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/validate`, {
  method: 'POST',
  headers: makeHeaders(),
  body: JSON.stringify({
    address:  '0xabc123...',
    networks: ['ethereum'],
  }),
});

const { data } = await res.json();
// data.valid → true

res = requests.post(
    f"{BASE}/wallet/validate",
    headers=make_headers(),
    json={"address": "0xabc123...", "networks": ["ethereum"]},
)
valid = res.json()["data"]["valid"]
