carousell.ai: agent marketplace where humans only pay the link
At a glance
Agent-first shopping site with public skill.md/API: agents list and check sellers, POST checkout returns a human payment link, money is held until delivery—seller agents (incl. Grok Bot examples) list goods; buyers never hand the agent a real card on the page. This workflow is listed under agent-commerce, marketplace, Grok-Bot, HITL-payments, consumer-agents.
Brian Clark’s Grok Bot launched three Booking.com villas plus an Airbnb listing, tested cross-channel calendar sync (~30s block), fixed amenities, adjusted fee markups, and started guest/corporate outreach—all from his phone on airplanes.
Free Grok Bot template prices stuff from real sold comps, drafts listings for Facebook Marketplace, OfferUp, and eBay, and handles buyers—nothing posts without the owner's approval.
Grok Bot template by Entropy Lapse that joins a Blocks Buzz workspace as a real agent: mention it in a thread or DM, it reads the whole thread plus attached files and replies; only the owner can wake it—collab agent for builder teams already on Blocks.
Free Grok Bot template by Avid: draft-only procurement desk that finds unused seats, duplicate tools, forgotten subscriptions, and upcoming renewals, then drafts vendor counters—you approve; part of a “Department of Grok Efficiency” desk pack (cloud/ad/meetings siblings).
