Inputs are a natural-language objective and optional keyword queries. Source policies allow including or excluding specific domains and have configurable output sizes. The returned extended snippets contain dense, relevant information from relevant pages. - Result: ranked list with URL, title, and long text excerpts - name: Extract description: >- Extract returns excerpts or full content from one or more URLs. Inputs are a list of URLs and an optional search objective and keyword queries. The returned excerpts or full content is formatted as markdown and suitable for LLM consumption. - Result: excerpts or full content from the URL formatted as markdown - name: Tasks description: >- The Task API executes web research and extraction tasks. Clients submit a natural-language objective with an optional input schema; the service plans retrieval, fetches relevant URLs, and returns outputs that conform to a provided or inferred JSON schema. Supports deep research style queries and can return rich structured JSON outputs. Processors trade-off between cost, latency, and quality. Each processor supports calibrated confidences. - Output metadata: citations, excerpts, reasoning, and confidence per field Task Groups enable batch execution of many independent Task runs with group-level monitoring and failure handling. - Submit hundreds or thousands of Tasks as a single group - Observe group progress and receive results as they complete - Real-time updates via Server-Sent Events (SSE) - Add tasks to an existing group while it is running - Group-level retry and error aggregation - name: FindAll description: >- The FindAll API discovers and evaluates entities that match complex criteria from natural language objectives. Submit a high-level goal and the service automatically generates structured match conditions, discovers relevant candidates, and evaluates each against the criteria. Returns comprehensive results with detailed reasoning, citations, and confidence scores for each match decision. Streaming events and webhooks are supported. - name: Monitor description: >- The Monitor API watches the web for material changes on a fixed frequency. Each monitor runs once on creation and then on its configured schedule, emitting events when meaningful changes are detected. - `event_stream` monitors track a search query and emit an event for each new material change. - `snapshot` monitors track a specific task run's output and emit an event when the output changes. Results can be polled via the events endpoint or delivered via webhooks. - name: Chat API (Beta) description: >- The Chat API provides a programmatic chat-style text generation interface. It accepts a sequence of messages and returns model responses. Intended for assistant-like interactions and evaluation. Streaming responses are supported. paths: /v1beta/findall/runs/{findall_id}/cancel: post: tags: - FindAll summary: Cancel FindAll Run description: Cancel a FindAll run. operationId: cancel_findall_run_v1beta_findall_runs__findall_id__cancel_post parameters: - name: findall_id in: path required: true schema: type: string title: Findall Id - name: parallel-beta in: header required: false schema: anyOf: - type: string - type: 'null' title: Parallel-Beta x-stainless-override-schema: x-stainless-param: betas x-stainless-extend-default: true type: array description: Optional header to specify the beta version(s) to enable. items: $ref: '#/components/schemas/ParallelBeta' responses: '204': description: FindAll run cancelled successfully.
