How to request it

When this dataset appears in your account’s catalog, select its version, supported fields and exact entity identifiers. Set a short date range and an as_of time, then request a small page. The record key identifies a row; it is not necessarily the identifier accepted by the query filter.

HTTP request template

This is a template, not a currently available request. Fill each variable from the authenticated catalog and your intended query. The Explorer can generate a complete request for an available dataset.

GET /v1/data/etf.master.aliasesHTTP

curl --fail-with-body --get "$ORIGINFOLD_API_URL/v1/data/etf.master.aliases" \
  --header "Authorization: Bearer $ORIGINFOLD_API_KEY" \
  --data-urlencode "dataset_version=$DATASET_VERSION" \
  --data-urlencode "fields=$FIELDS" \
  --data-urlencode "entity_id=$ENTITY_ID" \
  --data-urlencode "start=$START_DATE" \
  --data-urlencode "end=$END_DATE" \
  --data-urlencode "as_of=$AS_OF" \
  --data-urlencode "limit=25"
