Native API (/v5)

ZNSI’s own API: minds and turns, explicit neuron budgets, memory scopes as resources, and the Harmony annotation every turn carries.

Every response on this page was returned by the API when the page was built.

GET /v5/models

List models (native).

Models with their neuron limits, first-token latency and context.

Errors

  • 400 Invalid request: a missing or invalid parameter, named in param.
  • 401 No key, or a key that is malformed, expired or revoked.
  • 404 Unknown route or model.
  • 413 Request body larger than 10 MB.

POST /v5/minds/{model}/turns

Take a turn.

One turn with a mind, with an explicit neuron budget. Every turn carries a Harmony annotation: the monitor that classified the update it caused, its coverage, and whether the update was classified or queued for human review.
