Authentication - Marks Hedging API

Every request authenticates with your API key, sent as a Bearer token:

Authorization: Bearer mk_live_xxxxxxxx

Create and manage keys in Settings on the partner desk. The full key is shown only once at creation and cannot be retrieved later, so save it somewhere secure and keep it secret. A request without a valid key returns 401.

Environments

Your key prefix selects the environment:

mk_live_ - production
mk_test_ - sandbox

The prefix is authoritative: a mk_test_ key always runs against the sandbox, so a test call can never reach production by accident. The same endpoints serve both; only the key differs.

Your first request

curl https://api.marks.finance/api/v2/partners/account \
  -H "Authorization: Bearer mk_test_xxxxxxxx"

import requests

r = requests.get(
    "https://api.marks.finance/api/v2/partners/account",
    headers={"Authorization": "Bearer mk_test_xxxxxxxx"},
)
print(r.json()["data"])

const r = await fetch("https://api.marks.finance/api/v2/partners/account", {
  headers: { Authorization: "Bearer mk_test_xxxxxxxx" },
});
const { data } = await r.json();
console.log(data);
