How this service works
Product Listing Preflight — one metered assessment.
Output
Returns a JSON object containing: a numeric score (0–100), a verdict string (READY, NEEDS_WORK, or NOT_READY), an array of itemized checks each with id, label, scope, status (PASS/WARNING/FAIL), weight, and detail, pass/warning/fail counts, a summary string, an array of actionable recommendations, a list of missing information fields, keyword observations, and payment receipt metadata.
Example use cases
Pre-launch listing quality check
“Before I publish my new Amazon listing, can you grade it? Title: 'Bamboo Cutting Board Set of 3 – Juice Grooves & Handle', description: 'Eco-friendly, dishwasher safe, anti-slip rubber feet. Great for meal prep.', features: 'set of 3 sizes; juice grooves; non-slip feet; bamboo material', price 34.99 USD, category 'Kitchen & Dining', keywords 'bamboo cutting board, eco-friendly, kitchen', 4 images. Tell me if it's ready or what needs work.”
Comparing listing against strict content rules
“Run a strict preflight check on my Amazon listing and refuse if anything's missing. Title: 'LED Desk Lamp with USB Charging Port', features: 'adjustable brightness; 5 color modes; USB-A port; touch control', price 29.99 GBP, category 'Home Office', keywords 'desk lamp, LED, USB charging', 3 images, no description yet. Use strict mode so I know exactly what's missing.”
Diagnosing a struggling listing
“My Amazon listing isn't converting well — can you score it and tell me what to fix? Title: 'Yoga Mat', description: 'Good mat for yoga.', price 19.99 USD, category 'Sports & Outdoors', keywords 'yoga mat', only 2 images, no shipping or returns info provided. I want the full verdict with all the checks.”
Technical details
Endpoint
GEThttps://listing-grader-ai.lovable.app/api/public/paid-preflight/amazon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, scored, multi-dimensional preflight assessment of an Amazon product listing before publishing — especially when you want itemized PASS/WARNING/FAIL checks, specific recommendations, and a machine-readable verdict. Prefer this over generic content review tools when the goal is Amazon marketplace readiness specifically, or when you need to automate listing QA in an agent workflow at low per-call cost ($0.05).
Side effects
- Missing required query params (title, etc.) when strict=true → returns error indicating missing fields
- Malformed price or currency code → potential validation error or inaccurate score
- Empty or very short description/features → may return NOT_READY verdict with low score rather than an error
- Payment failure (x402) → 402 response before assessment is run
- Rate or quota limits → HTTP 429 or payment-gating response
