How this service works
QuietSignal Public Data: independent, read-only rollup, wallet, opportunity, and developer-data facts for agents, paid per request with USDC over HTTP 402 on Base.
Output
Returns a JSON object with a policy schema version, a policies map (e.g. uses_https: true/false, has_strict_transport_security: true/false), the HTTP status code of the final response, the number of redirects followed, and a disclaimer that results reflect observed public signals only and are not a security audit.
Example use cases
Security audit of partner domain
“Check whether https://partner-api.acme.com enforces HTTPS and has HSTS set — I want to know if it's safe to integrate with, following at most 3 redirects.”
Pre-launch HTTPS compliance check
“Before we go live, can you verify that https://myapp.io is correctly serving over HTTPS and has strict transport security headers in place?”
Redirect chain investigation
“Can you inspect https://old-domain.com and tell me how many redirects it follows and whether the final destination uses HTTPS, with a max of 5 redirects?”
Technical details
Endpoint
GEThttps://83-29-153-50.sslip.io/v1/http-policy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, machine-readable read on a public URL's HTTP transport security posture — specifically HTTPS usage and HSTS — without running a full security scanner. It is ideal for lightweight pre-integration checks, compliance spot-checks, or automated pipelines that need per-URL policy facts at low cost ($0.02/call) via USDC on Base.
Side effects
- Invalid or malformed URL returns a validation error
- URL is unreachable or times out causing a failed probe response
- Redirect count exceeds the specified max_redirects limit, halting traversal early
- Non-public or private IP URLs may be rejected
- Payment failure over HTTP 402 if USDC balance is insufficient
