# Services & authentication { #services-auth }

## `services`

- **Type:** `dict` keyed by service tag  ·  **Default:** `{}`

Per-service configuration, keyed by the canonical service tag (for example `EXAMPLE1`, `EXAMPLE2`,
`EXAMPLE3`). unshackle reads several well-known sub-keys out of each service's block:

- **`proxy_map`**: remaps the region query you passed to `-p/--proxy` for this service.
  A config key is that query, or `"provider:query"` when the flag also named a proxy provider. The value is
  the query asked of the proxy provider instead. It has no effect when you give `-p` a full proxy URL.
- **`title_map`**: an exact-match rename map applied to fetched titles (source name →
  desired name), so a service that names a title differently from your library still matches.
- **`dl`**: per-service download defaults, using the same keys as the global
  [`dl`](download.md#dl) block.

Individual services may read any additional keys they define. unshackle hands the merged result
(the service's own `config.yaml` with this block layered on top) to the service as `self.config`.

User- or device-specific values (API keys, account IDs, device attributes) belong in this block
rather than in the service's own `config.yaml`, which holds shared defaults. See
[creating a service](../../dev/creating-a-service.md).

```yaml
services:
  EXAMPLE1:
    proxy_map:
      us: us-nyc
      "nordvpn:ca": ca-toronto
    title_map:
      "My Show: The Movie": "My Show Presents The Movie"
```

## `credentials`

- **Type:** `dict` keyed by service tag  ·  **Default:** `{}`

Per-service login credentials. Each value is a `username:password[:extra]` string, the same
data as a `[username, password]` (or `[username, password, extra]`) list, or a dict of profile
name to either of those. With the dict form, `-p/--profile` selects the entry, and unshackle
uses the `default` config key when you give no profile, or when the named profile is missing.
unshackle parses these into `Credential` objects. It also uses the credential's SHA-1 as an
account hash for cache keys.

```yaml
credentials:
  EXAMPLE2: user@example.com:hunter2
  EXAMPLE1:
    default: primary@example.com:pw1
    second: secondary@example.com:pw2
```

!!! tip "Cookies vs credentials"
    unshackle stores cookies as files under [`directories.cookies`](directories.md), not in this config key.
    A service's `authenticate()` accepts cookies, credentials, or both.

## `firefox_cookies`

- **Type:** `dict` keyed by service tag  ·  **Default:** `{}`

Settings for extracting cookies directly from a local Firefox profile. A service block must give
`hosts`, a list of cookie hostnames. unshackle ignores an entry shorter than 3 characters, to
prevent a broad match dumping most of the profile. With an optional `local_storage` boolean,
unshackle also pulls matching entries from `webappsstore.sqlite`, which only services that keep
auth tokens in localStorage rather than in HTTP cookies need. Extraction is read-only.

!!! note "Firefox does not need to be closed"
    The extractor copies **both** `cookies.sqlite` **and** its WAL file into a `0700` temp
    directory, so the copy holds the writes Firefox has not yet flushed to the main DB. Extraction
    fails only if Firefox holds an exclusive write lock at the instant of the copy. The live
    profile is not modified.

!!! warning "Extraction falls back silently to file cookies"
    If extraction yields no cookies or fails for **any** reason, unshackle silently falls back
    to the normal file-based cookie path (`cookies/<SERVICE>.txt` or
    `cookies/<SERVICE>/<profile>.txt`), with no error reported.

## `remote_services`

- **Type:** `dict` &nbsp;·&nbsp; **Default:** `{}`

Definitions of remote unshackle service servers, used by the `--remote` mode. Each entry is
named by you (pick it with `--server`, or do not write that flag when you configure only one) and gives
the server's `url` (required), an optional `api_key`, an optional `auth_headers` list, an
optional `server_cdm` boolean, and an optional `services` sub-dict of per-service local
overrides such as `title_map`.

Leave `server_cdm` unset and the client follows the server: it uses the server CDM for each
service the API key has it on, and the local CDM for the others. `true` asks for the server CDM
and falls back to the local CDM when the server refuses; `false` always uses the local CDM.

`auth_headers` lists extra header names to send the API key in, tried before the defaults
`X-Secret-Key` and `X-Api-Key`, which are always appended as fallbacks. unshackle sends the
first name. If the server answers `401`, it retries the same request with the next name, and
keeps the one that works for the rest of the HTTP session. Names you give keep your spelling and
are not repeated in the fallbacks, so unshackle tries
`auth_headers: ["Authorization", "x-secret-key"]` as `Authorization`, `x-secret-key`, `X-Api-Key`.

In `--remote` mode unshackle turns the server's service list into synthetic CLI
commands that operate against it, falling back to the tags in that `services` sub-dict when
unshackle cannot fetch the list. Each synthetic command carries the server-side service's options and
documentation, so `unshackle dl --remote <TAG> -h` shows the same help text as it does on the
server. See [remote sessions](../../dev/rest-api/remote-sessions.md) for the
full setup.

## `serve`

- **Type:** `dict` &nbsp;·&nbsp; **Default:** `{}`

Configuration for the `serve` command (the built-in REST API server). The full server guide
is the [REST API](../../dev/rest-api/index.md) section. These are the config keys.

| Sub-key | Type | Default | Description |
|---------|------|---------|-------------|
| `api_secret` | str | *(unset)* | Master secret accepted in the `X-Secret-Key` header. Required unless the server is started with `--no-key`. |
| `users` | dict | `{}` | Per-user API keys and their allowlists (see below). |
| `services` | list | *(unset)* | Global service allowlist. Omit to allow all. |
| `remote_only` | bool | `false` | Expose only the remote service session endpoints (health, services, search, session) and disable the rest of the REST API. |
| `session_ttl` | int (s) | `300` | Lifetime of an interactive auth session. |
| `max_sessions` | int | `100` | Maximum concurrent sessions. |
| `history_limit` | int | `100` | How many finished jobs to retain in history. |
| `compression_level` | int | `1` | gzip level for responses. |
| `services_refresh_interval` | int (s) | `0` | How often the server pulls the git-backed service repositories in `directories.services` and hot-reloads the services that changed. `0` turns it off. A service with a running or queued job swaps to the new code as soon as its last job finishes. |
| `global_speed_limit` | str | *(unlimited)* | Server-wide download speed cap, e.g. `10M`, `1.5G` or plain bytes/sec (same format as `speed_limit`). One shared budget across all concurrent jobs; per-job speed limits are ignored while it is set. |
| `cdm_overrides` | list or bool | *(unset)* | Allowed per-request CDM overrides: a list of permitted device names, or `true` for any. Unset rejects every override. |
| `allow_job_credentials` | bool | `false` | Permit clients to supply credentials per job. |
| `devices` | list | *(auto)* | Widevine devices offered; auto-filled from `directories.wvds`. |
| `playready_devices` | list | *(auto)* | PlayReady devices; auto-filled from `directories.prds`. |

Each entry under `users` uses that user's API key as its name, and can set its own `services`,
`devices`, and `playready_devices` allowlists, narrowing the global ones, plus an optional
`username` used as the log label for that API key (defaults to a truncated form of the API key).
A user with no `playready_devices` config key gets no PlayReady access at all, not the global
list.

`server_cdm` decides whether the server runs the CDM licensing for that API key. Set it to
`true` to enable every service, or to a list of service tags to enable only those. It is `false`
unless the entry sets it. For a service the API key does not cover, the server tells a remote
client configured with `server_cdm: true` to license with its own local CDM instead, and a
client that asks anyway gets a `FORBIDDEN` error. Because a download job always licenses with the server's CDM,
an API key without `server_cdm` for that service also cannot submit or retry `/api/download`
jobs. Keys that have no `users` entry, such as `api_secret`, keep server CDM access.

```yaml
serve:
  api_secret: change-me
  remote_only: true
  services: [EXAMPLE1, EXAMPLE2]
  services_refresh_interval: 3600   # pull the service repositories hourly and reload what changed
  # server-wide download defaults (same keys as the `dl:` block)
  downloads: 3
  best_available: true
  users:
    a1b2c3d4:                     # this user's API key
      services: [EXAMPLE1]        # may only use EXAMPLE1
    e5f6a7b8:
      server_cdm: true            # this key may have the server do the licensing
    c9d0e1f2:
      services: [EXAMPLE1, EXAMPLE2]
      server_cdm: [EXAMPLE1]      # the server licenses only EXAMPLE1; EXAMPLE2 needs a local CDM
```

!!! note "`dl` keys inside `serve`"
    Most [`dl`](download.md#dl) flag keys (`downloads`, `workers`, `best_available`, and so on)
    can be set directly inside `serve`, where they apply to every request the server handles.
    The server recognises a fixed subset of download parameters, so a few CLI-only flags are
    ignored here.
