Papr Memory API (1.0.0)

API for managing memory, context, and retrieval for AI agents or apps 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.

Delete All Memories V1

Request

Delete all memory items for a user.

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

User Resolution:

If only API key is provided: deletes memories for the developer
If user_id or external_user_id is provided: resolves and deletes memories for that user
Uses the same user resolution logic as other endpoints

Required Headers:

X-Client-Type: (e.g., 'papr_plugin', 'browser_extension')

WARNING: This operation cannot be undone. All memories for the resolved user will be permanently deleted.

Search V1

Request

Search through memories with authentication required.

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

Custom Schema Support: This endpoint supports both system-defined and custom user-defined node types:

System nodes: Memory, Person, Company, Project, Task, Insight, Meeting, Opportunity, Code
Custom nodes: Defined by developers via UserGraphSchema (e.g., Developer, Product, Customer, Function)

When custom schema nodes are returned:

Each custom node includes a schema_id field referencing the UserGraphSchema
The response includes a schemas_used array listing all schema IDs used
Use GET /v1/schemas/{schema_id} to retrieve full schema definitions including:
- Node type definitions and properties
- Relationship type definitions and constraints
- Validation rules and requirements

Recommended Headers:

Accept-Encoding: gzip

The API supports response compression for improved performance. Responses larger than 1KB will be automatically compressed when this header is present.

HIGHLY RECOMMENDED SETTINGS FOR BEST RESULTS:

Set enable_agentic_graph: true for intelligent, context-aware search that can understand ambiguous references
Use max_memories: 15-20 for comprehensive memory coverage
Use max_nodes: 10-15 for comprehensive graph entity relationships

Agentic Graph Benefits: When enabled, the system can understand vague references by first identifying specific entities from your memory graph, then performing targeted searches. For example:

"customer feedback" → identifies your customers first, then finds their specific feedback
"project issues" → identifies your projects first, then finds related issues
"team meeting notes" → identifies your team members first, then finds meeting notes
"code functions" → identifies your functions first, then finds related code

Role-Based Memory Filtering: Filter memories by role and category using metadata fields:

metadata.role: Filter by "user" or "assistant"
metadata.category: Filter by category (user: preference, task, goal, facts, context | assistant: skills, learning)

User Resolution Precedence:

If both user_id and external_user_id are provided, user_id takes precedence.
If only external_user_id is provided, it will be resolved to the internal user.
If neither is provided, the authenticated user is used.

Query

max_memoriesinteger(Max Memories)[ 10 .. 50 ]

HIGHLY RECOMMENDED: Maximum number of memories to return. Use at least 15-20 for comprehensive results. Lower values (5-10) may miss relevant information. Default is 20 for optimal coverage.

Default 20

max_nodesinteger(Max Nodes)[ 10 .. 50 ]

HIGHLY RECOMMENDED: Maximum number of neo nodes to return. Use at least 10-15 for comprehensive graph results. Lower values may miss important entity relationships. Default is 15 for optimal coverage.

Default 15

Headers

Accept-Encodingstring

Recommended to use 'gzip' for response compression

Default gzip

Bodyapplication/jsonrequired

querystring(Query)required

Detailed search query describing what you're looking for. For best results, write 2-3 sentences that include specific details, context, and time frame. Examples: 'Find recurring customer complaints about API performance from the last month. Focus on issues where customers specifically mentioned timeout errors or slow response times in their conversations.' 'What are the main issues and blockers in my current projects? Focus on technical challenges and timeline impacts.' 'Find insights about team collaboration and communication patterns from recent meetings and discussions.'

Example: "Find recurring customer complaints about API performance from the last month. Focus on issues that multiple customers have mentioned and any specific feature requests or workflow improvements they've suggested."

rank_resultsboolean(Rank Results)

Whether to enable additional ranking of search results. Default is false because results are already ranked when using an LLM for search (recommended approach). Only enable this if you're not using an LLM in your search pipeline and need additional result ranking.

Default false

Example: true

enable_agentic_graphboolean(Enable Agentic Graph)

HIGHLY RECOMMENDED: Enable agentic graph search for intelligent, context-aware results. When enabled, the system can understand ambiguous references by first identifying specific entities from your memory graph, then performing targeted searches. Examples: 'customer feedback' → identifies your customers first, then finds their specific feedback; 'project issues' → identifies your projects first, then finds related issues; 'team meeting notes' → identifies team members first, then finds meeting notes. This provides much more relevant and comprehensive results. Set to false only if you need faster, simpler keyword-based search.

Default false

user_idUser Id (string) or User Id (null)(User Id)

Optional internal user ID to filter search results by a specific user. If not provided, results are not filtered by user. If both user_id and external_user_id are provided, user_id takes precedence.

Any of:

Optional internal user ID to filter search results by a specific user. If not provided, results are not filtered by user. If both user_id and external_user_id are provided, user_id takes precedence.

string(User Id)

Optional internal user ID to filter search results by a specific user. If not provided, results are not filtered by user. If both user_id and external_user_id are provided, user_id takes precedence.

external_user_idExternal User Id (string) or External User Id (null)(External User Id)

Optional external user ID to filter search results by a specific external user. If both user_id and external_user_id are provided, user_id takes precedence.

Example: "external_user_123"

Any of:

Optional external user ID to filter search results by a specific external user. If both user_id and external_user_id are provided, user_id takes precedence.

string(External User Id)

Optional external user ID to filter search results by a specific external user. If both user_id and external_user_id are provided, user_id takes precedence.

organization_idOrganization Id (string) or Organization Id (null)(Organization Id)

schema_idSchema Id (string) or Schema Id (null)(Schema Id)

Any of:

string(Schema Id)

simple_schema_modeboolean(Simple Schema Mode)

If true, uses simple schema mode: system schema + ONE most relevant user schema. This ensures better consistency between add/search operations and reduces query complexity. Recommended for production use.

Default false

metadataMemoryMetadata (object) or null

Optional metadata filter. Any field in MemoryMetadata (including custom fields) can be used for filtering.

Any of:

Optional metadata filter. Any field in MemoryMetadata (including custom fields) can be used for filtering.

search_overrideSearchOverrideSpecification (object) or null

OPTIONAL: Override automatic search query generation with your own exact graph pattern and filters. ⚡ AUTOMATIC BY DEFAULT: If not provided, the system automatically generates optimized Cypher queries using AI - no action required! 🎯 USE WHEN: You want precise control over search patterns, have specific graph traversals in mind, or want to bypass AI query generation for performance. 📋 VALIDATION: All patterns and filters must comply with your schema definitions.
