Validator Client API: Authorization Header
Overview
The validator client HTTP server requires that all requests have the following HTTP header:
- Name:
Authorization - Value:
Bearer <api-token>
Where <api-token> is a string that can be obtained from the validator client
host. Here is an example of the Authorization header:
Authorization: Bearer hGut6B8uEujufDXSmZsT0thnxvdvKFBvh
Obtaining the API token
The API token is stored as a file in the validators directory. For most users
this is ~/.lighthouse/{network}/validators/api-token.txt, unless overridden using the
--http-token-path CLI parameter. Here's an
example using the cat command to print the token for mainnet to the terminal, but any
text editor will suffice:
cat ~/.lighthouse/mainnet/validators/api-token.txt
hGut6B8uEujufDXSmZsT0thnxvdvKFBvh
When starting the validator client it will output a log message containing the path to the file containing the api token.
Sep 28 19:17:52.615 INFO HTTP API started api_token_file: "$HOME/hoodi/validators/api-token.txt", listen_address: 127.0.0.1:5062
The path to the API token may also be fetched from the HTTP API itself (this endpoint is the only one accessible without the token):
curl http://localhost:5062/lighthouse/auth
Response:
{
"token_path": "/home/karlm/.lighthouse/hoodi/validators/api-token.txt"
}
Example
Here is an example curl command using the API token in the Authorization header:
curl localhost:5062/lighthouse/version -H "Authorization: Bearer hGut6B8uEujufDXSmZsT0thnxvdvKFBvh"
The server should respond with its version:
{"data":{"version":"Lighthouse/v0.2.11-fc0654fbe+/x86_64-linux"}}
