Update Memory V1

Papr Memory API (1.0.0)

API for managing personal memory items with authentication and user-specific data.

Authentication

This API supports three authentication methods:

API Key: Include your API key in the X-API-Key header
```
X-API-Key: <your-api-key>
```
Session Token: Include your session token in the X-Session-Token header
```
X-Session-Token: <your-session-token>
```
Bearer Token: Include your OAuth2 token from Auth0 in the Authorization header
```
Authorization: Bearer <token>
```

All endpoints require one of these authentication methods.

Operations

Add Memory V1

Request

Add a new memory item to the system with size validation and background processing.

Authentication Required: One of the following authentication methods must be used:

Bearer token in Authorization header
API Key in X-API-Key header
Session token in X-Session-Token header

Required Headers:

Content-Type: application/json
X-Client-Type: (e.g., 'papr_plugin', 'browser_extension')

Role-Based Memory Categories:

User memories: preference, task, goal, facts, context
Assistant memories: skills, learning

New Metadata Fields:

metadata.role: Optional field to specify who generated the memory (user or assistant)
metadata.category: Optional field for memory categorization based on role
Both fields are stored within metadata at the same level as topics, location, etc.

The API validates content size against MAX_CONTENT_LENGTH environment variable (defaults to 15000 bytes).

Query

skip_background_processingboolean(Skip Background Processing)

If True, skips adding background tasks for processing

Default false

enable_holographicboolean(Enable Holographic)

If True, applies holographic neural transforms and stores in holographic collection

Default false

formatFormat (string) or Format (null)(Format)

Response format. Use 'omo' for Open Memory Object standard format (portable across platforms).

memory_policyMemoryPolicy (object) or null

Unified policy for graph generation and OMO safety. Use mode='auto' (LLM extraction, constraints applied if provided) or 'manual' (exact nodes). Includes consent, risk, and ACL settings. If schema_id is set, schema's memory_policy is used as defaults.

Any of:

link_toLink To (string) or Array of Link To (strings) or Link To (object) or Link To (null)(Link To)

Shorthand DSL for node/edge constraints. Expands to memory_policy.node_constraints and edge_constraints. Formats: - String: 'Task:title' (semantic match on Task.title) - List: ['Task:title', 'Person:email'] (multiple constraints) - Dict: {'Task:title': {'set': {...}}} (with options) Syntax: - Node: 'Type:property', 'Type:prop=value' (exact), 'Type:prop~value' (semantic) - Edge: 'Source->EDGE->Target:property' (arrow syntax) - Via: 'Type.via(EDGE->Target:prop)' (relationship traversal) - Special: '$this', '$previous', '$context:N' Example: 'SecurityBehavior->MITIGATES->TacticDef:name' with {'create': 'never'}

Any of:

string(Link To)

contentstring(Content)required
