MemoryLake API Reference

API Overview

The MemoryLake API lets you feed documents and conversations into a project, automatically extract structured facts, and search across all memory sources with natural language. Use it to build AI applications with long-term memory.

Authentication

All API requests require a Bearer token in the Authorization header. See Authentication for details.

API Sections

Core Memory Operations

The 3 essential APIs: import documents, append conversation messages, and search memories.

Library

File storage — upload and manage files before importing them into projects.

Workspaces

Create and manage workspaces — the top-level namespace for data isolation.

Actors

Manage participant identities and their associated facts.

Agents

Define AI agents with versioning and A2A protocol support.

Projects

Manage projects and their documents, conversations, and facts.

Common Patterns

Response Format

All responses follow this structure:

{
  "success": true,
  "message": "Operation completed successfully",
  "data": {
    // Response payload
  }
}

Error responses:

{
  "success": false,
  "message": "Error description",
  "error_code": "ERROR_CODE"
}

Pagination

List endpoints use continuation-token pagination: Query Parameters:

page_size: Number of items per page
continuation_token: Token from a previous response to fetch the next page

When the response continuation_token is null, there are no more pages.

Timestamps

All timestamps use ISO 8601 format:

2024-01-15T10:30:00Z
