Quoin · index #0001

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.

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 turns long-tail commerce into agent-ready inventory. The merchant keeps the existing site; Quoin handles extraction, normalisation, and the rate-limited interface that agents can actually use.

Submit the business URL first. The generated site page becomes the handoff point when the hourly pipeline finishes.

Submit your business URL
  1. 01

    Submit one merchant URL.

    Start with the business URL at /submit. Quoin uses the existing site as the source of truth — no site redesign and no bespoke scraper to commission.

  2. 02

    Quoin extracts and normalises it.

    The extractor fetches the page and normalises inventory, pricing, intake, dispatch, and booking into agent-ready fields. The scraper runs on the hour, so the submitted site stays pending while the pipeline works.

  3. 03

    Get an agent-ready OpenAPI.

    When the site is ready, its generated /sites/<slug> result exposes an OpenAPI 3.1 interface. The request surface is rate-limited for dependable agent traffic, with no per-merchant integration to maintain.

The catalog

A long tail that finally has a spine.

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.
