How this service works
Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.
Output
Returns a job_id and a status field (e.g. 'queued') indicating the claim-check job has been accepted for asynchronous processing. The agent should poll or retrieve results using the returned job_id from a companion endpoint.
Example use cases
Pre-launch Amazon listing audit
“Before I publish this Amazon US listing, can you check the product description for any forbidden claims? The text is: 'Clinically proven to reverse hair loss and approved by dermatologists.' Forbidden claims are 'clinically proven to reverse' and 'approved by dermatologists'.”
Walmart compliance screen for health product
“I need to validate my Walmart product copy before uploading. The text says 'This probiotic eliminates gut inflammation and is doctor-recommended.' Flag anything that counts as an unverified or forbidden claim — forbidden ones are 'eliminates gut inflammation' and verified ones are 'supports digestive health'.”
eBay listing review for electronics
“Can you run a claim check on this eBay listing for a battery pack? The text is: 'Charges 3x faster than any competitor, lasts 10 years guaranteed, and is UL-certified.' Mark 'lasts 10 years guaranteed' as forbidden and 'UL-certified' as verified.”

Endpoint
POSThttps://friday-seller-tools-production.up.railway.app/v1/listing/claim-checkWhen to prefer
Choose this endpoint when you need to pre-screen product listing text for marketplace policy compliance before uploading, especially when you have known forbidden or verified claim sets to check against. It is ideal for e-commerce sellers, content operations teams, or brand managers who need asynchronous, low-cost automated compliance auditing across Amazon, Walmart, Shopify, or eBay — rather than manual review or general-purpose text analysis tools.
