description: |
operator api is a utility command for accessing Nomad's HTTP API similar to
the popular open source program curl.
---
# Command: operator api
The `operator api` command allows easy access to Nomad's HTTP API similar to
the popular [curl] program. Nomad's `operator api` command reads [environment
variables][envvars] to dramatically ease HTTP API access compared to trying to
manually write the same command with the third party `curl` command.
For example for the following environment:
```
NOMAD_TOKEN=d4434353-c797-19e4-a14d-4068241f86a4
NOMAD_CACERT=$HOME/.nomad/ca.pem
NOMAD_CLIENT_CERT=$HOME/.nomad/cli.pem
NOMAD_CLIENT_KEY=$HOME/.nomad/client-key.pem
NOMAD_TLS_SERVER_NAME=client.global.nomad
NOMAD_ADDR=https://remote.client123.internal:4646
```
Accessing Nomad's [`/v1/jobs`][jobs] HTTP endpoint with `nomad operator
api` would require:
```
nomad operator api /v1/jobs
```
Performing the same request using the external `curl` tool would require:
```
curl \
--cacert "$HOME/.nomad/ca.pem" \
--cert "$HOME/.nomad/client.pem" \
--key "$HOME/.nomad/client-key.pem" \
--connect-to "client.global.nomad:4646:remote.client123.internal:4646" \
-H "X-Nomad-Token: ${NOMAD_TOKEN}" \
https://client.global.nomad:4646/v1/jobs
```
## General Options
@include 'general_options.mdx'
## Operator API Options
- `-dryrun`: output a curl command instead of performing the HTTP request
immediately. Note that you do *not* need the 3rd party `curl` command
installed to use `operator api`. The `curl` output from `-dryrun` is intended
for use in scripts or running in locations without a Nomad binary present.
- `-filter`: Specifies an expression used to filter query results.
- `-H`: Adds an additional HTTP header to the request. May be specified more
than once. These headers take precedence over automatically set ones such as
X-Nomad-Token.
- `-verbose`: Output extra information to stderr similar to curl's --verbose
flag.
- `-X`: HTTP method of request. If there is data piped to stdin, then the
method defaults to POST. Otherwise the method defaults to GET.
## Examples
```shell-session
$ nomad operator api -verbose /v1/agent/members?pretty
> GET http://127.0.0.1:4646/v1/agent/members?pretty=
