How this service works
Add-to-cart action audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
Output
Returns a structured audit result containing: the observation (what was found on the page), the criterion threshold being evaluated, a pass/fail verdict, the exact evidence source URL, any limitations of the passive check, and a mode-specific recommended action for improvement.
Example use cases
E-commerce conversion health check
“Audit the add-to-cart flow on https://mystore.com/products/wireless-headphones and tell me whether it passes conversion best practices — I want the observation, the verdict, and what's limiting performance.”
Competitor checkout benchmarking
“Inspect the add-to-cart experience on https://competitor.com/product/running-shoes and give me a verdict on how their checkout entry point stacks up, including what evidence you found and any limitations.”
Before-and-after redesign comparison
“Compare the add-to-cart audit for https://mysite.com/product/laptop-bag against my previous baseline snapshot — did the redesign improve the conversion verdict, and what changed in the evidence?”
Technical details
Endpoint
POSThttps://conversion.halowerk.com/v1/add-to-cart-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, passive, read-only verdict on whether a public product page's add-to-cart experience meets conversion criteria — without logging in, injecting payloads, or performing load tests. It is ideal for quick spot-checks, competitive benchmarking, or monitoring for regressions after page redesigns. Prefer alternatives if you need authenticated audits, full site crawls, or performance load testing.
Side effects
- Target URL is unreachable or returns non-200 status, causing audit failure
- Private or login-gated pages cannot be inspected since no authentication is attempted
- Dynamically rendered add-to-cart buttons may not be visible to a passive crawl
- Invalid or malformed target URL returns a validation error
- Rate limiting or bot-blocking on the target site may prevent evidence collection
- Comparison URL mismatch with target domain may produce inconclusive change results
