TonikAPI

Query, transform, and extract features from multidimensional data stores

Overview

TonikAPI is designed for efficient retrieval, transformation, and feature extraction of time-series and spectrogram-like data stored in hierarchical formats. It supports subdirectory traversal, resampling, log-scaling, and normalization.

This API is especially suited for applications in seismology, geophysics, and related fields.

Endpoints

Endpoint Method Description
/feature GET Returns time series or spectrogram features for a given group, variable, and time range.
/inventory GET Lists available datasets or subdirectories within a group.
/labels GET Fetches labels associated with a dataset for a specified time range.

Feature Request Example

Example query for retrieving a feature:

GET /feature?group=testgroup&name=rms&starttime=2023-01-01T00:00:00&endtime=2023-01-02T00:00:00&resolution=1h&log=true&normalise=true

Try Feature Query

curl "http://localhost:8003/feature?group=testgroup&name=rms&starttime=2023-01-01T00:00:00&endtime=2023-01-02T00:00:00&resolution=1h&log=true&normalise=true"

Inventory and Labels

Query inventory of datasets:

GET /inventory?group=testgroup

Query labels for a dataset:

GET /labels?group=testgroup&starttime=2023-01-01T00:00:00&endtime=2023-01-02T00:00:00

Python Example

You can query the TonikAPI directly from Python using requests:

import requests

params = {
    "group": "testgroup",
    "name": "rms",
    "starttime": "2023-01-01T00:00:00",
    "endtime": "2023-01-02T00:00:00",
    "resolution": "1h",
    "log": "true",
    "normalise": "true"
}

response = requests.get("http://localhost:8003/feature", params=params)
with open("rms_feature.csv", "w") as f:
    f.write(response.text)
