Definition
Search API rate limiting is the practice of restricting how many requests a client can make within a given time window, used by search API providers to prevent abuse, ensure fair usage, and maintain service stability.
In Depth
Rate limiting in search APIs typically works through request quotas measured in requests per second (RPS), per minute, or per month. When a client exceeds the limit, the API returns HTTP 429 (Too Many Requests) with a Retry-After header. Production-grade search APIs implement tiered rate limits based on plan level -- free tiers might allow 1 RPS while paid plans allow 10-50 RPS. Developers need to handle rate limits gracefully using exponential backoff, request queuing, and concurrent request pooling. Credit-based APIs like Scavio simplify this by decoupling rate limits from billing: you buy a monthly credit pool and can use credits at whatever pace the rate limit allows, making cost prediction straightforward. Understanding rate limits is critical for batch operations like rank tracking where thousands of queries need to complete within a time window.
Example Usage
A rank tracking tool sends 5,000 queries per hour to Scavio's API. The tool implements a request queue with exponential backoff that automatically retries on 429 responses, ensuring all queries complete without data loss even during peak usage.
Platforms
Search API Rate Limiting is relevant across the following platforms, all accessible through Scavio's unified API:
