# /s requests

[As described above](https://code.tag.bio/v1/docs/fc-api-methods-high-level), the /s API method requests metadata about the FC.

## Request

It requires no JSON payload.

## Response

The response to the `/s` request is also quite useful for encoding provenance on analysis results and other [Useful Data ArtifacTs (UDATs)](https://medium.com/tag-bio/a-brief-introduction-to-useful-data-artifacts-and-the-next-generation-of-data-analysis-systems-1f42ef91ce92). For UDATs to be fully reproducible, they must be calculated from the exact same data, and with the exact same server configuration (FC version, FC project repository version).

## Example /s response

```
{
  "version": "2.88.95", // <-- FC server version
  "commit": "N/A", // <-- The git commit for fc-iris when the server was started
  "start_time": "1677024487695",
  "data_commit": "N/A", // <-- The git commit for fc-iris when the data model was created

  "data_version": "af894ab0-6c1c-4153-8a1d-19b9bcd326fe", // <-- Data model UUID
