Long-tail commerce,
structured for AI agents.

Long-tail commerce, structured for AI agents. One URL, one OpenAPI — turn the fragmented small-business web into agent-ready inventory. Quoin turns one merchant URL into a rate-limited OpenAPI plus webhook triggers — so the boutique hotel, the regional equipment rental shop, and the niche specialty provider become agent-ready, without bespoke scrapers or one-off integrations.

Already shipping with merchants in hospitality, field services, and specialty commerce.

The position

The fragmented SMB web is a $4T black-box
for every AI agent.

Hundreds of thousands of small businesses run their commerce on bespoke, hand-coded websites — boutique hotels, regional equipment rental shops, independent tour operators. Each one is a different schema, a different rate-limit, a different scraper. Today’s agentic economy can’t transact with any of them.

What the long tail looks like today
Every “no integration available” is a missed transaction.
Web presenceHand-coded HTML, regional CMS, WordPress, Wix, Squarespace.
BookingsForms, email, occasional Calendly — none queryable.
PricingHidden behind calls, PDFs, or third-party widgets.
Modern coverageNone — not Stripe Atlas, not Stripe Terminal, not Plaid.

How it works

Three steps. One URL to a queryable transaction.

Quoin doesn’t require the merchant to redesign anything — and doesn’t require the agent to write a per-merchant scraper. We handle the regulatory and rate-limiting heavy-lifting so neither side has to.

  1. 01

    One URL in.

    A merchant pastes a single link from a lightweight dashboard. Skipping three days of integration for one Yelp-ready shop.

  2. 02

    One schema out.

    Lists, pricing, intake, dispatch, and booking are extracted, cleaned, and normalized into a rate-limited OpenAPI — no scrape farm in the middle.

  3. 03

    One catalog for agents.

    Quoin exposes the long tail as one queryable marketplace. Agents discover, transact, and pay without writing bespoke scrapers per merchant.

The catalog

A long tail that finally has a spine.

We index the SMB web by vertical, then by intent — booking, quoting, scheduling, intake, dispatch. Every merchant in the catalog carries the same surface area an AI agent expects.

Who it’s for

Built for the developer on one side,
the merchant on the other.

For AI-agent developers

One OpenAPI for the whole long tail.

  • A single query returns thousands of mid-market merchants — bookable, quotable, schedulable, no per-site parser.
  • Rate-limit guarantees and webhook triggers are calibrated for agent execution, so the heavy lifting is already done.
  • Usage is metered, transparent, and recurring — so merchants trust it and agents get a stable surface area.
For small businesses

Get discovered without rewriting your site.

  • You don’t need to redesign your landing page — your existing site is the source of truth.
  • Submit a single URL and we extract structured data without domain expertise so AI agents can transact with you.
  • A transparent usage meter turns what was one-off scraping into a metered, recurring revenue lane on your side too.
