Real Estate Data Provider API Comparison

How deep is the pool of real estate data capture?

Recently, a friend of the second-hand real estate platform told me that their technical team stayed up for three weeks and failed to capture the house price data of a real estate website. Either the IP is blocked or the data is messed up, and finally they can only spend money to buy a ready-made API, but there are various real estate data providers on the market, and it's really a big headache to choose which one to use.

The fatal flaws of the four main APIs

Let's take the actual case. A startup team compared four mainstream suppliers on the market and found that 80% of these pits you have also stepped on:

To put it bluntly.Self-built crawlers are the cost-effective choiceBut there is a dead end here: the more upgraded the anti-climbing mechanism of the website, the more proxy IP resources are needed. There is a school district housing analysis of buddies, began to use a free proxy, the results of three days and two times the data out of gear, and then changed the dynamic residential IP to stabilize.

A well-chosen proxy IP will keep the data bowl in place.

Here's a trick for you:Look at the "freshness" of the IP pool. Good proxy service has to be like fresh food delivery, IP survival time control in the best 5-15 minutes. Last year, there was a team doing house price prediction modeling, using a certain service provider that claimed to have ten million IP pools, and as a result, the same IP had not been changed for half an hour, and was directly blacklisted by the target website.

It's time to recommend ouripipgo Dynamic Residential ProxyThe IP survival cycle is intelligently designed. Their IP survival cycle is intelligently designed - it is intelligently adjusted according to the strength of the wind control of the target site, such as the chain of strict control sites automatically switch the frequency, while ordinary sites extend the IP use time to help users save costs.

A practical guide to avoiding the pit

Don't be in a hurry, remember these three points first:

1. Higher concurrency is not better: An apartment operator set 50 requests per second at first, which resulted in triggering website DDoS protection. Later, using ipipgo's intelligent speed regulation function, according to the response code automatically reduce the frequency, the data acquisition rate instead of improving 40%

2. Don't save money on header verification: Some vendors omit HTTP header fingerprinting emulation in order to reduce prices. During last year's Double Eleven, a price comparison platform was identified as machine traffic because of this

3. Geographic location should be precise to the district: Anyone who does school district housing analysis knows that home price data for Chaoyang and Haidian districts must be obtained in separate IPs. ipipgo supportDistrict IP PositioningIt's a lot more reliable than the ones that only cut to the city level.

You ask, I answer.

Q: Why do I have to use a proxy IP to build my own crawler?
A: Now the real estate website are installed with intelligent wind control, the same IP continuous access to the light flow restriction, the heavy permanent ban. The use of dynamic IP is equivalent to the crawler wearing a myriad of "human skin masks".

Q: How do I choose between a residential agent and a server room agent?
A: Residential IP is closer to the real user, like ipipgo's residential IP library access to home broadband resources, over the real estate website's wind control than the server room IP is more than ten times easier!

Q: What's unique about ipipgo?
A: Their homeScenario-based routingThe function is perfect! You can preset IP switching strategies for different real estate websites, for example, set Shell Housing to change IP every 5 minutes and Anjuke to change IP every 20 requests.

Q: Can't I use the free agent?
A: Last year, there was a bloody case: a startup company used a free proxy to capture house price data, but the result was that the IP pool was mixed with labeled malicious IPs, which led to the nullification of the entire data sample and the direct loss of bidding opportunities.

In the end, picking the right proxy IP service provider is insurance for your data business. A service provider like ipipgo that understands both technology and industry pain points is definitely a secret weapon for real estate data players. Next time your tech team is worried about blocking IPs, remember that there is a service provider who canIntelligent number raising, precise positioning, real-time freshnessThe solution awaits.
