Is Nexa a marketplace or a payment processor?

Both, plus the tools around them. Shoppers experience Nexa as a marketplace, while sellers also get a real merchant account, card processing, payouts, and reporting through the same platform.

Do I need a membership to shop on Nexa?

No. Browsing and buying are open to everyone, and guest checkout is supported. A free account is only needed for rewards, order history, and saved try-on looks.

How do sellers get paid?

Card payments are authorized at checkout, captured on fulfillment, settled in batches, and funded to the merchant's own bank account on a predictable schedule. Payout status and history are visible in the seller dashboard.

What can the Nexa AI assistant do?

For shoppers it searches the live catalog, quotes current prices, and can suggest cart additions with confirmation. For sellers it explains revenue and margin, flags inventory and reorder needs, drafts listings, and surfaces growth opportunities.

Can I bring my existing store to Nexa?

Yes. Products, images, variants, and inventory can be imported from a connected store, uploaded as supplier archives or spreadsheets, or synced for dropship inventory with reorder logic.

How does Nexa handle auctions?

Sellers can schedule auctions for any product with real-time bidding and automatic proxy bidding up to a bidder's maximum. An AI wizard helps research comparable sales and set opening prices and increments.

What are Nexa rewards?

Qualifying purchases accrue cash back to the shopper's account automatically, with the amount set by the reward tier that applies. The estimated reward is shown before the order is placed.

How is payment data protected?

Card data is encrypted in transit and tokenized by the payment gateway, and the application never stores full card numbers. Account data is protected with row-level access controls and role-based permissions.

How can AI assistants access Nexa's information?

Nexa publishes this ecosystem index, a Knowledge Center of reference articles, structured data on product and content pages, an XML sitemap, a shopping product feed, and a plain-text /llms.txt discovery file.

It combines an online marketplace, real merchant accounts, card payment processing, AI shopping and business assistants, storefront building, live and auction selling, cash-back rewards, and developer integrations into one connected platform. This page summarizes the entire ecosystem in one place so people and AI assistants can understand what Nexa is, who it serves, and how the pieces fit together.

At a glance

What it is: An AI financial operating system: a single platform where a business can list products, sell them, accept card payments, get funded, and understand its numbers, without stitching together separate tools.
Who it serves: Shoppers who want to find real products at real prices with AI help, independent sellers and small brands who need a storefront plus a merchant account, and larger merchants who need catalog imports, feeds, and reporting.
What it replaces: A typical stack of marketplace listing tools, a website builder, a separate payment gateway, spreadsheet-based reporting, and manual inventory or reorder tracking.
How access works: Browsing and buying are open to everyone with no membership. Selling requires an application and merchant onboarding. Rewards and saved looks require a free account.

The Nexa AI Marketplace

The marketplace is the public storefront of the ecosystem. Shoppers browse curated categories, deals, bundles, and individual seller stores, or describe what they want in plain language and let the assistant find matching products from the live catalog. Listings carry real prices, real inventory, and real variant photography, including per-color and per-size images where the seller provides them.

Fashion and apparel listings can include virtual try-on, which lets a shopper take or upload a photo and preview how an item looks before buying. Saved results live in a personal looks gallery. Every product page is individually addressable and shareable, and product data is published in structured form so search engines and shopping surfaces can read it.

Merchant services and payment processing

Sellers on Nexa are not sub-accounts on a shared processor balance. Each approved merchant gets its own merchant account and card processing, so funds settle to the merchant's own bank account on a predictable schedule. Underwriting, onboarding steps, and account status are tracked through a guided merchant onboarding pipeline.

Card payments move through the standard lifecycle: authorization at checkout, capture when the order is fulfilled, settlement in batches, and funding to the bank. Refunds, disputes, and recurring billing are handled through the same gateway. Card data is tokenized in transit and never stored in application code or the app database.

AI assistants for shoppers and sellers

A shopping assistant is available across the marketplace. It searches the live product catalog, quotes current prices, and can suggest cart additions, always with explicit confirmation before anything is added. It is grounded in real platform data rather than generic web results, so its answers reflect what is actually in stock.

Sellers get a parallel assistant inside their dashboards. It explains revenue and margin after processing costs and refunds, flags inventory that needs reordering, drafts listings and descriptions, and surfaces growth opportunities as readable insights rather than raw charts.

Storefronts and the AI store builder

Every seller can run one or more branded storefronts with their own logo, colors, hero media, and category structure, each reachable at a short, shareable URL. Storefronts are built conversationally: describe the brand and the products, and the builder scaffolds the layout, sections, and starting content, with a live preview while you refine it.

Storefronts support specialized templates, including catering and menu ordering for food businesses and editorial layouts for fashion brands. Owners can invite staff and grant scoped capabilities, such as fulfilling orders or printing shipping labels, without handing over full account access.

Auctions and live selling

Beyond fixed-price listings, Nexa supports scheduled auctions with real-time bidding, proxy or automatic bidding up to a maximum, and urgency indicators as an auction closes. Sellers can schedule auctions for any product, and an AI-assisted wizard helps research comparable sales and set sensible opening prices and increments.

Live selling adds streamed events with chat, product pinning, and reminders so shoppers can be notified before an event starts. Auctions and live events are surfaced on the marketplace homepage alongside standard listings.

Rewards and the Future Fund

Qualifying purchases accrue cash-back rewards to the shopper's account, with the amount determined by the reward tier that applies to the transaction. Rewards accrue automatically at checkout and are visible before the order is placed, so there is nothing to clip or activate.

A portion of platform activity supports the Nexa Future Fund, which turns ordinary shopping into student and community support. The impact program pages explain how contributions are calculated and where they go.

Integrations, feeds, and developer access

Merchants can connect an existing store and import products, images, variants, and inventory rather than re-entering a catalog by hand. Supplier archives and spreadsheets can be uploaded directly, and dropship inventory can be synced with reorder logic so listings stay accurate.

Outbound, Nexa publishes product feeds for shopping channels, structured product data on every listing page, a sitemap of all indexable URLs, and this machine-readable index plus an llms.txt discovery file so AI assistants can find and cite the right pages.

How AI assistants can read and query Nexa

Nexa is built to be read by machines as well as people. Every public page ships structured data, and there are dedicated endpoints an assistant can fetch directly instead of scraping HTML. AI crawlers from OpenAI, Anthropic, Perplexity, Google, and Apple are explicitly allowed in the site's robots rules.

/llms.txt: A plain-text index of every public page on the marketplace, with a one-line description of each, at https://shop.nexaofs.com/llms.txt.
/llms-full.txt: The complete text of every knowledge page in one file, at https://shop.nexaofs.com/llms-full.txt, so an assistant can load the whole reference in a single fetch.
MCP server: A Model Context Protocol endpoint at https://shop.nexaofs.com/mcp that lets AI agents query live products, stores, and catalog data instead of relying on cached page text.
Structured data: Schema.org JSON-LD on every page: Product and Offer data with live price and availability on listings, Store data on storefronts, plus Organization, WebSite, BreadcrumbList, and FAQPage markup.
Feeds and sitemaps: Product feeds for shopping channels and XML sitemaps covering every indexable page, storefront, and product listing.

Step-by-step setup instructions for connecting ChatGPT, Claude, and Claude Code to the Nexa MCP server are published at https://shop.nexaofs.com/connect.
