How far an AI can go

Live: levels on found listings

  1. Listed It's in the directory.
  2. Readable An AI can read its hours, prices and terms.
  3. Askable An AI can ask and get an answer.
  4. Bookable / Orderable An AI can book or order.
  5. Payable An AI can pay.

An example. Every yes or partly answer names the door and the date it was checked, from the business's own site.

Who agents can do the most with.

Businesses where an agent can book, order or sign up come above the rest, then the agentic score orders them. Separate from the directory's search order, which nobody can pay to change.

A business is named on leaderboards, and its result page may be indexed, when it is agent-ready (askable or above); others are counted, not named. If your site tells AI systems not to use or train on its content, we don't name you or list you publicly. Each business can hide its own result. Scoring rules: /v1/score-rules.

Ranked by receipts, never by payment.

When a business keeps a booking or delivers an order, its inbox signs a receipt. Receipts build its record.

  • Answering first.

  • Promises kept.

  • No paid places.

Easy to be found.

Your customers deal with you, not us. Their AI talks to you at your own doors, whatever software you use.

Where it stands.

Live

  • Directory of agent-ready businesses: members, and businesses found on their own websites
  • Search it from your AI: MCP, REST or llms.txt
  • Ordered by kept promises under published, versioned rules; nobody can pay to rank
  • Signed hourly pings: an inbox that checks in is answering
  • Receipts: a business's inbox signs every booking, order or refund, and the customer's AI can sign it too
  • A track record on each member's listing: promises kept, broken and still open, over which dates, once enough have closed; the business's own word, with no score, until its customers confirm a fifth of it
  • Open protocol, MIT example network, network-check and SDK 0.2.0
  • Open-source inbox, self-hosted
  • A public page on how our crawler behaves
  • Check any business's website: what an AI agent can do there, and its agentic score by published rules
  • A crawler that reads businesses' own websites for agent doors (MCP, A2A, UCP, ACP, OpenAPI)
  • Businesses found on their own websites in the directory, with doors, levels, what they accept and a source and date on every fact
  • Add, correct, hide or remove your listing from your own AI (register_business, update_business)
