CompTox API key (optional, will be loaded from config if not provided) |
None
|
base_url
|
str
|
Base URL for the CompTox API |
'https://comptox.epa.gov/ctx-api/'
|
time_delay_between_calls
|
float
|
Delay between API calls in seconds |
0.0
|
Raises:
| Type | Description |

list_all_puc_product(use_cache=None)
¶
Get all Product Use Category (PUC) classifications.
Retrieves a complete list of Product Use Category (PUC) codes and their definitions. PUCs provide a hierarchical classification system for categorizing consumer product types based on their use and function.
Returns:
| Type | Description |
|---|---|
List[Dict[str, Any]]
|
List of dictionaries containing PUC information including codes, |
List[Dict[str, Any]]
|
descriptions, and hierarchical relationships. |
Example
prod_data = ProductData() pucs = prod_data.list_all_puc_product() for puc in pucs: ... print(f"{puc.get('pucCode', 'N/A')}: {puc.get('pucDescription', '')}")
Source code in src/pycomptox/exposure/productdata.py
product_data_by_dtxsid_batch(dtxsid_list, use_cache=None)
¶
Get product data for multiple chemicals in a single request.
Retrieves product information for multiple chemicals at once using a batch API call. This is more efficient than making individual requests for each chemical when working with multiple DTXSIDs.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
dtxsid_list
|
List[str]
|
List of DSSTox Substance Identifiers |
required |
Returns:
| Type | Description |
|---|---|
List[Dict[str, Any]]
|
List of dictionaries containing product data for all requested chemicals. |
List[Dict[str, Any]]
|
Results include the DTXSID and associated product information for each |
List[Dict[str, Any]]
|
chemical. |
Raises:
| Type | Description |
|---|---|
ValueError
|
If dtxsid_list is not a valid non-empty list |
Example
prod_data = ProductData() dtxsids = ["DTXSID0020232", "DTXSID7020182"] batch_results = prod_data.product_data_by_dtxsid_batch(dtxsids) for result in batch_results: ... print(f"{result.get('dtxsid')}: {result.get('productName')}")
Source code in src/pycomptox/exposure/productdata.py
products_data_by_dtxsid(dtxsid, use_cache=None)
¶
Get product data for a chemical.
Retrieves information about consumer products that contain a specific chemical identified by its DSSTox Substance Identifier (DTXSID). This includes product names, manufacturers, product use categories (PUC), and composition information.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
dtxsid
|
str
|
DSSTox Substance Identifier (e.g., 'DTXSID0020232') |
required |
Returns:
| Type | Description |
|---|---|
List[Dict[str, Any]]
|
List of dictionaries containing product data. Each entry includes product |
List[Dict[str, Any]]
|
information such as name, manufacturer, PUC classification, and chemical |
List[Dict[str, Any]]
|
composition details. |
Raises:
| Type | Description |
|---|---|
ValueError
|
If dtxsid is not a valid non-empty string |
Example
prod_data = ProductData() products = prod_data.products_data_by_dtxsid("DTXSID0020232") for product in products: ... print(f"{product.get('productName', 'N/A')}: {product.get('pucCode', 'N/A')}")
