# SerpApi Rate Limits ## Overview SerpApi uses credit-based pricing (each search = 1 credit) plus per-second rate limits. Retrieving cached/archived searches does not consume credits. Plans range from 100 searches/month (free) to unlimited (enterprise). ## Plan Limits | Plan | Searches/Month | Rate Limit | Price | |------|---------------|------------|-------| | Free | 100 | 1/second | $0 | | Developer | 5,000 | 5/second | $75/mo | | Business | 15,000 | 10/second | $200/mo | | Enterprise | 50,000+ | 15/second | Custom | ## Instructions ### Step 1: Monitor Credit Usage ```python import serpapi, os client = serpapi.Client(api_key=os.environ["SERPAPI_API_KEY"]) # Check remaining credits before batch operations account = client.account() remaining = account["plan_searches_left"] used = account["this_month_usage"] total = account["total_searches_left"] print(f"Used: {used}, Remaining: {remaining}") if remaining < 100: print("WARNING: Low credits remaining") ``` ### Step 2: Request Throttling ```python import time from threading import Semaphore class ThrottledSerpApi: def __init__(self, api_key: str, max_per_second: int = 5): self.client = serpapi.Client(api_key=api_key) self.semaphore = Semaphore(max_per_second) self.last_request = 0 def search(self, **params) -> dict: with self.semaphore: # Enforce minimum interval elapsed = time.time() - self.last_request if elapsed < 0.2: # 5/sec max ...
