}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.SUB_USER_WALLET_TRANSACTION_DETECTED webhook to your server.
Example
const res = await fetch(`${BASE}/wallet/filter`, {
method: 'POST',
headers: makeHeaders(),
body: JSON.stringify({
address: '0xabc123...',
chains: ['ethereum', 'polygon'],
}),
});
const { data } = await res.json();
// data.watched → true
// data.chains → ['ethereum', 'polygon']
res = requests.post(
f"{BASE}/wallet/filter",
headers=make_headers(),
json={"address": "0xabc123...", "chains": ["ethereum", "polygon"]},
)
data = res.json()["data"]
