Providing this parameter allows the API to incorporate visual data into the search. If both `image` and `prompt` are included, they are combined to refine the search. | | **prompt** | `string` | A natural language question or statement that specifies the information you are seeking. The prompt can include specific instructions about the expected answer type, timeframe, or content source. | | **source_blacklist** | `array` of `string` (optional) | A list of URLs or domains (e.g., `"expedia.com"`) that should be excluded from the search results. Cannot be used together with source_whitelist. | | **source_whitelist** | `array` of `string` (optional) | A list of URLs or domains that should be exclusively used in the search results. Cannot be used together with source_blacklist. | | **output_format** | `object` (optional) | A JSON object that specifies the expected structure of the response. This allows for control over the format and detail level of the results, making integration into structured applications seamless. See details below. | #### `output_format` Parameter The `output_format` parameter is a JSON object that defines the desired structure of the API response. Each key in this object represents a field in the response, and the value defines its data type or structure. ##### Supported Data Types - **Primitive Types**: `"string"`, `"number"`, `"boolean"` - **Nested Objects**: An object can have other fields, each with types or nested structures. - **Arrays of Objects**: Arrays can contain objects with defined structures. ##### Example of `output_format` ```json { "flights": [ { "destination": "string", "price": "number", "date": "string" } ], "summary": "string", "isAvailable": "boolean" } ``` In this example: - `flights` is an array where each object has `destination` (a string), `price` (a number), and `date` (a string). - `summary` is a single string. - `isAvailable` is a boolean value. ##### Request Example Here's an example request using the parameters defined: ```json { "image": "https://cdn.britannica.com/95/94195-050-FCBF777E/Golden-Gate-Bridge-San-Francisco.jpg", "prompt": "What are the current flight prices to this location from Hong Kong?", "source_blacklist": ["expedia.com"], "output_format": { "flights": [ { "destination": "string", "price": "number", "date": "string" } ], "response": "string" } } ``` In this request: - `image` provides an image URL. - `prompt` specifies the information sought. - `source_blacklist` excludes results from `"expedia.com"`. - `output_format` requests a structured response with `flights` (each with `destination`, `price`, and `date`) and an additional `response` as a summary string. #### Response The API returns a JSON object formatted according to the `output_format`, providing flexibility in structuring the data based on application needs. termsOfService: https://api.critique-labs.ai/en/docs/terms-of-service contact: email: support@critique-labs.ai version: 1.5.0 x-logo: url: >- https://critique-labs.ai/_next/image?url=%2Fimages%2Ficon_only.png&w=96&q=75 servers: - url: https://api.critique-labs.ai - url: http://localhost security: [] paths: /v1/contents: post: summary: Contents description: >- This endpoint is used to retrieve the post-processed contents of a web page in the format that the agentic search engine processes. operationId: contents_v1_contents_post requestBody: content: application/json: schema: $ref: '#/components/schemas/ContentRequest' required: true responses: '200': description: Successful Response content: application/json: schema: $ref: '#/components/schemas/ContentOutput' '422': description: Validation Error content: application/json: schema: $ref: '#/components/schemas/HTTPValidationError' security: - api_key: [] components: schemas: ContentRequest: properties: url: type: string title: Url description: The url of the web page you want to retrieve the contents of query: anyOf: - type: string - type: 'null' title: Query description: Optional, a query to be used to search the contents of the url type: object required: - url title: ContentRequest ContentOutput: properties: response: type: string title: Response info: anyOf: - type: object - type: 'null' title: Info default: {} type: object required: - response title: ContentOutput HTTPValidationError: properties: detail: items: $ref: '#/components/schemas/ValidationError' type: array title: Detail type: object title: HTTPValidationError ValidationError: properties: loc: items: anyOf: - type: string - type: integer type: array title: Location msg: type: string title: Message type: type: string title: Error Type type: object required: - loc - msg - type title: ValidationError securitySchemes: api_key: type: apiKey description: >- Your API key for authentication.
