Parameters

This operation publishes no path, query or header parameters.

Request body

Required. Content type: application/json.

Field	Type	Required	Description
operators	array<string>	no	Operator IDs to run. KO42 sets the metric frame, e.g. ["KO42","GR37","NM19"].
inputs	object<string, number>	no	Named numeric inputs the operators consume (mass, r, v, ...).
consts	object<string, number>	no	Optional constant overrides (t, alpha, f_H, ...).
domain	string	no	Optional domain hint (used by /compute and /auto).
query	string	no	Natural-language problem statement (used by /auto).

Responses

Status	Meaning
200	Sealed result envelope — value, unit, operatorChain, masterEquation, HMAC zeqProof.
401	Missing or invalid credentials
402	Insufficient compute credit

401 body

Field	Type	Required	Description
ok	boolean — one of false	yes	—
error	string	no	Human-readable message.
code	string	no	Stable machine-readable code, e.g. ADMIN_REQUIRED, INVALID_ZID, ZID_NOT_LINKED.
