Overview - EDN

The EDN Memory API is a REST API that gives your AI app persistent memory. Your app saves conversation turns to EDN, then asks EDN for the relevant memory before each model call, as a SIP.

New to EDN? The Quickstart takes you from an API key to your first SIP in a few minutes.

Base URL and authentication

All endpoints sit under one base URL, and every request sends your API key as a bearer token:

curl https://api.tensorpro.ai/api/v1/memory/records \
  -H "Authorization: Bearer YOUR_API_KEY"

Setting	Value
Base URL	`https://api.tensorpro.ai/api/v1` (private beta)
Auth header	`Authorization: Bearer YOUR_API_KEY`
API keys	Create them in the Console. See Authentication
No key needed	Health check only

Endpoints

Save memory

Save conversation turns and selected assistant outputs as memory.

Manage memory

List, read, edit and delete memories, and see their history.

Retrieve

Build a SIP for your model, or search memory.

Documents

Upload documents for EDN to answer from.

Projects

Group documents and memory into separate project scopes.

Sessions

Manage conversations and store their transcripts.

Conventions

Format: request and response bodies are JSON. Document upload is the exception: it sends the file as a form upload (multipart/form-data).
IDs: EDN generates the IDs of memories, projects and project documents.
Session IDs: you choose session_id yourself.
- Reuse it for every request in the same conversation. EDN creates the session the first time you use a new ID.
- It must be 1 to 128 characters long.
- It can contain letters, digits and these symbols: period (.), underscore (_), colon (:) and hyphen (-).
Timestamps: ISO 8601 strings in UTC, such as 2026-11-10T04:43:25+00:00.
Empty values: optional response fields may be null when no value is available.

Pagination

List endpoints use limit and offset. If you request a limit above the endpoint’s maximum, EDN returns the maximum allowed number of results.

Endpoint	Default `limit`	Maximum
List memories	50	200
List sessions	50	200
List session messages	50	200
Search memories	10	50

Listing projects and project documents returns every item.

Errors and rate limits

Topic	What to know
Errors	Every error returns `{"detail": "...", "code": "..."}`. Each endpoint page lists the errors it can return. See Error handling
Usage limits	During the beta, each account has a per-minute request limit and a daily limit on saving memory and on building SIPs. Limits may change as the beta develops
Over a limit	EDN returns `429` with a `Retry-After` header telling the client how many seconds to wait

Versioning

The API version is part of the path: /api/v1. The API is currently in private beta, and breaking changes are announced to beta testers before they ship.
