## 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 legalpulse-sign-check-pre-signature-contract-clearance-d69414e3
```

Example prompt: I just received this freelance service agreement and I need to sign by tomorrow — can you run it through a contract clearance check and tell me whether to sign, negotiate, or walk away, with the specific red flags and what I should push back on? Here's the full contract text: [paste contract].

## When to prefer this

Use this endpoint when a user needs a pre-signature go/no-go recommendation on a specific contract document, especially when they are the non-drafting party (freelancer, tenant, employee, customer, vendor) and need verbatim red flag identification and ranked negotiation priorities. Prefer this over a general contract-explanation endpoint when a decision verdict is required, not just clause education.

## Known failure modes

- Contract text too short or not recognizable as a legal document — returns error or low-confidence result
- Jurisdiction cannot be determined from document content — may return generic multi-jurisdiction guidance
- Contract in unsupported language — may return error or degraded analysis
- Rate limit or payment failure — 402 or 429 error
- Ambiguous party role — may default to generic review without role-specific framing

## How this service works

Pre-signature contract clearance: send the contract text, get a sign / negotiate / walk-away verdict with red flags quoted verbatim from the document, missing protections, key terms, and ranked negotiation asks — reviewed from YOUR side (freelancer, tenant, employee, customer, vendor). Any jurisdiction, auto-detected. Call before you sign.

## Output

A structured verdict (sign / negotiate / walk-away), verbatim red flag quotes pulled directly from the contract, a list of missing protective clauses, a plain-language summary of key terms, and a ranked list of negotiation asks — all analyzed from the non-drafting party's perspective with jurisdiction auto-detected.
