Firefly

Firefly Systems Inc. is a data-first moving out-of-home (mOOH) advertising network that turns taxis, rideshare vehicles, and other mobility assets into digital and static advertising surfaces across 15+ major North American markets and several countries. Its network of tens of thousands of GPS-connected screens delivers geo-targeted, contextual, and programmatic digital out-of-home (DOOH) campaigns with advanced tracking, attribution, and measurement. Firefly offers digital and static car tops, full and partial car wraps, in-car TaxiTV, around-car activations, and experiential LED and hologram truck formats. Programmatic demand reaches Firefly inventory through third-party DOOH supply-side platforms rather than a Firefly endpoint — its own advertising-solutions page names Place Exchange, Vistar Media, Hivestack and Broadsign, alongside a VIOOH integration, and supports Programmatic Guaranteed and open-marketplace deals. The company is backed by investors including 500 Global, Andreessen Horowitz (a16z), and GV (Google Ventures).

Firefly is profiled on the APIs.io network. Tagged areas include Company, Advertising, Digital Out-of-Home, DOOH, and Mobility.

Firefly’s developer surface includes engineering blog, support, authentication, and 12 more developer resources.

  note: Round 2. Contract discovery widened from 4 hosts to 8 and still found no Firefly OpenAPI, GraphQL, AsyncAPI, MCP server
    or agent card. The only machine-readable documents Firefly serves are the OIDC/RFC 8414 metadata on its Auth0 custom domain,
    which now back the authentication/ and scopes/ artifacts. plans/ and rate-limits/ record measured zeros and deliberately
    carry NO pointer, since a pointer would assert a surface the provider does not publish.
x-coverage:
  state: gated
  reason: marketplace-only
  detail: Firefly ships no developer site of its own — fireflyon.com/developers, /api, /docs and /pricing all 404 and its
    90-URL sitemap contains no reference page — and the only live Firefly API host, the advertiser-dashboard gateway app-gw.api.fireflyon.com,
    answers 404 text/plain to every unauthenticated path including /openapi.json; the integration surface a buyer actually
    programs against is Firefly's inventory listed inside third-party DOOH SSPs (Place Exchange, Vistar Media, Hivestack,
    Broadsign, VIOOH), whose OpenRTB contracts belong to those platforms rather than to Firefly.
