Haskell API Client for Clarifai.
Clarifai provides image/video recognition services, and this library provides a web client to their API.
All endpoints other than the feedback endpoint are implemented. This includes - /info - /token - /tag
cabal install clarifai
First create an
`App and then call the authorize` function to authenticate your application. You must provide your client id and client secret.
import Network.Clarifai import Data.Either clientID = "id" clientSecret = "secret" main = do let myApp = App clientID clientSecret resp <- authorize myApp
Then you can check the response for errors, or use the access token it provides back in the form of a
Getting API Info
-- Omitted previous code main = do -- Be sure to check for errors let client = head $ rights [resp] infoResponse <- info client
If there are no errors, you will get back an
`Info` containing various information about the statistics and limits of the Clarifai API, like maximum video size, maximum image size, etc. You can use this verify any files you may want to tag, before you send a tagging request.
When going to verify batch sizes, it is important not to mix and match between videos and images. The batch sizes for images and videos are different, so you cannot verify the sizes of the batches together even though you can send them in the same request. I don't do any differentiating between what kind of file the
`FilePath` points to.
If you are calling the
`verifyFiles function, however, you can have a list of both videos AND images, as long as the extensions of each FilePath` indicate the type of the file.
-- Omitted previous code main = do -- Be sure to check for errors let apiInfo = head $ rights [infoResponse] let filePaths = [filePath1, filePath2, filePath3] -- Verify the image batch size -- The return value is a Bool indicating whether your list is of appropriate size for the API. verifyImageBatchSize apiInfo filePaths -- Verify the sizes of the files in the list. As long as each FilePath indicates whether the file is a video or an image, -- the size of the file will be checked to make sure it is within the appropriate bounds according to the API Info. verifyFiles infoData fileNames
We can send a tag request with our list of
`FilePath`s. I've omitted any steps where we may have filtered out which files
```haskell -- Omitted previous code tagResponse <- tag client fileNames
I'll gladly take contributions/improvements/pull requests.
