# MemoryLake API Reference

> Complete API documentation for MemoryLake — turn documents and conversations into searchable, structured memories

## 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.

## Base URL

```
https://app.memorylake.ai/openapi/memorylake
```

## Authentication

All API requests require a Bearer token in the `Authorization` header. See [Authentication](/features/memorylake/api-reference/authentication) for details.

## Common Patterns

### Response Format

All responses follow this structure:

```json theme={null}
{
  "success": true,
  "message": "Operation completed successfully",
  "data": {
    // Response payload
  }
}
```

Error responses:

```json theme={null}
{
  "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
```
