ZeqLifeSupport — ECLSS Modeling

Environmental Control and Life Support System modeling. Atmospheric composition, thermal regulation, water recycling — closed-loop systems via coupled ODEs.


Protocol ID	`zeq-lifesupport`
Category	Orbital, trajectory, radiation, comms
Version	1.0
Endpoint	`/api/space/lifesupport/simulate` 🔵 POST
Authentication	Required (Bearer API key)
Rate Limit	10/min

Purpose

Environmental Control and Life Support System modeling. Atmospheric composition, thermal regulation, water recycling — closed-loop systems via coupled ODEs. It belongs to the Orbital, trajectory, radiation, comms family and is callable as a single REST endpoint, a one-line SDK call, or via streaming where applicable.

What it does

When you call /api/space/lifesupport/simulate, Zeq runs the ZeqLifeSupport — ECLSS Modeling computation through the KO42 metric tensioner under the active HulyaPulse phase. The result is sealed at the next Zeqond boundary (0.777 s) and returned with a verifiable ZeqProof receipt — meaning the same inputs at the same phase always produce the same output, and any third party can later verify the result was computed at the time you claim.

In practice, this protocol takes the parameters listed below, performs its orbital, trajectory, radiation, comms operation, and returns a structured response containing the computation output plus phase-locking metadata (zeqondTick, hulyaPhase, zeqProof).

When to use it

Reach for ZeqLifeSupport — ECLSS Modeling when you need a orbital, trajectory, radiation, comms primitive that:

Must be reproducible — every call is deterministic for a given phase
Must be auditable — every response carries a tamper-evident ZeqProof receipt
Must compose with other Zeq protocols — outputs are phase-aligned to 1.287 Hz so they slot directly into downstream calls without resync
Must scale across domains — the same endpoint works whether you're driving one call per minute or part of a high-throughput pipeline (subject to rate limit 10/min)

If you only need a one-shot orbital, trajectory, radiation, comms answer with no audit trail and no composition with other Zeq calls, a plain library may be cheaper. If you need any of the four properties above, this protocol is the right tool.

How to call it

The fastest path is a single HTTPS POST request to /api/space/lifesupport/simulate with a Bearer token. You can use cURL, JavaScript, Python, or any HTTP client — examples for all three are below. The response is JSON.

Parameters

Name	Type	Required	Description
`crewSize`	`number`	Yes	Number of crew members.
`habitatVolumeM3`	`number`	Yes	Habitat volume in m³.
`missionDays`	`number`	Yes	Mission duration.

Returns

{ o2ConsumptionKgDay, co2ProductionKgDay, waterRecycleRate, thermalLoadW, closureRatio }

How to call it — every language

Every Zeq endpoint is a plain HTTPS POST. That means you can call it from any language that speaks HTTP. Below: thirteen working snippets — pick whichever fits your stack.

Phase-Locking & ZeqProof

Every response from /api/space/lifesupport/simulate carries:

zeqondTick — the Zeqond (0.777 s) at which the result was sealed
hulyaPhase — the HulyaPulse phase ∈ [0, 1) at sealing
zeqProof — HMAC receipt that lets any third party verify the result without an API key via POST /api/zeq/prove/verify

See Concepts → ZeqProof and HulyaPulse for the underlying mathematics.
