Create Namespace Api Key

Papr Memory API (1.0.0)

API for managing enterprise context and 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.

Create Namespace Api Key

Request

Mint a new API key bound to the given namespace. Caller must authenticate with any API key belonging to the same organization (typically the org-wide / default-namespace key).

Security: The full key is returned exactly once in this response. Store it immediately — it cannot be retrieved later. Subsequent reads expose only the masked key_prefix.

Path

Headers

X-API-Keystring(X-Api-Key)required

namestring(Name)[ 1 .. 128 ] charactersrequired

Human-readable name for the API key (shown in admin UIs).

Example: "Acme Production API Key"

environmentstring(Environment)

Environment label: development, staging, or production.

Default "production"

Enum"development""staging""production"

Example: "production"

permissionsArray of strings(Permissions)[ 1 .. 3 ] items

Transform text to graph embeddings

Request

Vector-store agnostic producer.

Returns everything you'd want to index in any vector DB -- base embedding, 14-band extracted signals, per-band SBERT/Qwen embeddings, phases, and optional rot_v3 / concat reconstructions.

Uses the SAME extraction + embedding path as /v1/graph/rerank uses for queries, so artifacts produced here can be scored by /v1/graph/rerank without any drift.

Bodyapplication/jsonrequired

textstring(Text)required

Source text to transform.

embeddingArray of Embedding (numbers) or Embedding (null)(Embedding)

Optional caller-provided base embedding (Qwen 2560-d). If omitted, the server computes it.

Any of:

Optional caller-provided base embedding (Qwen 2560-d). If omitted, the server computes it.

domain_idDomain Id (string) or Domain Id (null)(Domain Id)

Domain shortname or full schema id controlling which frequency bands and extraction rules are used. Built-in shortnames: "general" (default), "code", "cosqa", "codetrans", "codetransocean", "codetransocean_hybrid", "text2sql", "scifact", "nfcorpus", "fiqa", "legal", "medical", "ecommerce", "coffee_shops". You can also pass a full schema id (e.g. "code_search:cosqa:2.0.0") or a custom domain_id registered via POST /v1/graph/domains.

Any of:

string(Domain Id)

metadataMetadata (object) or Metadata (null)(Metadata)

Free-form user metadata to attach (optional, not used for scoring).

Any of:

Free-form user metadata to attach (optional, not used for scoring).

signal_embedderstring(Signal Embedder)

Embedder for per-band signal vectors. 'sbert' (384d, default) is ~10x cheaper to store than 'qwen' (2560d, matched to base).

Default "sbert"

Enum"sbert""qwen"

return_rot_v3boolean(Return Rot V3)

If true, include the rot_v3 vector in the response.

Default false

return_concatboolean(Return Concat)

If true, include the base + bands concatenation embedding.

Default false

curl -i -X POST \
