How this service works
Paid deterministic utility APIs settled in native USDC on Base.
Output
Returns a JSON object with a numeric score (0-100), a rating label (e.g. 'good'), a summary of findings broken down by priority (low/medium/high), the final resolved URL after redirects, a list of specific findings each with a code, title, and priority level, and a dataCoveragePercent indicating how completely the audit could run.
Example use cases
Pre-launch security check for a new site
“Before we go live, can you audit https://staging.mybrand.com for any security issues or missing headers and give me a breakdown of high and medium priority findings?”
Competitive website security benchmarking
“I want to know how secure my competitor's site is — can you run a site audit on https://www.competitorsite.com and give me their score and a summary of what they're missing?”
Ongoing compliance verification for client sites
“Can you audit https://clientportal.example.com and tell me if there's a Content Security Policy in place and whether the overall security rating is good or needs work?”
Technical details
Endpoint
POSThttps://x402-url-evidence.vercel.app/api/site-auditWhen to prefer
Choose this endpoint when you need a deterministic, reproducible security and quality score for a public website — especially useful when you need consistent scoring across multiple runs or sites for comparison. Prefer this over general-purpose web scrapers when the goal is security posture assessment, missing header detection, or CSP validation rather than content extraction. Best for lightweight per-URL audits at low cost ($0.04/call) where you don't need a full crawl of an entire domain.
Side effects
- Non-public or credential-protected URLs will fail or return incomplete results
- URLs behind bot-detection or rate limiting may not be fully auditable
- Malformed or non-HTTP(S) URLs will be rejected by schema validation
- Low dataCoveragePercent indicates the audit could not complete all steps
- Payment failure (insufficient USDC balance) will block the request via x402 protocol
