# 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 Ethereum 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"
