SundaySky

SundaySky is an enterprise video personalization platform that uses AI to create, edit, and deliver dynamically personalized videos at scale. The platform lets organizations tailor video content to individual viewers using customer data and real-time rendering, serving customer experience, marketing, sales, and learning-and-development teams — with particular traction in regulated industries such as financial services, insurance, telecom, and healthcare. Its products include SundaySky Studio for content creation, the SundaySky Player, a Landing Page Builder, and analytics and reporting. SundaySky publishes one documented HTTP API — the SundaySky Video API, a storage-less POST endpoint at apis.sundaysky.com that accepts a flat JSON payload of viewer personalization fields and returns a base64 player session used to render a video in real time — alongside a data-connector marketplace (Salesforce, HubSpot, Snowflake, Databricks, Google Sheets, Marketo, file upload, URL parameters) and a client-side player web component with a documented browser event surface. There is no self-serve developer portal, no published OpenAPI, and no public pricing; platform access is sold and provisioned to enterprise customers. This profile was surfaced as a portfolio company of Norwest Venture Partners and enriched by the API Evangelist pipeline.

SundaySky publishes 1 API on the APIs.io network. Tagged areas include Company, Video, Personalization, Video Personalization, and Marketing.

SundaySky’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, authentication, and 20 more developer resources.

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/sundaysky: open an issue to ask a question, or submit a pull request to add artifacts.

  description: Storage-less HTTP API for real-time personalized video rendering. The caller POSTs a flat JSON object of viewer
    personalization fields (mapped in the SundaySky Studio data library) to the player-session endpoint for a given SundaySky
    Video ID; SundaySky renders a personalized video in real time and returns a base64 string that the SundaySky player consumes,
    or that can be decoded to extract the video stream URL and captions URL for use in a third-party player. Personalization
    data is purged after the video is generated.
