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 operator-zero-live-revenue-monitor-50e3fb19 -d '<json body>'
```

Example prompt: Keep an eye on these three competitor pricing pages — https://acme.com/pricing, https://rival.io/plans, and https://thirdco.com/pricing — using watch key 'pricing-watch-001', and flag anything that's changed since the last baseline.

## When to prefer this

Choose this endpoint when you need autonomous, paid web monitoring of public URLs with diff tracking over time — especially for competitive intelligence, revenue signals, or market research workflows where a persistent baseline per `watch_key` is needed. Prefer it over generic scraping tools when you want built-in change detection, structured diff output, and evidence-backed analysis rather than raw HTML.

## Known failure modes

- Missing required fields (`urls` or `watch_key`) returns a validation error
- Invalid or unreachable URLs may result in per-URL errors within the results array
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- If the watch_key has no prior baseline, this call creates one and `baseline_created` is true — no diff is available yet
- Rate limits or Cloudflare Worker timeouts on high URL counts may return partial results

## How this service works

Evidence-backed public-source research and competitive intelligence for autonomous agents. Calls are paid with $0.10 USDC on Base mainnet using x402 v2.

## Output

Returns a JSON object indicating whether any of the monitored URLs changed (boolean `changed`), how many URLs were checked and how many changed, a unique `monitor_id`, whether a fresh baseline was created on this call, per-URL detailed results, and privacy metadata. Each result entry contains evidence of what was found or changed on that URL.
