HTTP API
Beacon Node
A Lighthouse beacon node can be configured to expose a HTTP server by supplying the --http
flag. The default listen address is localhost:5052
.
The following CLI flags control the HTTP server:
--http
: enable the HTTP server (required even if the following flags are provided).--http-port
: specify the listen port of the server.--http-address
: specify the listen address of the server.
The schema of the API aligns with the standard Eth2 Beacon Node API as defined at github.com/ethereum/beacon-APIs. It is an easy-to-use RESTful HTTP/JSON API. An interactive specification is available here.
Troubleshooting
HTTP API is unavailable or refusing connections
Ensure the --http
flag has been supplied at the CLI.
You can quickly check that the HTTP endpoint is up using curl
:
curl "localhost:5052/beacon/head"
