Built by Metorial, the integration platform for agentic AI.
Generate text from a single prompt using Writer's Palmyra models. Unlike chat completion, this takes a plain text prompt and returns a text continuation. Best for single-turn text generation tasks like summarization, rewriting, or content creation.
Download the content of a file by its ID. Returns the file content as text.
Permanently delete a file from Writer. The file will be disassociated from all Knowledge Graphs. This action cannot be undone.
Retrieve details of a specific no-code agent (application) including its required inputs, configuration, and capabilities. Use this to understand what inputs are needed before invoking an agent.
List files uploaded to Writer. Returns file metadata including ID, name, status, and associated Knowledge Graph IDs. Supports pagination and ordering.
Add an uploaded file to a Knowledge Graph. The file must be uploaded to Writer first using the file upload process. Once added, the file's content becomes queryable through the Knowledge Graph.
Ask a question to one or more Knowledge Graphs and get an AI-generated answer grounded in your uploaded data. Returns the answer, source references, and optional inline citations. Supports subquery decomposition for complex questions.
Run a deployed no-code agent (application) as a microservice by providing its required inputs. Returns the generated output. Use **List Agents** first to find the agent ID and required input fields.
Retrieve details of a specific Knowledge Graph by its ID, including its name, description, and creation date.
List all Knowledge Graphs in your Writer account. Returns the ID, name, description, and creation date of each graph.
Create a new Knowledge Graph in Writer. A Knowledge Graph is a collection of files used for RAG-based question answering. After creation, add files to it using the **Manage Knowledge Graph Files** tool.
Generate AI responses from conversation history using Writer's Palmyra models. Supports multi-turn conversations with system, user, and assistant messages. Can leverage **tool calling** with custom functions, Knowledge Graph queries, and web search. Use **response format** to get structured JSON output (palmyra-x4 and palmyra-x5).
List deployed no-code agents (applications) in your Writer account. Returns agent metadata including IDs, names, and types. Use this to discover available agents and their application IDs before invoking them.
List all available Palmyra models in your Writer account. Returns model IDs, names, and types. Use this to discover which models are available for text generation and chat completions.
Permanently delete a Knowledge Graph and disassociate all its files. This action cannot be undone.
Remove a file from a Knowledge Graph. The file itself is not deleted and can be re-added later or used with other graphs.
Update the name and/or description of an existing Knowledge Graph.
Retrieve metadata for a specific file by its ID, including the file name, processing status, and associated Knowledge Graphs.
