How this service works
Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.
Output
Returns an async job object with a job_id and status of 'queued'. The agent must poll a separate endpoint using the job_id to retrieve the completed competitor research report containing pricing data, listing structures, keyword usage, and advertising insights for the queried marketplace and product category.
Example use cases
Amazon pricing and listing benchmark
“Look up the top 5 competing listings for 'stainless steel water bottle 32oz' on Amazon — I want to see their prices, how they structure their titles and bullets, and any patterns in how they position the product.”
Walmart competitor keyword research
“Research my competitors selling yoga mats on Walmart and pull together what keywords and descriptions they're using so I can improve my own listing.”
eBay market positioning analysis
“I'm about to list vintage denim jackets on eBay — can you research the top sellers in that category and tell me how they're pricing and positioning their items so I know how to compete?”
Technical details
Endpoint
POSThttps://friday-seller-tools-production.up.railway.app/v1/competitors/researchWhen to prefer
Use this endpoint when an AI agent needs structured competitive intelligence for marketplace selling — specifically pricing benchmarks, listing copy patterns, and advertising strategy insights across Amazon, Walmart, eBay, or Shopify. It is particularly valuable before creating or optimizing product listings, setting prices, or planning ad campaigns. Prefer this over general web search when you need marketplace-native structured data delivered as a ready-to-use deliverable for seller workflows.
Side effects
- Invalid or unsupported marketplace platform returns an error
- Missing required product identifier or search term results in a 400 bad request
- Payment failure via x402 protocol prevents job from being queued
- Async job may fail or time out — polling endpoint may return error status
- Competitor data may be unavailable for niche or low-traffic categories
- Rate limiting if too many concurrent requests are submitted
