How this service works
Fact-preserving listing formatter for Etsy, eBay and Shopify: titles, bullets, description, keyword suggestions, character checks and claim-risk flags. Rules-based, not keyword-volume research or platform compliance certification.
Output
Returns an optimized listing object containing a cleaned product title, improved bullet points, character-limit validation flags, any warnings about the supplied data, provenance notes indicating that facts are customer-supplied and not independently verified, and a list of limitations (e.g. no search-volume or ranking prediction).
Example use cases
Etsy printable art listing polish
“I'm launching a new printable wall art download on my Etsy shop — can you take this title 'Boho Wildflower Print Downloadable Art 8x10' and these three bullets I wrote and optimize them so they're punchy and within Etsy's title character limit?”
Digital kit listing validation
“Before I publish this new seller kit listing on Etsy, can you check that the title is within the character limit and flag any issues with my bullet points for 'Minimal Wedding Invitation Canva Template Editable Digital Download'?”
Bulk new product launch prep
“I'm adding five new linen home goods to my Etsy shop this weekend — can you optimize the listing title and bullets for my 'Sage Green Stonewashed Linen Napkin Set of 4' so everything reads cleanly and passes validation?”
Technical details
Endpoint
POSThttps://signalforgestudios.com/x402/listing-optimizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, fast, low-cost ($0.03) tool to validate and reformat Etsy or similar marketplace listing titles and bullets against character limits. Prefer it over general-purpose LLM rewrites when you need structured JSON output with explicit validation flags and warnings — especially for digital product sellers (printable art, seller kits) who need quick listing hygiene checks before publishing.
Side effects
- Missing or empty title input returns validation error
- Bullet points exceeding platform character limits flagged in warnings array
- No independent verification of product claims — provenance marked as customer_supplied_not_independently_verified
- No search-volume or ranking predictions provided — limitation noted in response
- Malformed request body may result in failed optimization with error response
