How this service works
JSON micro-tool for agents: GET ?url= → deterministic live URL fingerprint (final_url, status, content_type, body_sha256, body_len, tls_issuer/subject, dns A/AAAA sample, fetched_at, timing_ms). Reuses live-fetch bits from red-flag 1.2. Not an essay. Brand: geld machen. x402 $0.01 Base USDC.
Output
A JSON object containing: final_url (URL after redirects), status (HTTP status code), content_type, body_sha256 (SHA-256 hash of response body), body_len (byte length), tls_issuer, tls_subject, dns (object with A and AAAA record samples), fetched_at (ISO timestamp), and timing_ms (round-trip fetch time in milliseconds).
Example use cases
Verify a payment page hasn't been tampered with
“Fingerprint https://checkout.mybusiness.com/pay for me — I need the body SHA256 hash and TLS subject so I can confirm the page content hasn't changed since I last checked it.”
Detect redirect chains on a short link
“Can you fetch https://bit.ly/3xYzABC and tell me what the final URL is after all redirects, along with the HTTP status and content type?”
Monitor a competitor's landing page for changes
“Probe https://competitor.com/pricing and give me the body hash, body length, and timestamp so I can compare it against what I recorded last month.”
Technical details
Endpoint
GEThttps://geld-machen-x402.fly.dev/product/url-fingerprint.jsonWhen to prefer
Choose this endpoint when you need a fast, deterministic, structured fingerprint of a live URL — especially when you need body hashing for change detection, TLS certificate validation, DNS lookup, or redirect chain resolution all in a single call. Prefer it over generic HTTP fetch tools when you specifically need the SHA256 body hash, TLS details, or DNS records alongside the HTTP response metadata.
Side effects
- Non-HTTPS URLs may be rejected or return an error
- Unreachable or offline URLs will result in a timeout or connection error
- URLs returning non-200 status are still fingerprinted but content may be minimal
- Very large response bodies may be truncated or cause slow responses
- Rate limiting or bot-blocking on the target URL may produce partial or blocked responses
- Payment of $0.01 USDC via x402 required; missing payment results in 402 response
