SoldComps VS Feedvisor

SoldComps's answer

It's built API-first for people who want the data, not another dashboard to log into.

No eBay developer account, OAuth flow, or approval process — just an API key and a GET request that returns clean JSON. What you get:

• Up to 240 completed sales per search, across 8 eBay marketplaces (US, UK, DE, FR, IT, ES, CA, AU)
• Fetched live, so results are never stale
• Filters for category, price, condition, and date window

Pricing is per search, not per result — a search that returns 10 items or 240 counts as one request — and there's a free tier with no credit card to start.

SoldComps's answer

SoldComps serves four main audiences:

• Resellers & flippers — price inventory from real sold comps before buying at thrift stores, estate sales, and storage auctions
• Developers — build price-comparison tools, repricers, or valuation features on clean eBay sold data instead of scraping it themselves
• Market researchers — analyze demand, price ranges, and sell-through from completed sales
• Estate-sale & liquidation operators — price large lots quickly

Feedvisor's answer:

Feedvisor helps large sellers, private labels, and brands selling on Amazon, Walmart, and other e-marketplaces.

SoldComps's answer

SoldComps returns real eBay sold listings — completed sales, not active listings or estimates — from a single API call.

One keyword search returns up to 240 sold items, each as clean JSON with:

• Sold price, shipping, and currency
• Condition and sale date
• Seller info and a direct item URL

Most tools lock this data behind a dashboard or require an approved eBay developer account. SoldComps hands it back as a simple authenticated GET request you can integrate in minutes — across 8 eBay marketplaces.

Feedvisor's answer:

Feedvisor is an agentic commerce platform built for brands and large sellers operating on Amazon, Walmart, and other leading marketplaces. Unlike traditional tools that optimize advertising, pricing, inventory, or analytics in isolation, Feedvisor connects every critical business signal into a single AI-powered decision engine.

Connected Commerce Intelligence Most marketplace technologies focus on one function at a time. Feedvisor connects advertising, pricing, inventory, demand, promotions, and competitive intelligence so every decision is informed by the full context of the business. This eliminates the disconnects that occur when separate teams and tools optimize toward competing objectives.

Agentic AI That Acts, Not Just Reports Feedvisor goes beyond dashboards and recommendations. Its AI continuously evaluates marketplace conditions and business performance, coordinating decisions across advertising, pricing, and commerce operations in real time. The platform helps brands respond faster to changing demand, competitive shifts, inventory constraints, and margin pressures.

Built Around Business Performance Most platforms optimize for channel-specific metrics such as ROAS, ACoS, clicks, or impressions. Feedvisor optimizes against broader business outcomes, including profit, contribution margin, growth, inventory efficiency, and TACoS. This ensures that marketplace decisions support long-term business performance rather than isolated campaign results.

Advertising Engineered for Profitability Feedvisor's advertising capabilities are informed by business signals that traditional ad platforms cannot see. Bidding, budget allocation, targeting, and optimization decisions can incorporate pricing strategy, inventory position, competitive dynamics, and demand trends to maximize profitable growth rather than simply improving advertising efficiency metrics.

Real-Time Competitive Intelligence Feedvisor continuously monitors changes in the competitive landscape, including pricing movements, promotional activity, search visibility, and demand shifts. These insights are connected directly to advertising and pricing decisions, allowing brands to respond proactively rather than react after performance has already changed.

Unified Marketplace Optimization Instead of managing multiple disconnected systems, brands operate through a single platform that coordinates decisions across the entire marketplace business. By aligning every lever to the same profit model, Feedvisor helps brands scale more efficiently, protect margins, and uncover new growth opportunities.

Expert Guidance and Strategic Partnership Technology alone is rarely enough. Feedvisor combines AI-powered automation with marketplace expertise, strategic guidance, and customer success support to help brands maximize the value of the platform and accelerate business growth.

The Difference: Most marketplace platforms optimize campaigns. Feedvisor optimizes businesses. By connecting every signal and coordinating every decision, Feedvisor turns marketplaces into a lever for profitable growth.

SoldComps's answer

SoldComps started from a simple, recurring frustration: eBay is the best source of real sold-price data, but actually getting that data is painful.

eBay's own API heavily restricts access to sold listings and gates it behind an approval process, and pulling comps by hand is slow and doesn't scale.

So SoldComps collapses all of that into one clean API call — pass a keyword, get back up to 240 completed sales as structured JSON — so resellers and developers get the pricing data they need without wrestling eBay's API or scraping it themselves.

SoldComps's answer

SoldComps is built in TypeScript — a Hono API backed by PostgreSQL, with a React web app. Billing runs on Stripe.

SoldComps's answer

SoldComps is used across its core audiences rather than a few big-name accounts:

• Resellers and flippers pricing inventory before they buy
• Developers adding eBay sold-price data to their apps
• Market researchers analyzing demand and pricing trends
• Estate-sale and liquidation pros pricing large lots fast
