# HTTP API
|
|
|
|
[OpenAPI Specification](https://ethereum.github.io/beacon-APIs/)
|
|
|
|
## 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](https://github.com/ethereum/beacon-APIs).
|
|
It is an easy-to-use RESTful HTTP/JSON API. An interactive specification is
|
|
available [here](https://ethereum.github.io/beacon-APIs/).
|
|
|
|
## 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"
|
|
|
