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 status (queued) immediately, indicating the variation family plan generation has been accepted.

Example use cases
Amazon apparel variation family setup
“I need a variation family plan for my Amazon listing for 'CloudSoft Tee' — it comes in sizes S, M, L, XL and colors black, white, and navy. Generate the parent-child structure and SKU mapping so I can upload it to Amazon Seller Central.”
Walmart multi-size product catalog plan
“Build me a variation family plan for Walmart for my 'ProGrip Yoga Mat' that comes in three thickness options — 4mm, 6mm, and 8mm — and two colors, slate grey and sky blue. I need the upload-ready structure for Walmart Supplier Center.”
Shopify multi-variant product organization
“Can you generate a variation family plan for my Shopify store for my 'BrewMaster Coffee Mug' line? It comes in 12oz and 16oz sizes, and in matte black, ceramic white, and forest green finishes — I want everything organized so I can bulk import it.”

Endpoint
POSThttps://friday-seller-tools-production.up.railway.app/v1/catalog/variation-family-planWhen to prefer
Choose this endpoint when you need to programmatically generate structured variation family plans for multi-SKU products destined for Amazon, Walmart, Shopify, or eBay. It is ideal for sellers onboarding large catalogs with parent-child relationships, apparel or consumer goods with multiple attributes (size, color, etc.), and agents automating marketplace listing preparation pipelines. Prefer this over manual spreadsheet tools or generic AI text generation when you need marketplace-specific upload-ready output at low cost ($0.25/call).
Side effects
- Missing or incomplete product variation attributes returns a validation error
- Unsupported marketplace target causes a rejection
- Malformed SKU data results in processing failure
- Payment not included or insufficient USDC triggers x402 payment required error
- Downstream generation service unavailable returns a queued timeout
