gen_ai_hub.evaluations.credentials.get_nested_value(data_dict, keys: List[str])

Retrieve a nested value from a dictionary using a list of strings.

Parameters:

• data_dict – The dictionary to search.

• keys – A list of strings representing nested keys.

Returns:

The value associated with the nested keys, or None if not found.

gen_ai_hub.evaluations.credentials.extract_credentials(source: Source, exclude: List[str] = None) → Dict[str, str]

Extract all credentials from a source.

gen_ai_hub.evaluations.credentials.resolve_credentials(sources: List[Source]) → Dict[str, str]

Extract credentials from the first source that has any defined.

gen_ai_hub.evaluations.credentials.resolve_resource_group(sources: List[Source]) → str | None

Find resource_group from the first source that defines it.

gen_ai_hub.evaluations.credentials.validate_credentials(credentials: Dict[str, str]) → None

Validate that we have a complete authentication method.

gen_ai_hub.evaluations.credentials.fetch_credentials(profile: str = None, **kwargs) → Dict[str, str]

Fetch credentials from a single source based on precedence.

Precedence order: kwargs > environment variables > config file > VCAP service

Once a source is selected (first one with any credential), all credentials come from that source only. Resource group is an exception and follows precedence independently.
