How this service works
Ecommerce ops data paid per call over x402 (Base USDC, PayAI facilitator).
Output
Returns a JSON object with the fetched product page's HTTP status, JSON-LD block count, extracted schema.org Product fields (name, SKU, GTIN, brand, MPN, image, price, currency, availability, condition), Open Graph tags (title, price, currency, availability), an array of field-level checks each with a status and GMC impact rating, a summary of required missing fields and warnings with an overall readiness label, a suggested next step endpoint, fetch timing in milliseconds, and a disclaimer about the automated nature of the check.
Example use cases
Pre-launch GMC readiness audit
“Before I submit my new product feed to Google Merchant Center, can you check if https://www.example-store.com/products/wireless-headphones-pro has all the required structured data — I need to know if name, GTIN, brand, price, and availability are all present and valid.”
Debugging missing product fields
“My product at https://shop.mybrand.com/products/leather-wallet keeps getting disapproved in Google Shopping — can you run a schema check on that page and tell me exactly which required fields are missing and what warnings came up?”
Competitor product page audit
“I want to see how well https://www.competitor-store.com/products/running-shoes-v2 is set up for Google Shopping — check what structured data it has, whether JSON-LD is valid, and give me a readiness score.”
Technical details
Endpoint
GEThttps://x402-niche-briefs.fly.dev/v1/product-schema-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, per-URL structured data audit of a public ecommerce product page — specifically to assess Google Merchant Center readiness, validate schema.org Product JSON-LD fields, and identify missing required or recommended fields. Prefer this over general SEO crawlers when you specifically need GMC-focused field-level diagnostics (GTIN, MPN, condition, availability) and Open Graph tag extraction in a single lightweight call at $0.005 per check.
Side effects
- Non-public or paywalled product URLs return fetch errors or empty schema results
- Pages with no JSON-LD or Open Graph markup will have product_found=false and empty product fields
- Network timeouts or slow product pages may result in high fetch_ms or errors
- Redirected URLs are followed to final_url but intermediate failures may occur
- Malformed JSON-LD on the page is counted in invalid_jsonld_blocks rather than parsed
- Non-product URLs (category pages, homepages) will not yield valid product data
