Intelligent Market Monitoring

The pipeline for monitoring the market has the folling main steps:

1. search for a given term using SerpAPI
2. get product information using ZyteAPI
3. assess relevance of the found products using an OpenAI API

Installation

python3.11 -m venv .venv
source .venv/bin/activate
pip install vianu-fraudcrawler

Usage

.env file

Make sure to create an .env file with the necessary API keys and credentials (c.f. .env.example file).

Run demo pipeline

python -m fraudcrawler.launch_demo_pipeline

Customize the pipeline

Start by initializing the client

from fraudcrawler import FraudCrawlerClient

# Initialize the client
client = FraudCrawlerClient()

For setting up the search we need 5 main objects

• search_term: The search term for the query.
• language: The Language used in SerpAPI ('hl') and for related search terms (within optional enrichement)
• location: The SerpAPI location ('gl') used for the query.
• deepness: Defines the search depth.
• context: The context prompt to use for detecting relevant products

from fraudcrawler import Language, Location, Deepness
# Setup the search
search_term = "sildenafil"
language = Language(name="German")
location = Location(name="Switzerland")
deepness = Deepness(num_results=50)
context = "This organization is interested in medical products and drugs."

(Optional) Add search term enrichement. This will find related search terms (in a given language) and search for these as well.

from fraudcrawler import Enrichment
deepness.enrichment = Enrichment(
    additional_terms=5,
    additional_urls_per_term=10
)

(Optional) Add marketplaces where we explicitely want to look for (this will focus your search as the :site parameter for a google search)

from fraudcrawler import Host
marketplaces = [
    Host(name="International", domains="zavamed.com,apomeds.com"),
    Host(name="National", domains="netdoktor.ch, nobelpharma.ch"),
]

(Optional) Exclude urls (where you don't want to find products)

excluded_urls = [
    Host(name="Compendium", domains="compendium.ch"),
]

And finally run the pipeline

# Execute the pipeline
client.execute(
    search_term=search_term,
    language=language,
    location=location,
    deepness=deepness,
    context=context,
    # marketplaces=marketplaces,    # Uncomment this for using marketplaces
    # excluded_urls=excluded_urls   # Uncomment this for using excluded_urls
)

This creates a file with name pattern <search_term>_<datetime[%Y%m%d%H%M%S]>.csv inside the folder data/results/.

Once the pipeline terminated the results can be loaded and examined as follows:

df = client.load_results()
print(df.head(n=10))

If the client has been used to run multiple pipelines, an overview of the available results (for a given instance of FraudCrawlerClient) can be obtained with

client.print_available_results()
