than a per-minute API call cap. Sustained streaming and delivery are governed by those plan allowances; exceeding them requires upgrading the plan.

Castr Live Rate Limits is the machine-readable rate-limit profile for Castr on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests, streams, destinations, and bytes.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Live Streaming, Video Hosting, Rate Limiting, and Quotas.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
Plan-Bound Quotas
The effective ceilings are plan concurrency, bandwidth, and storage allowances rather than an API request-rate cap; upgrade the plan to raise them.
