Memory API

Memory API is an HTTP interface an app calls to save facts about a person and to recall them later. Apps use it so their AI can answer with what it already knows about that user.

What Memory API is

A memory API is a set of web endpoints. The app sends text, a time, and a label to store it. Later, the app sends a query and gets back the stored items that match.

Each stored item is tied to one user, so one person's facts do not show up for another.

Why it matters

The AI does not need the whole history in each prompt.
Facts change over time, so the API needs a way to replace old values.
Recall has to respect time, so an answer can reflect what was true on a given date.

How it works in Harny

Harny's Memory API lives under /v1/memory. Your app calls POST /v1/memory/ingest to store facts and POST /v1/memory/recall to search them.
To remove data, call DELETE /v1/memory/data-points/{sourceId}. To check the month's count, call GET /v1/memory/usage.

Do end users need a Harny account?

No. The app's developer calls the Memory API on the app's behalf, and end users need no Harny account.
