# Agri Halowerk Supply Spoilage Calculator

> Agri Halowerk Supply Spoilage Calculator is a paid API for AI agents from agri.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Converts temperature history segments into equivalent ageing at a reference temperature using a Q10 factor, then compares accumulated ageing against nominal shelf life to estimate spoilage status.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agri-halowerk-supply-spoilage-calculator-3273be09 -d '<json body>'
```

Example prompt: Our strawberry shipment spent 12 hours at 2°C, then 6 hours at 10°C, and finally 8 hours at 5°C — the nominal shelf life is 7 days, reference temperature is 4°C, and we're using a Q10 factor of 2.5. Can you calculate how much shelf life has been consumed and whether the batch is still within spec?

## When to prefer this

Choose this endpoint when you need a fast, deterministic Q10-based calculation of equivalent thermal ageing for perishable goods across multiple temperature segments. It is ideal for supply chain agents tracking cold-chain history for produce, dairy, pharmaceuticals, or other temperature-sensitive goods. Prefer it over manual calculations or spreadsheets when temperature logs have many segments. Do not use it as a food-safety authority, microbial model, or regulatory certification tool.

## Known failure modes

- Invalid Q10 factor outside 1–20 range returns validation error
- Temperature values outside -100°C to 200°C are rejected
- Duration values of zero or negative are rejected
- Array exceeding 10,000 segments returns payload-too-large error
- Missing required fields returns 400 bad request
- Nominal shelf life of zero or negative is rejected

## How this service works

Converts each supplied storage segment into equivalent ageing at a reference temperature using a caller-supplied Q10 factor, then compares the sum with nominal shelf life. This empirical approximation is not a microbial model, food-safety decision, sensor feed, cold-chain certification or release authorization.

## Output

Returns the total equivalent ageing accumulated (in days at the reference temperature) and a comparison against the nominal shelf life, indicating whether the product is within or has exceeded its expected shelf life. Does not include microbial modeling, food-safety certifications, or regulatory release decisions.
