How this service works
Add-to-cart action experiment plan 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 report containing the observed add-to-cart evidence gathered from the target URL, the evaluation threshold, a pass/fail/inconclusive verdict, the exact source of the evidence, any limitations of the passive inspection, and a mode-specific recommended experiment action. No login, purchase, or form submission is performed.
Example use cases
Pre-launch conversion readiness check
“Before we go live with our new product page at https://staging.mybrand.com/products/sneaker-x, can you run the add-to-cart experiment plan and tell me if it passes the conversion threshold and what action we should take?”
Competitor add-to-cart benchmarking
“I want to understand how a competitor's add-to-cart experience stacks up — can you evaluate https://www.competitorstore.com/products/flagship-item using the add-to-cart experiment plan and give me the verdict and evidence source?”
Regression check after site redesign
“We just redesigned our checkout flow — can you compare the add-to-cart experiment plan results for https://mystore.com/products/main-item against our previous baseline snapshot to see if anything regressed?”
Technical details
Endpoint
POSThttps://conversion.halowerk.com/v1/add-to-cart-experiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a passive, non-destructive experiment plan specifically focused on the add-to-cart action on a public product page. It is distinct from the audit and decision siblings in that it returns an actionable experiment recommendation rather than just a verdict or audit log. Prefer this when you want to know not just whether the add-to-cart element passes criteria, but what experiment to run next.
Side effects
- Target URL is unreachable or returns a non-200 status — endpoint may return an error or inconclusive verdict
- Target page requires authentication, making add-to-cart elements invisible to passive inspection
- Add-to-cart element is dynamically rendered and not present in the crawled HTML, limiting evidence
- Malformed or non-HTTP(S) URL provided, triggering a validation error
- Rate limiting or bot-blocking by the target server preventing evidence retrieval
