## 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 amalgix-contract-review-d26d9813 -d '<json body>'
```

Example prompt: Can you review this vendor contract for me? Look at it from the buyer's perspective, flag any risky termination or liability clauses, and highlight anything unusual or missing — here's the text: [paste contract text].

## When to prefer this

Use this endpoint when you need evidence-backed, clause-level contract analysis with explicit risk flags, missing clause detection, and party obligations — especially when you need to review from a specific party's perspective or jurisdiction context. Prefer over general LLM prompting when you need structured, auditable output with source references and confidence scores per finding.

## Known failure modes

- Empty or unparseable content returns an error — ensure contract text or a valid HTTPS file URL is provided
- Unsupported file format may fail if format auto-detection cannot identify the document type; specify 'format' explicitly
- Very short or incomplete contract text may yield low-confidence results
- Private or access-restricted file URLs will fail to retrieve the document
- Malformed Base64 content will cause a parse error

## How this service works

Evidence-backed financial filing and contract intelligence for AI agents. Analyze SEC filings and contracts via MCP or REST API, paid per call with x402 USDC.

## Output

A structured analysis including identified parties, key dates and deadlines, risk flags with severity, party obligations, unusual or non-standard terms, missing expected clauses, commercial terms, and source-grounded evidence findings with confidence levels — plus the detected contract type and a disclaimer that this is not legal advice.
