## 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 personal-weighted-decision-matrix-cdf90597 -d '<json body>'
```

Example prompt: I need to pick between three apartment options — Option A, B, and C — and my criteria are rent (weight 3), commute time (weight 2), and size (weight 1); their scores are A:[7,6,8], B:[5,9,6], C:[9,4,7] — can you run a weighted decision matrix and tell me which one wins?

## When to prefer this

Use this endpoint when a user needs a structured, quantitative comparison of multiple personal options against weighted criteria — particularly for personal (non-enterprise) decision-making workflows. Prefer this over manual ranking or generic LLM reasoning when reproducibility and numeric weighting matter.

## Known failure modes

- Mismatched array lengths between scores and criteria result in computation errors
- Missing or empty options/criteria arrays may return errors or empty results
- Non-numeric scores or weights may cause validation failures
- Negative weights or scores outside expected range may produce unexpected rankings

## How this service works

Personal Weighted decision matrix: Score options against weighted criteria. Tailored for personal workflows.

## Output

Returns a weighted score for each option computed by multiplying each criterion's weight by the option's score for that criterion and summing across all criteria, allowing the agent to rank options and identify the highest-scoring choice.
