Sync

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.

Get Sync Tiers

Request

Return initial Tier 0 (goals/OKRs/use-cases --> tier 0 memories) and Tier 1 (hot memories) for the requesting user/workspace.

This is a minimal initial implementation to enable SDK integration. It uses simple heuristics and will be enhanced with analytics-driven selection.

Bodyapplication/jsonrequired
max_tier0integer(Max Tier0)[ 0 .. 2000 ]

Max Tier 0 items (goals/OKRs/use-cases)

Default 300
Example: 300
max_tier1integer(Max Tier1)[ 0 .. 5000 ]

Max Tier 1 items (hot memories)

Default 1000
Example: 1000

Any of:

Optional workspace id to scope tiers

string(Workspace Id)

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

Optional internal user ID to filter tiers 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.

Example: "internal_user_123"
Any of:

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

Example: "external_user_abc"
Any of:

Optional external user ID to filter tiers 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 tiers 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)

Optional organization ID for multi-tenant scoping. When provided, tiers are scoped to memories within this organization.

Any of:

Optional organization ID for multi-tenant scoping. When provided, tiers are scoped to memories within this organization.

string(Organization Id)

Optional organization ID for multi-tenant scoping. When provided, tiers are scoped to memories within this organization.

namespace_idNamespace Id (string) or Namespace Id (null)(Namespace Id)

Optional namespace ID for multi-tenant scoping. When provided, tiers are scoped to memories within this namespace.

Any of:

Optional namespace ID for multi-tenant scoping. When provided, tiers are scoped to memories within this namespace.

string(Namespace Id)

Optional namespace ID for multi-tenant scoping. When provided, tiers are scoped to memories within this namespace.

include_embeddingsboolean(Include Embeddings)

Default false
embedding_formatstring(EmbeddingFormat)

Embedding format: 'int8' (quantized, 4x smaller, default for efficiency), 'float32' (full precision, recommended for CoreML/ANE fp16 models). Only applies to Tier1; Tier0 always uses float32 when embeddings are included.

Default "int8"
Enum"int8""float32"
embed_modelstring(Embed Model)

Embedding model hint: 'sbert' or 'bigbird' or 'Qwen4B'

Default "Qwen4B"
Example: "sbert"
