OpenAPIToolkit

class OpenAPIToolkit:

A class representing a toolkit for interacting with OpenAPI APIs.

This class provides methods for interacting with APIs based on OpenAPI specifications. It dynamically generates functions for each API operation defined in the OpenAPI specification, allowing users to make HTTP requests to the API endpoints.

​
parse_openapi_file

def parse_openapi_file(self, openapi_spec_path: str):

Load and parse an OpenAPI specification file.

This function utilizes the prance.ResolvingParser to parse and resolve the given OpenAPI specification file, returning the parsed OpenAPI specification as a dictionary.

Parameters:

  • openapi_spec_path (str): The file path or URL to the OpenAPI specification.

Returns:

Optional[Dict[str, Any]]: The parsed OpenAPI specification as a dictionary. :obj:None if the package is not installed.

​
openapi_spec_to_openai_schemas

def openapi_spec_to_openai_schemas(self, api_name: str, openapi_spec: Dict[str, Any]):

Convert OpenAPI specification to OpenAI schema format.

This function iterates over the paths and operations defined in an OpenAPI specification, filtering out deprecated operations. For each operation, it constructs a schema in a format suitable for OpenAI, including operation metadata such as function name, description, parameters, and request bodies. It raises a ValueError if an operation lacks a description or summary.

Parameters:

  • api_name (str): The name of the API, used to prefix generated function names.
  • openapi_spec (Dict[str, Any]): The OpenAPI specification as a dictionary.

Returns:

List[Dict[str, Any]]: A list of dictionaries, each representing a function in the OpenAI schema format, including details about the function’s name, description, and parameters.

Note:

This function assumes that the OpenAPI specification follows the 3.0+ format.

openapi_function_decorator

def openapi_function_decorator(
    self,
    api_name: str,
    base_url: str,
    path: str,
    method: str,
    openapi_security: List[Dict[str, Any]],
    sec_schemas: Dict[str, Dict[str, Any]],
    operation: Dict[str, Any]
):

Decorate a function to make HTTP requests based on OpenAPI specification details.

This decorator dynamically constructs and executes an API request based on the provided OpenAPI operation specifications, security requirements, and parameters. It supports operations secured with apiKey type security schemes and automatically injects the necessary API keys from environment variables. Parameters in path, query, header, and cookie are also supported.

Parameters:

  • api_name (str): The name of the API, used to retrieve API key names and URLs from the configuration.
  • base_url (str): The base URL for the API.
  • path (str): The path for the API endpoint, relative to the base URL.
  • method (str): The HTTP method (e.g., ‘get’, ‘post’) for the request.
  • openapi_security (List[Dict[str, Any]]): The global security definitions as specified in the OpenAPI specs.
  • sec_schemas (Dict[str, Dict[str, Any]]): Detailed security schemes.
  • operation (Dict[str, Any]): A dictionary containing the OpenAPI operation details, including parameters and request body definitions.

Returns:

Callable: A decorator that, when applied to a function, enables the function to make HTTP requests based on the provided OpenAPI operation details.

​
generate_openapi_funcs

def generate_openapi_funcs(self, api_name: str, openapi_spec: Dict[str, Any]):

Generates a list of Python functions based on OpenAPI specification.

This function dynamically creates a list of callable functions that represent the API operations defined in an OpenAPI specification document. Each function is designed to perform an HTTP request corresponding to an API operation (e.g., GET, POST) as defined in the specification. The functions are decorated with openapi_function_decorator, which configures them to construct and send the HTTP requests with appropriate parameters, headers, and body content.

Parameters:

  • api_name (str): The name of the API, used to prefix generated function names.
  • openapi_spec (Dict[str, Any]): The OpenAPI specification as a dictionary.

Returns:

List[Callable]: A list containing the generated functions. Each function, when called, will make an HTTP request according to its corresponding API operation defined in the OpenAPI specification.

​
apinames_filepaths_to_funs_schemas

def apinames_filepaths_to_funs_schemas(self, apinames_filepaths: List[Tuple[str, str]]):

Combines functions and schemas from multiple OpenAPI specifications, using API names as keys.

This function iterates over tuples of API names and OpenAPI spec file paths, parsing each spec to generate callable functions and schema dictionaries, all organized by API name.

Parameters:

  • apinames_filepaths (List[Tuple[str, str]]): A list of tuples, where each tuple consists of: - The API name (str) as the first element. - The file path (str) to the API’s OpenAPI specification file as the second element.

Returns:

Tuple[List[Callable], List[Dict[str, Any]]]:: one of callable functions for API operations, and another of dictionaries representing the schemas from the specifications.

​
generate_apinames_filepaths

def generate_apinames_filepaths(self):

Returns:

List[Tuple[str, str]]: A list of tuples where each tuple contains two elements. The first element of each tuple is a string representing the name of an API, and the second element is a string that specifies the file path to that API’s OpenAPI specification file.

​
get_tools

def get_tools(self):

Returns:

List[FunctionTool]: A list of FunctionTool objects representing the functions in the toolkit.
