LISTENING TO THE TAPE…
Developers · API v1
Built for bots.
Readable by humans.
REST snapshots for ranking jobs, typed signal envelopes for automated systems, and a versioned ontology that pins every field to a public formula.

REST is the live transport today. The websocket stream from the mock remains a transport brick; the event envelope is already stable enough to inspect.
The contract
Versioned. Fingerprinted. Never silent.
Consumers can pin the exact SSO fingerprint they validated against. New fields are additive; missing values stay visible instead of being hidden.

Endpoints
The public tape surface.
These are the routes a dashboard, bot, or archive job can consume without guessing what each number means.
