{% hint style="info" %}
CrossWatch uses TMDb for many features.

TMDb is strongly recommended if you want posters, backdrops, richer metadata, and more reliable matching.
{% endhint %}

### Setup

{% stepper %}
{% step %}

### Create a TMDb API key

1. Create a TMDb account.
2. Request an API key here: <https://www.themoviedb.org/settings/api>
   {% endstep %}

{% step %}

### Add the key to CrossWatch

1. Open **Settings → Connections**.
2. Paste your API key.
3. Click **Save**.
   {% endstep %}
   {% endstepper %}

{% hint style="info" %}
This key is used for matching only.

If you want TMDb watchlist/ratings syncing, connect **TMDb Sync** instead: [TMDb](/crosswatch/settings/connections/trackers/tmdb.md).
{% endhint %}

### Settings

<details>

<summary>Language / Locale</summary>

Controls the language used for titles, overviews, and other localized fields.

PublicMetaDB TMDb enrichment uses this setting too.

Pick a locale code from the list below.

</details>

<details>

<summary>Cache TTL (hours)</summary>

Controls how long CrossWatch caches posters and other TMDb payloads.

PublicMetaDB TMDb enrichment uses this cache too.

Default is `720` hours.

Higher TTL = fewer API calls.\
Lower TTL = fresher metadata.

</details>

### Supported locales

These locale codes control the language/region used for TMDb lookups.

* `tmdb.api_key`

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.crosswatch.app/crosswatch/settings/connections/metadata/tmdb-metadata.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
