Timeseries

Some memories are about something that also has numbers over time. “Apple fell sharply after the earnings miss” is a text; Apple’s price around that date is a timeseries. gligabao stores both and links them, so the memory is tied to the data behind it. A series is not part of the graph. Its points live in tables of their own, and it is connected to the graph by anchors to an artifact, an entity or a fact (edge). This is the same split as for images. This page is the guide; every field, status code and table is in the Timeseries API reference.

Three ways to get a series

Way	When to use it	Where
Supply it with `remember`	You have the points when you remember the text	`timeseries.series` in `POST /v1/gb/remember`
Fetch it from a provider	You want gligabao to find series for the entities of the text	`timeseries.fetch` in `remember`, with providers your program registers
Supply it later	The entities are only known after `remember` returned, a series changes, or it is too big for `remember`	`POST /v1/gb/timeseries`

Nothing is fetched or derived by default: fetch and observations are opt-in because they cost time and LLM calls.

Supply a series with `remember`

{
  "user_id": "u1",
  "text": "Apple fell sharply after the earnings miss.",
  "kind": "episode",
  "reference_time": "2025-01-31T21:00:00Z",
  "timeseries": {
    "series": [{
      "key": "AAPL.close", "name": "Apple close", "unit": "USD",
      "points": [["2025-01-29T00:00:00Z", 235.1], ["2025-01-30T00:00:00Z", 237.6], ["2025-01-31T00:00:00Z", 222.0]],
      "anchors": [{"entity": {"name": "Apple", "type": "organization"}}]
    }]
  }
}

key identifies the series in the dataset. Sending the same key again adds points to it.
Points are [time, value] pairs: RFC 3339 times, finite numbers, any order.
The anchors say what the series is about. The entity does not exist when you make the request (it is what the extraction finds in the text), so you name it with a selector, {name, type}, and gligabao looks it up once the text has been stored. If the text never named Apple, the entity is created. A series with no anchors is anchored to the artifact of the request.

The response has a series item per series, with its id, the number of points, its stats and the anchors that were stored. See Anchors for artifacts, edges, IDs, role, window and on_unmatched.

Let gligabao fetch it

Register a provider when you start the server: a callback that fetches the data, and a description in plain language of when it applies. gligabao holds no provider logic of its own, so credentials, symbols and rate limits stay in your program.

gligabao.TimeseriesProvider{
    Name:        "prices",
    Description: "Daily close of stocks. Use for companies whose shares are publicly traded. Not for people, places or concepts.",
    QueryFormat: "the ticker symbol, e.g. AAPL",
    Fetch:       func(ctx context.Context, req gligabao.TimeseriesFetchRequest) ([]gligabao.TimeseriesData, error) { /* ... */ },
}

Then ask for it in a request:

{"user_id": "u1", "text": "Apple fell sharply after the earnings miss.", "kind": "episode", "reference_time": "2025-01-31T21:00:00Z",
 "timeseries": {"fetch": {"providers": ["prices"], "before": "30d", "after": "0"}}}

After the text is stored, an LLM reads the descriptions of the providers and the entities of the text, and decides which provider fetches which entity (Apple to AAPL). It prefers to skip an entity it is not sure of. The series is then stored and anchored to the entity and to the artifact it came from.

The period is 30 days before the reference_time and nothing after by default, so a memory never contains the future of its event. Set after if you want an event window.
A failure while fetching never fails remember; it is reported in the response.
Write the Description carefully: the whole decision rests on it.

The full provider contract (Name, Description, QueryFormat, Fetch, validation, limits) is in Providers.

Stats

Whenever points are written, gligabao computes a summary of all the points of the series, in Go (an LLM never does): count, first and last value, min, max, mean, change, percent change, trend (up, down or flat) and the largest_move between two consecutive points. It is returned with the series and stored with it. See Stats.

Turn a series into facts

A series is not in the graph, so by default query does not see it. With timeseries.observations: true, remember writes a short text from the stats of each series it stored, and runs it through the normal pipeline. The text is generated by Go from the numbers, so it only says what they say:

Apple close fell 5.57% in this period, from 235.1 USD on 2025-01-29 to 222 USD on 2025-01-31.

Its facts reach the graph like any fact (bi-temporal, deduplicated, embedded), and the stored series_observation artifact links them back to the series. Observations are opt-in, at most 10 per request. See Observations.

Read a series back

GET /v1/gb/timeseries lists the dataset’s series, without points.
GET /v1/gb/timeseries/{id} returns one series with its points, between optional from and to.

See Reading.

Things to know

A supplied series is never clipped. If it runs past the reference_time, the memory contains the future of the event. Clip it before sending if that matters. Fetched series are clipped to their period.
query does not use series yet, and series are not embedded.
A series has at most 100,000 points per request; send more in several requests.
Times are UTC, and unit and frequency are labels.

The rest is in Limitations. The reasoning behind the design is in the Timeseries design proposal.
