The Hidden Conundrum of DuckDuckGo Interface Calls
The biggest headache for the guys when messing with data using DuckDuckGo's API is theRequest Frequency Limit. This search engine is friendly to ordinary users, but its API interface is particularly sensitive to programmed access, many developers just connected to find the IP is ban. At this time there is a need for a different way of thinking - through the proxy IP to decentralize the request pressure.
Take a real case: an e-commerce company needs to capture product search data, and their own server is limited by half an hour of continuous access. Later they used ipipgo'sDynamic residential agent poolThe data collection efficiency is directly tripled by spreading the requests to 50 different IPs.
import requests
proxies = {
'http': 'http://username:password@gateway.ipipgo.com:9020',
'https': 'http://username:password@gateway.ipipgo.com:9020'
}
response = requests.get(
'https://api.duckduckgo.com/?q=test&format=json'.

The Hidden Costs Behind Official Pricing
Although DuckDuckGo claims to be a free API, there are three dark potholes in its actual use:
| Chargeable items | Standards of disclosure | Actual consumption |
|---|---|---|
| Number of requests per IP | No explicit limitations | Over 500 times a day will be blocked |
| response time | uncommitted | Over 3 seconds during peak hours |
| data integrity | Complete Returns | High-frequency requests drop data |
That's when ipipgo'sIntelligent Routing FunctionIt comes in handy. Their proxy nodes can automatically switch the optimal line to control the request delay within 800ms, which is much more stable than direct connection.
Practical Configuration Tips
Focus on three easily overlooked configuration details:
1. request header masquerading as: Don't use the default Python-Requests header, this is the recommended change:
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36',
'Accept-Language': 'en-US,en;q=0.9'
}
2. Failure Retry Mechanism: It is recommended to use the exponential backoff algorithm, with ipipgo's automatic IP change function, the success rate can be up to 98%
3. geolocalization strategyFor example, if you are searching for German products, you should choose ipipgo's Frankfurt node.
Frequently Asked Questions QA
Q: How do I break the 100,000 requests I need per day?
A: It is recommended to use ipipgo's enterprise-level package, which supports concurrent 500 IP rotation, and remember to set the random request interval in the code (0.5-1.2 seconds is best)
Q: What should I do if the API returns results that are suddenly slow?
A: eighty percent is triggered by the wind control, immediately deactivate the current IP. with ipipgoEmergency Refresh FunctionThe IP pool will be changed to a new IP pool within 5 seconds.
Q: Which agent do I choose if I need a long term stable connection?
A: recommend ipipgo'sLong-lasting static residential IPThe single IP can be used for 7 days, which is especially suitable for business scenarios that require a login state.
Cost Control Tips
Share a wild way to save money: break up high-frequency requests intoInstant Requests + Cache UpdatesTwo parts. Use ipipgo'straffic multiplexing function, data with low real-time requirements go cached, which saves 40% of API calls.
Lastly, a note to newbies: don't write dead proxy IPs in your code! We recommend using the one provided by ipipgo!Intelligent Dispatch InterfaceThe APIs are designed to automatically get a list of available IPs. There are ready-made code examples in their API documentation, so you can copy them directly and use them, which saves you a lot of work compared to tossing them yourself.
