Rate Limits

The Leadfeeder API enforces rate limits to ensure fair usage and system stability. Limits are applied per API key.

Request limit: 10 requests per second

Burst: Up to 15 requests can be made in a single burst before throttling is applied

Monthly quota: 100,000 requests per month

When the request rate or quota is exceeded, the API returns a 429 Too Many Requests error.

Error Example

{
  "code": "too_many_requests",
  "message": "You've exceeded the maximum amount of allowed requests. Please try again later."
}

Best practices

Implement exponential backoff or fixed retry delays when handling 429 errors.

Keep track of your own request counts to avoid hitting the monthly quota unexpectedly.
