Endpoints & Regions

lucum.io operates endpoints across multiple regions. For best performance, send to the endpoint closest to your server's location.

TIP

We recommend sending to both your closest regional endpoint and one additional endpoint for redundancy.

WARNING

When using QUIC, we strongly recommend connecting via the raw IP address rather than the domain. This skips DNS resolution and reduces latency.

All Endpoints

Region	Endpoint	IP	Provider
Frankfurt	fra.lucum.io	64.130.40.195	Teraswitch
Frankfurt	fra2.lucum.io	84.32.98.249	Cherry Servers
Frankfurt	fra3.lucum.io	70.40.184.133	Allnodes
Amsterdam	ams.lucum.io	64.130.42.36	Teraswitch
Amsterdam	ams2.lucum.io	108.61.188.23	Vultr
New York	ny.lucum.io	206.223.233.127	Latitude
Tokyo	jp.lucum.io	198.13.42.17	Vultr
London	lon.lucum.io	64.34.86.109	Latitude

HTTP

Prefix the endpoint with http:// and pass your API key as a query parameter:

curl -X POST "http://fra.lucum.io/?api-key=YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "transaction": "BASE64_ENCODED_TX" }'

See Sending Transactions via HTTP for code examples.

QUIC

Connect directly to the endpoint or IP on port 8888:

fra.lucum.io:8888
64.130.40.195:8888

Using the raw IP is recommended for lowest latency as it skips DNS resolution.

See Sending Transactions via QUIC for code examples.

Tip Wallets

All transactions require a minimum tip of 0.001 SOL to one of:
