# Mercury CLI – Run your banking* from the terminal

The official command-line interface for Mercury.

Manage your Mercury account from the terminal — cards, transactions, accounts, and more.

## Install

### curl

```sh
curl -sSf https://cli.mercury.com/install.sh | sh
```

### Nix

Run without installing:

```sh
nix run github:MercuryTechnologies/mercury-cli -- accounts list
```

Install into your profile:

```sh
nix profile install github:MercuryTechnologies/mercury-cli
```

Use as a Nixpkgs overlay:

```nix
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    mercury-cli.url = "github:MercuryTechnologies/mercury-cli";
  };

  outputs = { nixpkgs, mercury-cli, ... }: {
    nixosConfigurations.example = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ({ pkgs, ... }: {
          nixpkgs.overlays = [ mercury-cli.overlays.default ];
          environment.systemPackages = [ pkgs.mercury-cli ];
        })
      ];
    };
  };
}
```

Requires [Nix](https://nixos.org/download) (or [Lix](https://lix.systems/install/)) with flakes enabled.

### Install with Go

To test or install the CLI locally, you need [Go](https://go.dev/doc/install) version 1.22 or later installed.

<!-- x-release-please-start-version -->

```sh
go install 'github.com/MercuryTechnologies/mercury-cli/cmd/mercury@latest'
```

<!-- x-release-please-end -->

Once you have run `go install`, the binary is placed in your Go bin directory:

- **Default location**: `$HOME/go/bin` (or `$GOPATH/bin` if GOPATH is set)
- **Check your path**: Run `go env GOPATH` to see the base directory

If commands aren't found after installation, add the Go bin directory to your PATH:

```sh
# Add to your shell profile (.zshrc, .bashrc, etc.)
export PATH="$PATH:$(go env GOPATH)/bin"
```

## Quick start

```sh
mercury login
mercury accounts list
mercury payments create \
  --account-id acc_xxx \
  --recipient-id rcp_xxx \
  --amount 5000 \
  --payment-method ach \
  --idempotency-key $(uuidgen)
```

## What you can do

- View accounts and balances (`mercury accounts`)
- Send payments and transfer funds between accounts (`mercury payments`)
- List, search, and update transactions (`mercury transactions`)
- Manage cards (`mercury cards`)
- Manage recipients, customers, and invoices (`mercury recipients`, `mercury customers`, `mercury invoices`)
- Download statements and SAFE documents (`mercury statements`, `mercury safes`)
- Manage treasury accounts (`mercury treasury`)
- Create and verify webhook endpoints (`mercury webhooks`)

## Upgrading

```sh
mercury upgrade                  # latest
mercury upgrade --version 0.3.1  # pin a version
mercury upgrade --force          # reinstall current
```

Set `MERCURY_INSTALL_DIR` to override the install location.

When a newer release is available, `mercury` prints a one-line notice on stderr
after the command runs (at most once per day). To disable it:

```sh
export MERCURY_NO_UPDATE_CHECK=1
```

### Running Locally

After cloning the git repository for this project, you can use the
`scripts/run` script to run the tool locally:

```sh
./scripts/run args...
```

## Usage

The CLI follows a resource-based command structure:

```sh
mercury [resource] <command> [flags...]
```

```sh
mercury accounts get \
  --api-key 'My API Key' \
  --account-id REPLACE_ME
```

For details about specific commands, use the `--help` flag.

### Environment variables

| Environment variable | Description                                  |
| -------------------- | -------------------------------------------- |
| `MERCURY_API_KEY`    | Bearer token authentication for Mercury API. |

Create and manage API tokens here: https://app.mercury.com/settings/tokens

Your Mercury API token should include the `secret-token:` prefix. Use it in the
`Authorization` header:

```
Authorization: Bearer secret-token:mercury_<TOKEN>
```

If `--api-key` or `MERCURY_API_KEY` is set, the API token takes precedence over
any OAuth session from `mercury login`. Run `mercury status` to see
which credential is active.

### Global flags

- `--api-key` - Bearer token for Mercury API
- `--help` - Show command line usage
- `--debug` - Enable debug logging (includes HTTP request/response details)
- `--version`, `-v` - Show the CLI version
- `--base-url` - Use a custom API backend URL
- `--format` - Change the output format (`auto`, `explore`, `json`, `jsonl`, `pretty`, `raw`, `yaml`)
- `--format-error` - Change the output format for errors (`auto`, `explore`, `json`, `jsonl`, `pretty`, `raw`, `yaml`)
- `--transform` - Transform the data output using [GJSON syntax](https://github.com/tidwall/gjson/blob/master/SYNTAX.md)
- `--transform-error` - Transform the error output using [GJSON syntax](https://github.com/tidwall/gjson/blob/master/SYNTAX.md)

### Filling out `mercury apply`

To start a Mercury application, write out a blank annotated template, fill it
in, and submit it via stdin:

```bash
mercury apply --template > apply.yaml   # write a blank template
# edit apply.yaml with your details
mercury apply < apply.yaml              # submit
```

Explicit flags still override values from the piped file.

### Passing files as arguments

To pass files to your API, you can use the `@myfile.ext` syntax:

```bash
mercury <command> --arg @abe.jpg
```

Files can also be passed inside JSON or YAML blobs:

```bash
mercury <command> --arg '{image: "@abe.jpg"}'
# Equivalent:
mercury <command> <<YAML
arg:
  image: "@abe.jpg"
YAML
```

If you need to pass a string literal that begins with an `@` sign, you can
escape the `@` sign to avoid accidentally passing a file.

```bash
mercury <command> --username '\@abe'
```

#### Explicit encoding

For JSON endpoints, the CLI tool does filetype sniffing to determine whether the
file contents should be sent as a string literal (for plain text files) or as a
base64-encoded string literal (for binary files). If you need to explicitly send
the file as either plain text or base64-encoded data, you can use
`@file://myfile.txt` (for string encoding) or `@data://myfile.dat` (for
base64-encoding). Note that absolute paths will begin with `@file://` or
`@data://`, followed by a third `/` (for example, `@file:///tmp/file.txt`).

```bash
mercury <command> --arg @data://file.txt
```
