GET /v1/ping

A lightweight endpoint for keeping the underlying HTTPS connection alive between requests.

200 OK — empty body.

Why it exists

Section titled “Why it exists”

The server’s HTTP keepalive is configured to 70 seconds and 10 000 requests. If your client sits idle longer than 65 s, the connection is closed and the next request pays a full TCP + TLS handshake (~10–20 ms extra round-trip from Frankfurt).

Sending a ping every 60 seconds keeps the connection open and your first real request stays at baseline latency.

Manual implementation

Section titled “Manual implementation”
setInterval(async () => {
  await fetch("https://api.darkfibre.dev/v1/ping");
}, 60_000).unref();

Keep-alive only matters if your trading loop has gaps longer than ~60 s. For bots that trade continuously you can skip it.
