How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns the original URL, final URL after redirects, HTTP status code, page title, content size in bytes, SHA-256 hash of the page content, a sample of links found on the page, a payment receipt object, and change detection metadata indicating whether the page differs from previous captures.
Example use cases
Legal compliance content snapshot
“I need to preserve proof of what's currently on https://competitor.com/claims — grab the page content, its SHA-256 hash, and HTTP status so I have timestamped evidence for our legal team.”
Detect unauthorized page changes
“Check https://mystore.com/privacy-policy and give me its SHA-256 hash and change detection data — I want to know if anything has been altered since we last verified it.”
Verify third-party hosted content
“Can you fetch https://partner.com/agreement and return the page title, final URL after any redirects, HTTP status, and a content hash so I can confirm what version of the document is live?”
Technical details
Endpoint
POSThttps://eymqg-159-89-4-32.run.pinggy-free.link/evidenceWhen to prefer
Use this endpoint when you need cryptographic proof (SHA-256) of what a webpage served at a specific point in time — ideal for legal evidence, compliance auditing, change detection workflows, or verifying third-party content. Prefer this over generic scraping tools when tamper-evident hashing and change detection metadata are required alongside the raw content.
Side effects
- URL is unreachable or returns a non-200 HTTP status (still reported but content may be empty)
- URL redirects to a login wall, returning evidence of a gated page rather than intended content
- Very large pages may result in truncated content or timeout
- Invalid URL format in input returns a 400-level error
- Target server blocks automated requests, resulting in misleading or empty content capture
