Every Zerion API key has its own rate limits. Development keys are free to use.
For development keys, the limit is currently set at 5k requests per day. This is spread across ~60 requests per minute with a 30 seconds waiting period. The dev key limits are meant to remain appropriate for local development.
If you reach the limit, the Zerion API will return a 429 status code with an error for every request beyond the limit before it will be reset.
If you need a key for a production environment up to 200+ RPS, please contact us at [email protected] with your dev key details and any special requirements. We'll send over a custom pricing proposal with best in-class usage pricing!
