openapi: 3.1.0 info: title: Opik REST Spans API description: "The Opik REST API is currently in beta and subject to change. If you have any questions or feedback about the APIs, please reach out on GitHub: https://github.com/comet-ml/opik.\n\nAll of the methods listed in this documentation are used by either the SDK or the UI to interact with the Opik server. As a result,\nthe methods have been optimized for these use-cases in mind. If you are looking for a method that is not listed above, please create\nand issue on GitHub or raise a PR!\n\nOpik includes two main deployment options that results in slightly different API usage:\n\n- **Self-hosted Opik instance:** You will simply need to specify the URL as `http://localhost:5173/api/` or similar. This is the default option for the docs.\n- **Opik Cloud:** You will need to specify the Opik API Key and Opik Workspace in the header. The format of the header should be:\n\n ```\n {\n \"Comet-Workspace\": \"your-workspace-name\",\n \"authorization\": \"your-api-key\"\n }\n ```\n\n The full payload would therefore look like:\n \n ```\n curl -X GET 'https://www.comet.com/opik/api/v1/private/projects' \\\n -H 'Accept: application/json' \\\n -H 'Comet-Workspace: ' \\\n -H 'authorization: '\n ```\n\n Do take note here that the authorization header value does not include the `Bearer ` prefix. To switch to using the Opik Cloud in the documentation, you can\n click on the edit button displayed when hovering over the `Base URL` displayed on the right hand side of the docs.\n" contact: name: Github Repository url: https://github.com/comet-ml/opik license: name: Apache 2.0 url: http://www.apache.org/licenses/LICENSE-2.0.html version: 1.0.0 servers: - url: http://localhost:5173/api description: Local server - url: https://www.comet.com/opik/api description: Opik Cloud tags: - name: Spans description: Span related resources paths: /v1/private/spans/{id}/comments: post: tags: - Spans summary: Add span comment description: Add span comment operationId: addSpanComment parameters: - name: id in: path required: true schema: type: string format: uuid requestBody: content: application/json: schema: $ref: '#/components/schemas/Comment' responses: '201': description: Created headers: Location: required: true style: simple schema: type: string example: ${basePath}/v1/private/spans/{spanId}/comments/{commentId} /v1/private/spans/{id}/feedback-scores: put: tags: - Spans summary: Add span feedback score description: Add span feedback score operationId: addSpanFeedbackScore parameters: - name: id in: path required: true schema: type: string format: uuid requestBody: content: application/json: schema: $ref: '#/components/schemas/FeedbackScore' responses: '204': description: No Content /v1/private/spans/batch: post: tags: - Spans summary: Create spans description: Create spans operationId: createSpans requestBody: content: application/json: schema: $ref: '#/components/schemas/SpanBatch_Write' responses: '204': description: No Content patch: tags: - Spans summary: Batch update spans description: Update multiple spans operationId: batchUpdateSpans requestBody: content: application/json: schema: $ref: '#/components/schemas/SpanBatchUpdate' responses: '204': description: No Content '400': description: Bad Request content: application/json: schema: $ref: '#/components/schemas/ErrorMessage' /v1/private/spans: get: tags: - Spans summary: Get spans by project_name or project_id and optionally by trace_id and/or type description: Get spans by project_name or project_id and optionally by trace_id and/or type operationId: getSpansByProject parameters: - name: page in: query schema: minimum: 1 type: integer format: int32 default: 1 - name: size in: query schema: minimum: 1 type: integer format: int32 default: 10 - name: project_name in: query schema: type: string - name: project_id in: query schema: type: string format: uuid - name: trace_id in: query schema: type: string format: uuid - name: type in: query schema: type: string enum: - general - tool - llm - guardrail - name: filters in: query schema: type: string - name: truncate in: query schema: type: boolean description: Truncate input, output and metadata to slim payloads default: false - name: strip_attachments in: query schema: type: boolean description: If true, returns attachment references like [file.png]; if false, downloads and reinjects stripped attachments default: false - name: sorting in: query schema: type: string - name: exclude in: query schema: type: string - name: search in: query schema: type: string description: Full-text search across span fields - name: from_time in: query schema: type: string description: Filter spans created from this time (ISO-8601 format). format: date-time - name: to_time in: query schema: type: string description: Filter spans created up to this time (ISO-8601 format).
