The Media Ratings Terminal (MRT) is Pixalate's web app for rating ad-supported mobile apps, CTV apps and websites. For each app or domain it shows invalid traffic (IVT), viewability, brand safety, privacy and COPPA signals, made-for-advertising (MFA) risk, traffic sources, authorized sellers and an overall risk rating. You can look up one property, filter millions of them into a list, or upload your own list and check it in bulk. Open the MRT at [ratings.pixalate.com](https://ratings.pixalate.com). *Video (2 min): what the MRT is and what you can do in it.* ## Who uses it * **Advertisers and agencies** vet apps and sites before a campaign and build exclusion and inclusion lists for their partners. * **Platforms (SSPs and DSPs)** vet publishers and partner portfolios, and find properties that share an owner when they optimize supply paths. * **Publishers** see how their own app or site rates on traffic quality, compliance and brand safety, which sellers and inventory sources carry more risk, and how they compare by region and country. ## What it covers | Supply type | What's included | | ----------- | ------------------------------------------------------------------------------------------------------------------------- | | Mobile apps | Apps on Google Play and the Apple App Store, plus bundle IDs that appear in ad traffic but aren't listed on either store. | | CTV apps | Streaming apps on major CTV platforms, such as Roku, Fire TV, Samsung, LG TV and tvOS. | | Websites | Open web domains, with desktop and mobile web traffic. | In the MRT itself these appear as **Connected TV**, **Mobile** and **Website**. Discovery calls websites **Domains**. Most data can be viewed globally or for one region, and app data also by country, device and month. ## Sign in Anyone can create a free account, but a free account sees fewer data points and fewer sections of the MRT. Enterprise clients get an email invitation to finish registering. The MRT uses the same Pixalate account as Pixalate Analytics. See [Sign in and manage your account](/get-started/account-access). For access to more data, contact your Pixalate account manager. ## Find and evaluate apps and sites #### [Search](/mrt/search) Find an app, CTV app or domain by title, ID or keyword, filter the results and download them. #### [Read an Insights report](/mrt/insights) Understand each section of the detail page for one app or domain. #### [Discovery](/mrt/discovery) Filter millions of properties by risk, brand safety, compliance and more, then export the list. #### [Check many apps or domains at once](/mrt/bulk-lookups) Upload a CSV of app IDs or domains and get ratings for all of them. #### [Build exclusion and inclusion lists](/mrt/exclusion-lists) Turn Discovery filters into a list your partners can block or target. #### [Check ads.txt compliance](/mrt/ads-txt) See which domains and apps publish ads.txt or app-ads.txt. #### [Find properties by owner](/mrt/find-by-owner) Use the ads.txt owner domain to list every site or app a company owns. #### [MRT for Slack](/mrt/slack) Look up apps and domains and follow them from Slack. ## Go deeper on a property #### [Audience engagement](/mrt/audience-engagement) How users interact with a site or app and its ads. #### [Seller Insights](/mrt/seller-insights) The trust, performance and compliance of one seller. #### [App spoofing](/mrt/app-spoofing) How Pixalate detects spoofed mobile and CTV apps. #### [CTV bundle IDs](/mrt/ctv-bundle-ids) Why one CTV app can appear under many bundle IDs. #### [Android app permissions and IVT risk](/mrt/android-permissions) How app permissions relate to invalid traffic risk. #### [Find MFA sites and apps](/compliance/mfa-in-mrt) Use the MRT to find made-for-advertising inventory. ## Indexes and rankings #### [Seller Trust Index (STI)](/mrt/seller-trust-index) Rankings of the sellers listed in ads.txt and app-ads.txt, across web, mobile and CTV. #### [Publisher Trust Index (PTI)](/mrt/publisher-trust-index) Monthly quality rankings of websites, CTV apps and mobile apps. #### [SDK Trust Index](/mrt/sdk-trust-index) Ratings of mobile advertising and data collection SDKs. #### [Know Your Developer (KYD)](/mrt/know-your-developer) Ratings of app developers on child safety, privacy compliance and ad fraud risk.

They don't all cover the same features, so pick the one that fits how you work. | | Best for | How you use it | | ------------------------------------------ | -------------------------------------------------------------------------------- | --------------------------------------------------------------------------------- | | **Media Ratings Terminal** | People researching apps and sites, building lists and sharing exports | The web app at [ratings.pixalate.com](https://ratings.pixalate.com) | | **[Enrichment API](/apis/enrichment-api)** | Engineers adding Pixalate ratings to their own systems | REST endpoints for mobile apps, CTV apps and domains, one at a time or in batches | | **[Enrichment MCP](/mcp/enrichment-mcp)** | Anyone who wants to ask an AI assistant about an app or domain in plain language | Connect Claude, ChatGPT, Cursor or another MCP client to Pixalate | The Enrichment API counts usage the same way as the MRT.
