Response
Example response

The session windows of a trading date: stocks (pre_market 04:00, regular 09:30 to 16:00, after_hours until 20:00 Eastern), options (regular, overnight, curb) and futures (globex). Early-close days shorten regular and after-hours trading; weekends and market holidays have no sessions. Without asset every class is returned.

Example request

curl -sS "https://api.ordermap.si/v1/market/sessions" \
  -H "Authorization: Bearer $ORDERMAP_API_KEY"

const res = await fetch("https://api.ordermap.si/v1/market/sessions", {
  headers: { Authorization: `Bearer ${process.env.ORDERMAP_API_KEY}` },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data, meta } = await res.json();
console.log(data, meta.coverage);

Set ORDERMAP_API_KEY to your key. Replace the dates with a recent trading date.
