How this service works
TIP-OF-SPEAR: URL Fingerprint ($0.01) GET ?url= → body_sha256/TLS/DNS. DEMAND-MATCHED SERP tip: Web Search ($0.02) GET ?q= (required) → ranked results. OCR tip: Image OCR ($0.01) GET ?url= → Tesseract text (COGS=0). Builder tool: Bazaar Readiness Check — FREE ?url= indexed yes/nein + issue count; PAID report $0.05 Fix-JSON. Gated-data: Base DeFi Snapshot ($0.03) balances+gas+protocol TVL/APY. Free teasers have no live hash/results. Upsell red-flag $0.25. Ladder: 0.01→0.02→0.025→0.25→0.35→0.49→0.75→17.
Output
Returns a JSON object containing the body_sha256 (SHA-256 hash of the response body), TLS certificate details (issuer, expiry, protocol version), DNS resolution info, final resolved URL after redirects, and HTTP status code.
Example use cases
Content change detection for a webpage
“Fingerprint https://competitor-site.com/pricing for me — I want the body SHA-256 so I can compare it against last week's hash and know if their pricing page changed.”
TLS and DNS audit of a domain
“Check the TLS certificate and DNS details for https://api.myvendor.com — I want to make sure their cert is valid and see what's actually resolving.”
Content integrity verification before processing
“Before I process this file, can you fingerprint https://downloads.example.com/dataset.csv and give me the SHA-256 hash so I can verify it matches the one I was sent?”
Technical details
Endpoint
GEThttps://geld-machen-x402.fly.dev/product/url-fingerprintWhen to prefer
Choose this endpoint when you need a cheap ($0.01), deterministic, server-side fingerprint of a URL including its body hash, TLS, and DNS — especially for change detection, integrity verification, or security auditing. Prefer this over client-side fetching when you need consistent hashing from a neutral vantage point, or when you want TLS/DNS metadata alongside the content hash in a single call.
Side effects
- Non-HTTPS URL provided — endpoint requires an https:// URL
- URL is unreachable or times out — returns error with no fingerprint data
- Invalid URL format — returns 400-class error
- Payment not fulfilled — returns HTTP 402 requiring $0.01 USDC payment
- Target URL blocks the crawler — may return incomplete or error response
