  note: No pricing page, no plans, no signup and no developer portal exist. The only published route to Graffiti is the "Contact
    Us for a Demo" call to action and a name/email/message contact form, so access is enterprise, approval-gated, and not
    self-serve.

description: 451 Degrees is a marketing-technology and ad-tech company founded in 2006 that builds Graffiti, a patented AI
  content ecosystem for digital content and ad-tech businesses. Graffiti uses machine learning, artificial intelligence, and
  natural language processing to analyze user-generated comments and digital content in real time, converting comment "noise"
  into structured data that powers brand safety, contextual relevancy, content recommendation, and first-party data strategies.
  It is designed as a platform-agnostic tool that complements existing comment platforms, ad delivery networks, and content
  systems rather than replacing them, and markets itself as privacy-compliant with GDPR and CCPA while using no cookies, mobile
  IDs, or IDFA for targeting.

  detail: 451 Degrees markets Graffiti as integrating "with simple API construction to current Comment Platforms and Ad Delivery
    Networks" and its own investor one-sheet claims real-time APIs delivered to five ad networks, but the entire public surface
    is a four-page WordPress marketing site whose only developer call to action is "Contact Us for a Demo" — there is no reference,
    no portal, and api./developer./docs./dev./portal.451degrees.com are all NXDOMAIN.
