Apex Endpoints and Regions

Hostname Pattern

Every Apex endpoint has one hostname that serves both transports:

Transport	Address	Protocol
HTTP (JSON-RPC and the plain HTTP routes)	`http://<code>.apex.orbitflare.com`	TCP port 80
QUIC	`<code>.apex.orbitflare.com:7001`	UDP port 7001

Replace <code> with a region code from the table below.

Regions

Region	Code	HTTP	QUIC
🇩🇪 Frankfurt, DE	`fra`	`http://fra.apex.orbitflare.com`	`fra.apex.orbitflare.com:7001`
🇳🇱 Amsterdam, NL	`ams`	`http://ams.apex.orbitflare.com`	`ams.apex.orbitflare.com:7001`
🇮🇪 Dublin, IE	`dub`	`http://dub.apex.orbitflare.com`	`dub.apex.orbitflare.com:7001`
🇬🇧 London, GB	`lon`	`http://lon.apex.orbitflare.com`	`lon.apex.orbitflare.com:7001`
🇺🇸 New York, US	`nyc`	`http://nyc.apex.orbitflare.com`	`nyc.apex.orbitflare.com:7001`
🇺🇸 Salt Lake City, US	`slc`	`http://slc.apex.orbitflare.com`	`slc.apex.orbitflare.com:7001`
🇸🇬 Singapore, SG	`sgp`	`http://sgp.apex.orbitflare.com`	`sgp.apex.orbitflare.com:7001`
🇯🇵 Tokyo, JP	`tyo`	`http://tyo.apex.orbitflare.com`	`tyo.apex.orbitflare.com:7001`
🇱🇹 Siauliai, LT	`sqq`	`http://sqq.apex.orbitflare.com`	`sqq.apex.orbitflare.com:7001`
🌐 Global (nearest)	`global`	`http://global.apex.orbitflare.com`	`global.apex.orbitflare.com:7001`

global.apex.orbitflare.com resolves to the healthy Apex endpoint nearest to you. The choice is made at DNS lookup, from your resolver’s view of your location: your own network when the resolver passes it on (Google and Quad9 do), otherwise the Cloudflare location your resolver reached. An endpoint that stops answering health checks leaves the answers within about a minute. A QUIC connection stays on the endpoint it resolved when it connected.

Choosing an Apex Endpoint

Pick the Apex endpoint nearest to the machine that sends the transaction. Every Apex endpoint knows the full leader schedule and routes each transaction to the validator clients nearest the upcoming leaders. Your choice affects your own round trip to the endpoint. It does not change the landing path. Use a named region rather than global when you need a fixed host, for example for a firewall rule or a pinned round trip. Measure before you decide. GET /ping needs no API key and returns pong:

for code in fra ams dub lon nyc slc sgp tyo sqq; do
  printf "%s " "$code"
  curl -s -o /dev/null -w "%{time_total}s\n" "http://$code.apex.orbitflare.com/ping"
done

The first request to each host includes the TCP handshake. Run the loop twice and compare the second pass, or see warm connections.

Firewall Rules

Direction	Protocol	Port	Used by
Outbound	TCP	80	JSON-RPC and plain HTTP routes
Outbound	UDP	7001	QUIC

The QUIC client binds an ephemeral local UDP port by default. If your firewall needs a fixed source port, the Rust client accepts a bind address through ClientOptions::bind_addr and the Go client through Options.BindAddr. See Rust client and Go client.

Utility Methods

These JSON-RPC methods work on every Apex endpoint without an API key:

Method	Returns
`getTipAccounts`	The tip accounts this Apex endpoint accepts
`getVersion`	The endpoint’s version
`health`	Whether the endpoint is up

curl -s http://fra.apex.orbitflare.com \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"getTipAccounts","params":[]}'
