List complete MSF revisions after a scope-bound cursor.

GET

/v1/leagues/{league}/{dataset}/changes

const url = 'https://api.betflux.ai/v1/leagues/example/example/changes?cursor=example';
const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};

try {
  const response = await fetch(url, options);
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error(error);
}

curl --request GET \
  --url 'https://api.betflux.ai/v1/leagues/example/example/changes?cursor=example' \
  --header 'Authorization: Bearer <token>'

Pages stop at revision boundaries. Send the first page’s high_water_revision as until_revision on every later page to hold that high-water mark fixed. For a key whose history window ends before the head (the demo key’s sample month), high_water_revision is the last revision that key may read. A cursor for another dataset or scope is a 400. Served only where MSF serving is enabled: GET /v1/datasets lists the MSF datasets available, and elsewhere every MSF route answers 404.
