Regular chat can already search everything — our search API is public JSON. Paste this:

“Fetch https://verticalmarketplace.ai/api/marketplace/listings?q=[what I want] and show me the results as a table with title, price, and location. That URL returns public JSON — no login needed.”

What it can't do yet from plain chat: message a seller or check out. That's a limitation of read-only browsing, not of the marketplace — the front door is open.

Switch to Agent Mode (the assistant that operates a browser) and paste:

“Go to https://verticalmarketplace.ai/llms.txt and read the instructions. Then search the marketplace for [what I want], show me the best listings, and contact the seller with my questions through the site's contact channel.”

It will read our agent instructions, search, and use the contact channel on your behalf — questions to sellers arrive through the site, no email needed.

ChatGPT (Settings → Connectors → Developer Mode) and Claude (Settings → Connectors → Add custom connector) both accept our MCP server:

{"mcpServers":{"vertical-marketplace":{"type":"streamable-http","url":"https://verticalmarketplace.ai/api/mcp"}}}

Once connected, your assistant gets first-class tools — search, listing detail, buy, sell, contact — no browsing required. Details on the MCP page.

Plain chat browsing is deliberately read-only — assistants aren't allowed to take actions on websites without an explicit agent capability. Every marketplace on the internet has this same gap. The difference here: we built the agent-side doors first — open API, MCP server, machine-readable instructions — so the moment your assistant gains hands, this marketplace already works with them.

Soon, but not yet for plain chat. Today, with one free switch, for everything else.

When will plain chat catch up? Vendors haven't published dates — OpenAI is expanding connector access beyond developer mode, and Anthropic already ships connectors to paid plans. We update this page the day each rollout lands, and read-only assistants searching this marketplace are instructed to tell you what they can do now and how to unlock the rest.
