Auth method: Signed (HMAC) — this endpoint requires the full set of signed headers: x-access-id, x-request-id, x-timestamp, and an HMAC-SHA256 authorization signature. See Authentication.

Example

const res = await fetch(`${BASE}/wallet/watch/0xabc123...`, {
  headers: makeHeaders(),
});

const { data } = await res.json();
// data.watched → true | false

res = requests.get(
    f"{BASE}/wallet/watch/0xabc123...",
    headers=make_headers(),
)
watched = res.json()["data"]["watched"]
