oxapi 1.1.3

The Python library for querying the OxAPI

This Python library provides simplified access to the OxAPI from applications written in Python.

import oxapi
oxapi.api_key = "sk-..."

encoding = oxapi.Encoding.run(
    model="all-mpnet-base-v2",
    texts=["Hello", "How are you?"]
)

The OxAPI offers a variety of models from natural language processing for your convenience.

We provide highly optimized and production-ready endpoints to serve artificial intelligence for your deep tech applications.

Hosting and running such models is very difficult and time-consuming. At OxAPI, you get all the latest NLP technology for building applications without any of the inconveniences that come with it.

We provide open-source and proprietary models with transparent and fair pricing as high-performance endpoints. Each model is documented in detail and offers an easy-to-use and understandable API. We take care of hosting, hardware selection, and optimization for you. The results are some of the fastest models on the market. OxAPI, from developers, for developers.

Usage

API key

The library needs to be configured with your account's secret key. Either set it as the OXAPI_KEY environment variable before using the library:

export OXAPI_KEY='sk-...'

Or set oxapi.api_key to its value:

import oxapi
oxapi.api_key = "sk-..."

Completion

from oxapi import Completion

# Performing API call

completion = Completion.run(
    model="gpt-neo-2-7b", 
    prompt="My name is Tim.\nSentiment: Neutral\nIt is such a lovely day.\nSentiment: Positive\nAlthough I am in a bad mood\nSentiment:",
    max_length=2, 
    do_sample=False, 
    eos_words=["\n"]
)

# Fetching result

res = completion.format_result(result_format="str")

print(completion.result)

Output:

{'results': ['Neutral\n']}

Classification

from oxapi import Classification

# Performing API call

classification = Classification.run(
    model="dialog-content-filter", 
    texts=["I want to kill myself.", "I want to kill myself.<sep>You should not do that!", "I want to kill myself.<sep>Do it!"]
)

# Fetching result

res = classification.format_result(result_format="pd")

print(res)

Output:

                                                text label          confidence_score

2                  I want to kill myself.<sep>Do it!  unsafe      0.9266854663680397

Encoding

from oxapi import Encoding

# Performing API call

encoding = Encoding.run(
    model="all-mpnet-base-v2",
    texts=["Hello", "How are you?"]
)

# Fetching result

print(encoding.result)

Output:

{'results': [[
   -0.017791748046875,
   -2.980232238769531e-07,
   -0.022003173828125,

}

Transformation

from oxapi import Transformation

# Performing API call

transformation = Transformation.run(
    model="punctuation-imputation", 
    texts=["hello my name is tim i just came back from nyc how are you doing"]
)

# Fetching result

# Performing API call

pipeline = Pipeline.run(
    model="en-core-web-lg",
    texts=["Hi there!"]
)

# Fetching result

print(pipeline.result)

     'dep': 'punct',
     'head': 0}],
   'sents_text': ['Hi there!']}]
}

Asynchronous call pipeline

With oxapi-python package is possible to make calls to OxAPI in parallel. The AsyncCallPipe class takes as input a list of API calls each set through the prepare function to be executed by the pipeline.

from oxapi.async import AsyncCallPipe

from oxapi import Completion
from oxapi import Classification
from oxapi import Transformation
from oxapi import Pipeline

# Set up API calls

cl = Classification.prepare(model="dialog-content-filter", texts=["I want to kill myself."])
cm = Completion.prepare(model="gpt-neo-2-7b", prompt="Hello there, ", max_length=25, do_sample=True, eos_words=["\n"])
tr = Transformation.prepare(model="punctuation-imputation", texts=["hello my name is tim i just came back from nyc how are you doing"])
pl = Pipeline.prepare(model="en-core-web-lg", texts=["Hi there!"])

# Building and running the asynchronous pipe

asy = AsyncCallPipe([cl, cm, tr, pl])
res = asy.run()

# Fetching the result of the first call in the list

print(res[0].format_result(result_format="pd"))

Output:

                                                text label          confidence_score
0                             I want to kill myself.  unsafe      0.9772329101403038

It is possible to add API calls to the asynchronous pipe even after its instantiation though the add function. There's also the flush function to clear the list in the pipe.

from oxapi.async import AsyncCallPipe
from oxapi import Encoding

# Instantiate an empty asynchornous pipe

asy = AsyncCallPipe()

# Set up API call and add it to the pipe

en = Encoding.prepare(model="all-mpnet-base-v2", texts=["Hello", "How are you?"])
asy.add(en)

# running the asynchronous pipe

res = asy.run()
