Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/comcast: open an issue to ask a question, or submit a pull request to add artifacts.

  description: Firebolt is Comcast's application platform for building apps that run on TVs, set-top boxes, and other connected
    home devices. The Firebolt SDK exposes a family of JavaScript APIs (Lifecycle, Metrics, Device, Authentication, Discovery,
    Profile, Localization, Account) that let developers write once and deploy to any supported device. Firebolt is defined
    with OpenRPC and ships as a publicly hosted npm package (@firebolt-js/sdk) with zero runtime dependencies.
  x-features:
  - OpenRPC-defined JSON-RPC interface across modules
  - Lifecycle, Metrics, Device, Authentication, Discovery, Profile modules
  - JavaScript SDK distributed via npm with zero dependencies
  - Reference implementations and certification tooling
  - Targets Xfinity X1, Xfinity Flex, Sky Q, and other connected devices
  x-use-cases:
  - Building streaming/entertainment apps for Comcast set-top boxes
  - Cross-device TV app distribution from a single codebase
  - Capturing standardized app health and usage metrics
  - Driving sign-in/entitlement flows on connected TV devices

    to Comcast partner APIs such as the Open Ingest service. Clients exchange an x-client-id and x-client-secret pair for
    an OAuth-style access token valid for 24 hours, which is then attached to subsequent requests in the Authorization header.
  x-features:
  - Client-credential token exchange
  - 24-hour bearer token lifetime
  - x-client-id / x-client-secret request headers

    Clients POST an XML payload describing assets to the Merlin ingest proxy, authenticated with a Comcast SAT bearer token
    and partnered through partner identifiers such as globalott. The endpoint returns an OpenIngestResult document with per-asset
    outcome status.
  x-features:
  - XML asset and metadata submission
  - Bearer-token authentication via Comcast SAT
  - Partner-scoped ingestion (e.g. globalott)
  - OpenIngestResult outcome reporting
  x-use-cases:
  - Submitting media metadata to NBCUniversal pipelines
  - Bulk content publication for OTT distribution
