## 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 tradepilotusa-vendor-comparison-bd02bc37 -d '<json body>'
```

Example prompt: I have two vendor proposals for our scheduling improvement project — can you compare them against my brief and tell me which one has better scope clarity, lower implementation effort, and includes staff training? The project is for a two-person crew doing weekday consultations over six weeks.

## When to prefer this

Use this endpoint when you need a structured, AI-generated side-by-side comparison of two or more vendor proposals against a defined project brief — especially when evaluating implementation effort, scope clarity, cost, and training inclusion. Prefer this over manual review when proposals are long or technical and you need a fast, consistent scoring framework. Best suited for SMB procurement, contractor selection, and business operations contexts.

## Known failure modes

- brief or source_text too short (below minLength) — returns validation error
- source_text or brief exceeds maxLength — request rejected
- vague or ambiguous vendor proposals may produce low-confidence comparisons with many evidence gaps
- missing audience field may reduce relevance of comparison framing
- service returns requires_human_review: true for complex or incomplete proposals

## How this service works

Compare supplied vendor proposals against explicit requirements, cost components, risks, and unanswered questions. Uses buyer-supplied information only; no external research or outbound actions. Returns a draft for human review.

## Output

Returns a structured JSON object with a plain-language summary comparing vendor proposals, a markdown-formatted comparison table (scope, cost, effort, training), a list of assumptions made during analysis, identified evidence gaps, a provenance record, a unique request ID, and a requires_human_review flag indicating whether a human should validate the output before acting.
