## 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 agents-bytemine-ai-detect-page-changes-b561fad0 -d '<json body>'
```

Example prompt: Check if Acme Corp's pricing page at https://acmecorp.com/pricing has changed since the last snapshot — I want to know what was added or removed and a summary of what shifted.

## When to prefer this

Use this endpoint when you need to detect what specifically changed on a known company webpage between two points in time, particularly for competitive intelligence tasks like pricing shifts, product updates, team changes, or messaging pivots. Prefer this over a full page analysis when you already have a snapshot baseline and want a diff rather than a full extraction.

## Known failure modes

- No snapshot exists for the given URL yet — the system may return an empty diff or an error indicating no baseline
- URL is inaccessible or returns a non-200 response — the comparison cannot be completed
- Page content is JavaScript-rendered and may not be fully captured — diff may be incomplete
- No meaningful changes detected — added and removed arrays return empty with a summary stating no changes
- Malformed or invalid URL input — returns a validation error

## How this service works

Bytemine is a B2B data platform for sales and go to market teams. It covers contact and company search across 135M professionals and 10M companies, contact and company enrichment, LinkedIn profile search and enrichment, live company intelligence read from a company's own web presence, technographics, buying intent scoring, and hiring, funding, job posting, and job change signals. Search results bill per record returned, enrichment bills only on a successful match, and count queries are free. This server is a pay-per-use, transparent proxy in front of Bytemine's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

Returns an array of added text lines, an array of removed text lines, and a natural-language change_summary describing what shifted between the snapshot and the live page.
