Getting the Travis CI build status of a GitHub commit

Question

How would one get the build status of Travis CI of a particular GitHub commit from the of any arbitrary open source project?

Example

For example, how would an arbitrary GitHub user (with a Travis account) query the passing/failed build status of this build based on the following information:

• username: a-t-0
• repository: Code-LatexReportTemplate
• branch: main
• Commit: 2758dc700dfaa9726f0e1755753347b4d450acda

Attempts

To get the status of that commit I tried:

1. A get command:

GET /repos/a-t-0/Code-LatexReportTemplate/commits/2758dc700dfaa9726f0e1755753347b4d450acda/status

Which returns nothing.

2. A curl command:

curl \
  -H "Accept: application/vnd.github.v3+json" \
  https://api.github.com/repos/a-t-0/Code-LatexReportTemplate/commits/2758dc700dfaa9726f0e1755753347b4d450acda/status

Which returns a lot of information, but an empty statuses information as shown in the selected output below:

 "state": "pending",
  "statuses": [

  ],

This empty statuses information seems to be contradictory to the green checkflag on that commit, which shows the build on that commit is passed.

You can use the check-run api using Github API rest v3 like this

GET https://api.github.com/repos/[owner]/[repo]/commits/[hash]/check-runs

Example: https://api.github.com/repos/a-t-0/Code-LatexReportTemplate/commits/2758dc700dfaa9726f0e1755753347b4d450acda/check-runs

and for check-suites :

GET https://api.github.com/repos/[owner]/[repo]/commits/[hash]/check-suites

Example: https://api.github.com/repos/a-t-0/Code-LatexReportTemplate/commits/2758dc700dfaa9726f0e1755753347b4d450acda/check-suites

Using graphql API, you can use statusCheckRollup field :

query {
  repository(name: "Code-LatexReportTemplate", owner:"a-t-0"){
    object(oid: "2758dc700dfaa9726f0e1755753347b4d450acda") {
      ... on Commit {
        message
        statusCheckRollup {
          state
          contexts(first: 100) {
            nodes {
              __typename
              ... on CheckRun {
                name
                detailsUrl
                completedAt
                status
              }
            }
          }
        }
      }
    }
  }
}

which returns :

{
  "data": {
    "repository": {
      "object": {
        "message": "Removed another unneeded file.",
        "statusCheckRollup": {
          "state": "SUCCESS",
          "contexts": {
            "nodes": [
              {
                "__typename": "CheckRun",
                "name": "Travis CI - Branch",
                "detailsUrl": "https://travis-ci.com/github/a-t-0/Code-LatexReportTemplate/builds/211162054",
                "completedAt": "2020-12-29T13:12:26Z",
                "status": "COMPLETED"
              }
            ]
          }
        }
      }
    }
  }
}
