Fello enforces a per-client rate limit on incoming API requests to maintain a stable and reliable service. Exceeding these limits will result in a 429 Too Many Requests response, at which point clients should implement back-off strategies or queue future requests.
Fello enforces rate limits at both the Custom App (or API Key) level and at the Account level. Each rate limit implementation returns a set of response headers that provide insights into the current rate limit status.
Note: These default rate limits may be increased upon consultation with the Fello team and subsequent approval for elevated limits.
We use sliding window strategy for our 10-second window rate limiter.
An account is permitted up to 350,000 requests per day.
When the rate limit is exceeded, Fello returns a 429 Too Many Requests
response. In such cases, consider the following strategies:

responses continue.
