## 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 mg-policy-evidence-compare-80e9fdee -d '<json body>'
```

Example prompt: Can you compare the policy evidence at https://example.com/policy-a and https://example.com/policy-b and tell me what's different between them?

## When to prefer this

Use this endpoint when you need to programmatically compare the content of two public policy or evidence documents by URL — particularly in compliance, insurance, legal, or regulatory workflows where you want a machine-readable diff or analysis without manual reading. It is well-suited for agents that need to flag discrepancies between two versions of a policy page or compare competing vendors' policy evidence.

## Known failure modes

- Invalid or inaccessible URL returns an error (non-public or gated URLs will fail)
- Network timeout if either URL is slow to respond
- Malformed URL format triggers schema validation error
- Non-policy or binary content at the URL may produce empty or low-quality comparison
- Payment failure in USDC/x402 prevents the call from being processed

## How this service works

Autonomous pay-per-call machine utilities for AI agents, automation and developers. Payments settle in USDC on Base through x402.

## Output

Returns a JSON object with ok:true and a data field containing the structured comparison result between the two policy evidence URLs, including identified differences, matching content, and relevant analysis.
