The cost per GB-second is $0.00001667, and transcoding a minute of audio with the function that we’ll develop requires just shy of 5 GB-seconds.INTOLI

RESIDENTIAL PROXIES
All traffic is routed through clean residential IP addresses that allow you to scrape at high volumes while avoiding detection.__
INTELLIGENT REQUEST ROUTING We employ cutting edge machine learning techniques to automatically route your requests through IP addresses that are the least likely tobe blocked.
__
AUTOMATIC REQUEST RETRIES When requests do fail, we’ll automatically retry them through alternative IP addresses until we find one that gets you the data youneed.
__
HEADLESS BROWSERS
Optionally render HTML responses in headless browsers which support JavaScript and are preconfigured to bypass common bot-mitigationstrategies.
__
PERSISTENT SESSIONS
You can either manage your sessions locally, or persist all cookies and local storage on our infrastructure. Easily support logins, and other cookie-based interactions.__
EASILY CONFIGURABLE
Each feature is completely configurable on a per-project basis. You can generate a custom proxy URL for each project, and selectively enable features based on the project’s needs.TESTIMONIALS
We’ve worked with many clients and we do everything we can to make sure they’re happy with the results. Have a look at what some of them have said about us.*
I first came across Intoli after reading some of their articles on web scraping, which are excellent. I thoroughly recommend them for anyone learning Scrapy and web scraping in general!__

I had been wanting to make Pointy Ball for years but it wasn’t until I talked to Intoli that I found people who could actually make it a reality. They aggregated data from all over and were able to add functionality to the ESPN site to an extent that I didn’t think waspossible.
If you need something done, and you’re not even sure it’s possible, then these are your guys!__

Evan was awesome to work with. He was really good at multitasking across our whole stack and he tore through some very difficult problems in no time… like scary fast in some cases. He’s an excellent developer and I couldn’t recommend him more.__
ANGELO GOMEZ
Lead Engineer, Fourmation Inc*
Andre operated across the entire stack to develop a research-oriented web application with us. He worked against aggressive deadlines on everything from the backend and AWS devops, all the way to specifically architecting complex JavaScript applications that push the limits on browsers. Andre is a pleasure to work with and I would be happy to work with himagain.

Evan is a very knowledgeable and experienced data scientist and developer. We worked with him to build a core part of our algorithm. His communication before starting the project was great: he helped narrow down exactly what we were looking for so that we wouldn’t be billed for any extra hours. He hit every requirement with well-structured, maintainable code in just a few days, and gave us lots of support afterwards to get it fine-tuned for production. I will absolutely be reaching out to Intoli again for future projects.__

Evan has been an avid programmer for 19 years and has shipped projects in over a dozen languages. His career began in experimental higher energy physics where he managed distributed computing infrastructures and performed award winning research on particle identification. This work included the development of a ground breaking unsupervised machine learning technique that significantly outperformed all existing approaches. He later switched fields to statistics where he developed the strongly intensive cumulants and made the first Bayesian determination of the nuclear equation of state using advanced statistical techniques designed to accommodate otherwise prohibitively expensive models. Since leaving academia, he has founded a startup that used artificial intelligence to make video games more fun, written technical
articles that hundreds of thousands of people have enjoyed , and helped numerous companies build their products or meet their data needs. ANDRE PERUNICIC, PHD__ __
__
__
After getting his Ph.D. in math, Andre spent two years working as a postdoc at research institutions in Canada. His academic work centered on applying ideas from mathematical physics and string theory tonumber theory
,
and he developed techniques for greatly simplifying certain extremely labor intensivecalculations.
His mathematical training and life-long programming experience allowed for an easy transition to industry, where he has helped multiple teams meet their business and data science needs. He worked on desktop and web applications, as well as data science projects, and has a detailed understanding of machine learning algorithms and techniques. Before Intoli, he most recently worked in the data science department of Spreemo Health , where he used Bayesian techniques to define analytical metrics used to measure quality of radiology services. He helped identify key predictive factors for high quality MRI exams, and demonstrated drastic differences amongst various radiology providers.ABOUT US
