jaat-api 0.3.0

Official lightweight client wrapper library for the JAAT API.

jaat-api

The official, lightweight Python client library for the JAAT suite of tools.

jaat-api is an easy-to-use, intuitive, session-managed SDK for programtically accessing the open-source JAAT modules. This tool works great for integrating JAAT into your workflows or applications, and it enablings accessing JAAT with running it locally!

---

Installation

Install directly from PyPI:

pip install jaat-api

Quick Start

Initialize the JAATClient with your API key (provided by us) and execute JAAT on your batch texts seamlessly:

from jaat_api import JAATClient

client = JAATClient(api_key="jaat_app_private_key_here")

job_ads = [
    "[JOB AD TEXT 1]",
    "[JOB AD TEXT 2]",
    "..."
]

task_results = client.run_batch("task", job_ads) # alternatively, client.get_tasks_batch(job_ads)

# continue to run other jobs
skill_results = client.run_batch("skill", job_ads)

Of course, you can also use the client to process single texts:

task_result = client.run("task", job_ads[0]) # alternatively, client.get_tasks(job_ads)

skill_result = client.run("skill", job_ads[0])

Helpful Tips

Currently Supported JAAT Modules

As of the current version of jaat-api, the following JAAT modules are supported:

Supported from Version:	jaat-api ID	JAAT Module
0.1.0	task	TaskMatch
0.1.0	skill	SkillMatch
0.1.0	ai	AIMatch
0.2.0	title	TitleMatch

The API is currently running JAAT:

Handling Exceptions

The SDK provides a structured JAATError instance whenever an operation breaks down or fails. Ideally, wrap jobs within try/except blocks to handle these conditions gracefully:

from jaat_api import JAATError

try:
    ## as before
except JAATError as e:
    print(f"Extraction failed (Status Code: {e.status_code})")
    print(f"Error Context: {e.message}")

Sandbox Public Evaluation

Anyone looking to evaluate the platform programmatically before contacting us for a dedicated token can use the public sandbox key:

client = JAATClient(api_key="jaat_public_sandbox_testing_key")

try:
    results = client.get_tasks(["JOB AD TEXT"])
    print(results)
except JAATError as e:
    if e.status_code == 429:
        print("Sandbox daily evaluation volume exhausted. Please rotate to a private key.")

As can be seen, the public API key is highly throttled and is strictly for testing purposes. The current usage of this key is limited to one request per day, per IP.
