Package: ao3-api
AO3 APIThis is an unofficial API that lets you access some of AO3's (archiveofourown.org) data through Python.InstallationUse the package managerpipto install AO3 API.pipinstallao3_apiGithubhttps://github.com/ArmindoFlores/ao3_apiUsageThis package is divided in 9 core modules: works, chapters, users, series, search, session, comments, extra, and utils.WorksOne of the most basic things you might want to do with this package is loading a work and checking its statistics and information. To do that, you'll need theAO3.Workclass.We start by finding theworkidof the work we want to load. We do that either by usingAO3.utils.workid_from_url(url)or by just looking at the url ourselves. Let's take a look:importAO3url="https://archiveofourown.org/works/14392692/chapters/33236241"workid=AO3.utils.workid_from_url(url)print(f"Work ID:{workid}")work=AO3.Work(workid)print(f"Chapters:{work.nchapters}")After running this snippet, we get the output:Work ID: 14392692
Chapters: 46It's important to note that some works may not be accessible to guest users, and in this case you will get 0 chapters as an output, and the errorAO3.utils.AuthError: This work is only available to registered users of the Archiveif you try to load it. Nontheless, we can still do a lot more with this Work object: Lets try to get the first 20 words of the second chapter.importAO3work=AO3.Work(14392692)print(work.chapters[1].title)# Second chapter nametext=work.chapters[1].text# Second chapter textprint(' '.join(text.split(" ")[:20]))What Branches Grow Meaning

Christmas sucked this year, and Shoutoâ€™s got the black eye to prove it.
Things had started out well enough,The objects in work.chapters are of typeAO3.Chapter. They have a lot of the same properties as aWorkobject would.Another thing you can do with the work object is download the entire work as a pdf or e-book. At the moment you can download works as AZW3, EPUB, HTML, MOBI, and PDF files.importAO3work=AO3.Work(14392692)withopen(f"{work.title}.pdf","wb")asfile:file.write(work.download("PDF"))Advanced functionalityUsually, when you call the constructor for theWorkclass, all info about it is loaded in the__init__()function. However, this process takes quite some time (~1-1.5 seconds) and if you want to load a list of works from a series, for example, you might be waiting for upwards of 30 seconds. To avoid this problem, theWork.reload()function, called on initialization, is a "threadable" function, which means that if you call it with the argumentthreaded=True, it will return aThreadobject and work in parallel, meaning you can load multiple works at the same time. Let's take a look at an implementation:importAO3importtimeseries=AO3.Series(1295090)works=[]threads=[]start=time.time()forworkinseries.work_list:works.append(work)threads.append(work.reload(threaded=True))forthreadinthreads:thread.join()print(f"Loaded{len(works)}works in{round(time.time()-start,1)}seconds.")Loaded 29 works in 2.2 seconds.Theload=Falseinside theWorkconstructor makes sure we don't load the work as soon as we create an instance of the class. In the end, we iterate over every thread and wait for the last one to finish using.join(). Let's compare this method with the standard way of loading AO3 works:importAO3importtimeseries=AO3.Series(1295090)works=[]start=time.time()forworkinseries.work_list:work.reload()works.append(work)print(f"Loaded{len(works)}works in{round(time.time()-start,1)}seconds.")Loaded 29 works in 21.6 seconds.As we can see, there is a significant performance increase. There are other functions in this package which have this functionality. To see if a function is "threadable", either usehasattr(function, "_threadable")or check its__doc__string.To save even more time, if you're only interested in metadata, you can load a work with theload_chaptersoption set to False. Also, be aware that some functions (likeSeries.work_listorSearch.results) might return semi-loadedWorkobjects. This means that no requests have been made to load this work (so you don't have access to chapter text, notes, etc...) but almost all of its metadata will already have been cached, and you might not need to callWork.reload()at all.The last important information about theWorkclass is that most of its properties (like the number of bookmarks, kudos, the authors' names, etc...) are cached properties. That means that once you check them once, the value is stored and it won't ever change, even if those values change. To update these values, you will need to callWork.reload(). See the example below:importAO3sess=AO3.GuestSession()work=AO3.Work(16721367,sess)print(work.kudos)work.leave_kudos()work.reload()print(work.kudos)392
393UsersAnother useful thing you might want to do is get information on who wrote which works / comments. For that, we use theAO3.Userclass.importAO3user=AO3.User("bothersomepotato")print(user.url)print(user.bio)print(user.works)# Number of works publishedhttps://archiveofourown.org/users/bothersomepotato
University student, opening documents to write essays but writing this stuff instead. No regrets though. My Tumblr, come chat with -or yell at- me if you feel like it! :)
2SearchTo search for works, you can either use theAO3.search()function and parse the BeautifulSoup object returned yourself, or use theAO3.Searchclass to automatically do that for you.importAO3search=AO3.Search(any_field="Clarke Lexa",word_count=AO3.utils.Constraint(5000,15000))search.update()print(search.total_results)forresultinsearch.results:print(result)3074

To get more then the first 20 works, change the page number usingsearch.page=2SessionA lot of actions you might want to take might require an AO3 account. If you already have one, you can access those actions using an AO3.Session object. You start by logging in using your username and password, and then you can use that object to access restricted content.importAO3session=AO3.Session("username","password")print(f"Bookmarks:{session.bookmarks}")session.refresh_auth_token()print(session.kudos(AO3.Work(18001499,load=False))Bookmarks: 67
TrueWe successfully left kudos in a work and checked our bookmarks. Thesession.refresh_auth_token()is needed for some activities such as leaving kudos and comments. If it is expired or you forget to call this function, the errorAO3.utils.AuthError: Invalid authentication token. Try calling session.refresh_auth_token()will be raised.You can also comment / leave kudos in a work by callingWork.leave_kudos()/Work.comment()and provided you have instantiated that object with a session already (AO3.Work(xxxxxx, session=sess)or usingWork.set_session()). This is probably the best way to do so because you will run into less authentication issues (as the work's authenticity token will be used instead).If you would prefer to leave a comment or kudos anonymously, you can use anAO3.GuestSessionin the same way you'd use a normal session, except you won't be able to check your bookmarks, subscriptions, etc. because you're not actually logged in.CommentsTo retrieve and process comment threads, you might want to look at theWork.get_comments()method. It returns all the comments in a specific chapter and their respective threads. You can then process them however you want. Let's take a look:fromtimeimporttimeimportAO3work=AO3.Work(24560008)work.load_chapters()start=time()comments=work.get_comments(5)print(f"Loaded{len(comments)}comment threads in{round(time()-start,1)}seconds\n")forcommentincomments:print(f"Comment ID:{comment.id}\nReplies:{len(comment.get_thread())}")Loaded 5 comment threads in 1.8 seconds

Replies: 2Loading comments takes a very long time so you should try and use it as little as possible. It also causes lots of requests to be sent to the AO3 servers, which might result in getting the errorutils.HTTPError: We are being rate-limited. Try again in a while or reduce the number of requests. If that happens, you should try to space out your requests or reduce their number. There is also the option to enable request limiting usingAO3.utils.limit_requests(), which make it so you can't make more than x requests in a certain time window.
You can also reply to comments using theComment.reply()function, or delete one (if it's yours) usingComment.delete().ExtraAO3.extra contains the the code to download some extra resources that are not core to the functionality of this package and don't change very often. One example would be the list of fandoms recognized by AO3.
To download a resource, simply useAO3.extra.download(resource_name). To download every resource, you can useAO3.extra.download_all(). To see the list of available resources, useAO3.extra.get_resources().Contact infoFor information or bug reports please contactfrancisco.rodrigues0908@gmail.com.LicenseMIT
