How this service works
Paid x402 API that extracts current pricing, discount and availability from public ecommerce and software pricing pages.
Output
A JSON object containing the extracted product name, current price, original price, discount percentage, currency, availability status (e.g. in_stock), a confidence score for the extraction, and a boolean indicating whether the current price meets the optional target price provided.
Example use cases
Deal alert before buying a gadget
“Check whether this laptop on Amazon is currently discounted and what the current price is — https://www.amazon.com/dp/B09XYZ123 — I'm hoping to pay under £800.”
SaaS plan pricing lookup
“What's the current price listed on Notion's pricing page at https://www.notion.so/pricing? I want to know if the Plus plan is still $10 a month or if it's gone up.”
Ecommerce restock and price check
“Can you check if this pair of trainers is back in stock and what it costs right now — https://www.jdsports.co.uk/product/white-nike-air-max/12345 — and let me know if it's cheaper than £90?”
Technical details
Endpoint
POSThttps://pricecheck-mainnet-production.up.railway.app/price?utm_source=zero.xyzWhen to prefer
Choose PriceCheck when you need to programmatically extract live pricing, discount, and availability data from a specific public product or SaaS pricing URL without scraping infrastructure of your own. It is ideal for price-drop monitoring, budget comparison workflows, or enriching product data pipelines. Prefer it over generic web scrapers when structured pricing fields (current price, original price, discount %, availability) are needed in a clean JSON format ready for agent use.
Side effects
- URL is behind a login wall or paywall — extraction fails or returns low confidence
- Dynamic pricing rendered via JavaScript may not be captured if the page is JS-heavy
- Product page has been removed or returns a 404 — no data extractable
- Ambiguous or multi-product pages may return incorrect product name or price
- Currency detection may fail for non-standard or regional pricing pages
- Low confidence score when pricing layout is unusual or obfuscated
