How this service works
BitBooth Web Diff: pay 0.08 USDC, render any URL with full Playwright JS rendering, and receive both the current markdown snapshot AND a structured diff against the previous markdown you supply. Built for monitoring agents tracking competitor sites, docs pages, pricing changes, or any long-running web change-detection workflow. The first call returns the snapshot; pass it back as previousMarkdown next time to get the diff. No API keys, no subscriptions.
Output
Returns a JSON object containing (1) the current full markdown rendering of the target URL captured via Playwright JS, and (2) a structured diff object showing additions, deletions, and modifications relative to the previousMarkdown supplied in the request. On the first call with no previousMarkdown, only the snapshot is returned.
Example use cases
Competitor pricing page monitoring
“Render https://competitor.com/pricing using full JavaScript and diff it against this markdown snapshot I captured last week — tell me exactly what changed in their pricing tiers.”
SaaS docs change detection
“Check https://docs.stripe.com/api/charges for any content changes since my last snapshot and give me a structured diff so I can see what was added or removed.”
Regulatory policy update tracker
“Scrape https://example-regulator.gov/rules/new-policy and compare it to the markdown I saved last month — highlight any new clauses or removed language.”
Technical details
Endpoint
POSThttps://app.heinrichstech.com/v1/cdp/web-diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a fresh rendered snapshot AND a diff in a single atomic call — ideal for long-running monitoring agents that maintain state across calls. Prefer it over a plain render endpoint when change detection is the goal, and over static HTTP fetchers when the page requires JavaScript execution.
Side effects
- Target URL unreachable or returns 4xx/5xx — rendering fails and an error is returned
- JavaScript-heavy pages that time out during Playwright rendering
- Invalid or malformed URL input
- previousMarkdown field contains non-markdown or corrupted text, producing a low-quality diff
- Insufficient USDC payment — request rejected before rendering begins
