}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. See
Subwallets for the payload.
Example
const res = await fetch(`${BASE}/wallet/filter`, {
method: 'POST',
headers: makeHeaders(),
body: JSON.stringify({
address: '0x1a2b3c...',
chains: ['EVM'],
}),
});
const { data } = await res.json();
// data.watched → true
// data.chains → ['BTC', 'EVM', 'TRON']
res = requests.post(
f"{BASE}/wallet/filter",
headers=make_headers(),
json={"address": "0x1a2b3c...", "chains": ["EVM"]},
)
data = res.json()["data"]

Authorizations
Signed (HMAC) authentication. Required headers: x-access-id, x-request-id (UUID v4), x-timestamp (ISO 8601, must be within 5 minutes of server time), and authorization: the Base64 HMAC-SHA256 of the JSON string {"timeStamp":"","requestId":"","accessId":""} (keys in that order, no whitespace) using your access secret. The request body, method and path are not signed. The API key must be linked to an outlet.
