POST /faucet

Claim testnet faucet

Claim testnet faucet.

operationId: claimFaucet

Not reachable through CCXT. Testnet-only token dispenser. Not a venue capability CCXT models at all.

Authentication: hmacAuth.

Credit a fixed testnet faucet amount of synthetic USDX to the authenticated account, subject to a per-wallet cooldown and cumulative cap.

Testnet only. There is no faucet on mainnet — real-funds collateral arrives through the USDX bridge instead. Do not build a funding flow that assumes this operation exists on every network.

Example

cURL

curl -X POST 'https://exchange.nexus.xyz/api/exchange/faucet' \
  -H 'X-API-Key: nx_7f3a1b...' \
  -H 'X-Timestamp: 1776033911836' \
  -H 'X-Signature: <hmac-sha256>'

Python

import requests

headers = {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
}

response = requests.post("https://exchange.nexus.xyz/api/exchange/faucet", headers=headers)
response.raise_for_status()
print(response.json())

TypeScript

const response = await fetch("https://exchange.nexus.xyz/api/exchange/faucet", {
  method: "POST",
  headers: {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
  },
});
if (!response.ok) throw new Error(`${response.status} ${await response.text()}`);
console.log(await response.json());

X-Signature is a placeholder: it is derived from this specific request. See Authentication for the canonical string and the HMAC rule.
