## 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 conway-replicatio-url-compare-a2063ca6 -d '<json body>'
```

Example prompt: Can you compare these two URLs for me and tell me what's different between them: https://example.com/page-v1 and https://example.com/page-v2?

## When to prefer this

Choose this endpoint when you need to programmatically compare the content or responses of two public URLs in a pay-per-call, agent-friendly context with USDC micropayment settlement. Best for one-off or automated comparisons where you need a structured result rather than a manual side-by-side review.

## Known failure modes

- Invalid or unreachable URLs return an error with ok: false
- Non-public or private URLs may be blocked for security reasons
- URLs that return non-standard content types may not compare cleanly
- Timeout if either URL is too slow to respond
- Malformed URI format in url or compareUrl triggers schema validation failure

## 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 an 'ok' boolean, a 'data' object containing the comparison result between the two URLs, and a 'capability' field confirming this was the mg-x402-ready-compare endpoint. The data field contains the structured diff or similarity analysis between the two fetched URLs.
