Installation

pip install pangolinfo-niche-data

Quick start

from pangolinfo_niche_data import NicheDataClient

client = NicheDataClient(token="your_bearer_token")

# Browse the category tree
children = client.get_category_children(parent_browse_node_id_path="2619526011")

# Search categories by keyword (English and Chinese)
hits = client.search_categories("coffee")

# Resolve full paths for a list of category IDs
paths = client.batch_category_paths(["2619526011", "172282"])

# Filter categories by marketplace + metrics
result = client.filter_categories(
    marketplace_id="ATVPDKIKX0DER",
    time_range="T360",
    sample_scope="CATEGORY",
    unit_sold_sum_min=1000,
    sort_field="unitSoldSum",
    sort_order="desc",
    size=10,
)

# Discover blue-ocean niches
niches = client.filter_niches(
    marketplace_id="ATVPDKIKX0DER",
    search_volume_t90_min=5000,
    minimum_price=15,
    maximum_price=50,
    size=10,
)

client.close()

The client is also usable as a context manager:

with NicheDataClient(token="your_bearer_token") as client:
    print(client.search_categories("coffee"))

Authentication

All requests are authenticated with a Bearer token sent in the Authorization header. Get a free API key at tool.pangolinfo.com.

client = NicheDataClient(token="your_bearer_token")

Base URL

http://scrapeapi.pangolinfo.com/api/v1

Every endpoint is reached via POST. Responses follow the shape:

{ "code": 0, "message": "ok", "data": { ... } }

A non-zero code is raised as an APIError.

Methods

Python methods use idiomatic snake_case parameter names. They are converted to the API's camelCase JSON keys automatically (e.g. parent_browse_node_id_path → parentBrowseNodeIdPath). None values are omitted from the request body.
