I am looking for someone to build a Java API to enable interaction with a particular website. I will reveal the details of the site and API spec to those who contact me but for the sake of getting a better idea about the project, one could think of the site as a kind of auction site. The API would need to: 1. “Login” to the site to establish an authenticated session. Subsequent API calls should use those session credentials rather than re-login on each call. 2. Enumerate the list of outstanding auctions. The enumeration would contain: a. human readable name of the auction b. site ID for the auction c. verbose description for the auction d. expiry for the auction 3. Given a site auction ID enumerate the outstanding bids made by participants 4. Given a site auction ID make a bid on the auction 5. Given a site auction ID enumerate the bid(s) made by the user (API) on that auction. The enumeration would include a. price b. a bid ID c. status 6. Given a bid ID query the status which could be: a. won b. lost c. pending. 7. The API must be thread-safe i.e. reentrant allowing multiple threads to make parallel request on both the same and different login ID’s and locking should be minimal to allow a high degree of parallelism 8. Should optionally be able to direct requests through a standard http(s) proxy server which should be configurable on a per-session (i..e per login) basis. 9. Note that this is a 2.0 web site so the project will be more involved that just parsing HTML for links and calling those. 10. I assume there are Java automation frameworks to assist this with (example [login to view URL]) 11. I have a strong preference towards Java for this but could be convinced to accept a python implementation provided that the implementation included a SOAP interface and a Java stubs to call the API via SOAP. The above is “rough” and the actual project from a programming perspective should be similar in scope to the above but some pretty big differences. I’m looking for someone who has: a. experience building applications that scrape/control website programatically b. many years experience developing java applications - I’ve been developing in Java for years and will know right a way if this is one of your first Java programs (even if it works perfectly) and most likely give you a bad review. b. is able to complete the project for $200 (I will consider paying a bonus for exceptional work) If interested, please send me a message outlining relevant project experience and I’ll send specifics about the site and API.

Hi there. As I understand, you want to build an interface as if it was a real API provided by the site's owner, but instead the API will use scraping techniques to communicate to the server via their webpage. I specialize in web scraping but I always use the Scrapy framework, which is written in Python. Either way, this means I'm proficient in all the technologies required for scraping as HTTP, HTML, CSS selectors, AJAX, regular expressions, etc. On the other hand, I have worked with Java for many years (I can show you some open source projects I have); just not for web scraping. I would gladly study a Java framework for HTML parsing (jsoup definitely seems to be the most popular one) for your project, but this might mean that I will need a little more time than someone who already works with web scraping in Java. Anyway, feel free to contact me.
