KRS Ratings Feed (v1)

The KRS feed publishes a stable, versioned endpoint alongside a moving one. Both return identical JSON. No authentication or API key is required — fetch them directly. This feed currently powers KittyGP.

Stable · recommended

https://www.kittysports.gg/feed/krs/v1/latest.json

Frozen v1 schema. Build integrations against this — it never receives breaking changes.

Moving · latest

https://www.kittysports.gg/feed/krs/latest.json

Always tracks the newest published feed (currently v1).

Driver Strength, projections, and confidence are computed by the KRS engine; supporting signals and market comparison remain sample analytical values — not live odds.

Planned Feed Schemas

Illustrative schemas for planned feeds — not yet live. Each feed returns a consistent envelope with meta and data fields. The meta block always includes a note confirming the data type, a generation timestamp, and schema version.

Driver Ratings Feed

/feeds/v1/driver-ratings

Normalized driver strength ratings with component breakdowns and confidence scores per season and event.

Concepts

Feed Design Concepts

Infrastructure design principles guiding the KittySports feed architecture.

Versioned Schemas

All feeds are schema-versioned. Breaking changes are never deployed to existing endpoints — new versions are published alongside prior versions.

Confidence Metadata

Every rating and projection record carries a confidence score, enabling consumers to filter by certainty level.

Canonical IDs

Drivers, constructors, and events are referenced by stable canonical IDs — not display names — ensuring consistent joining across feed types.

Immutable Records

Projection feeds reflect the model state at generation time. Historical records are never retroactively altered.

Event-Gated Projections

Projection outputs are gated to the event lifecycle — pre-race projections are clearly separated from post-race attribution records.

Batch + Streaming

Planned architecture supports both batch retrieval for historical datasets and streaming delivery for realtime event-day outputs.

Roadmap

Planned Feed Types

Beyond the current feed modules, the following additional feed types are planned as the platform infrastructure matures.

Championship Standings Feed

Live and projected standings with trajectory modeling.

Timing & Session Feed

Sector times, lap records, and session-level timing data.

Market Comparison Feed

Structured comparison of model projections against market-implied lines.

Historical Archive Feed

Deep historical race and session data spanning multiple seasons and categories.

Model-vs-Actual Feed

Post-event projection accuracy records for external calibration analysis.

Partner Entitlements Feed

Custom-scoped feed delivery for partner products with entitlement controls.

The KRS v1 feed is live and free. All other feeds listed here are in planning or development phases.
