Transistor Rate Limits

Transistor publishes a single, explicit API rate limit: 10 requests per 10 seconds. Exceeding the limit returns an HTTP 429 error and blocks API access for 10 seconds. Transistor also advises against using the API as a primary live data source for website content, recommending caching of API responses instead. Separate from API request limits, each subscription plan caps monthly podcast downloads and the number of private podcast subscribers.

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

It captures 3 rate-limit definitions, measuring requests, downloads, and subscribers.

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

Tagged areas include Podcasting, Podcast Hosting, API, Rate Limiting, and Quotas.

Policies

Throttle Window
Requests are counted in a rolling 10-second window; more than 10 in that window trips the limit.
Cooldown
After a 429, API access is blocked for 10 seconds before requests are accepted again.
Caching Guidance
Transistor recommends caching API responses and not using the API as a live data source for website content.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor the cooldown after a 429 response.
