# Conway Replicatio Web Ground Compare

> Conway Replicatio Web Ground Compare is a paid API for AI agents from conway-replicatio-cloudflare.nikitamakiel1.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Compares two public web pages by fetching and analyzing their content side-by-side, returning a structured comparison result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-web-ground-compare-6929290a -d '<json body>'
```

Example prompt: Compare these two web pages and tell me how they differ: https://example.com/page-a and https://example.com/page-b — I want to know what's different between them.

## When to prefer this

Choose this endpoint when you need a structured, automated side-by-side comparison of two public web URLs, especially in agentic or automation workflows where you want to pay per call with USDC and get machine-readable output. Prefer this over manual scraping when you need both pages fetched and compared in a single API call.

## Known failure modes

- Invalid or unreachable URL — returns error if either URL cannot be fetched or is not a safe public URL
- Non-HTTP URL format — URLs must conform to URI format and be publicly accessible
- Rate limiting or payment failure — x402 payment of 0.1 USDC must succeed before processing
- Timeout — if either page takes too long to load the request may fail
- Malformed request body — missing 'url' or 'compareUrl' fields returns a validation error

## 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

A JSON object with an 'ok' boolean, a 'capability' field identifying the endpoint ('mg-web-ground-compare'), and a 'data' object containing the structured comparison result between the two fetched web pages.
