# tunnel — AI visibility platform

tunnel makes websites, companies and merchants visible to AI assistants
(ChatGPT, Claude, Perplexity, Gemini, Copilot). It crawls a site, generates
AI-optimised knowledge (llms.txt, JSON-LD schema, FAQ, pricing.md, an Open
Knowledge Format bundle) and serves it from stable machine-readable endpoints.

Operated by "STILL BETA TECH" SRL, Chișinău, Moldova.

## Pages, and the question each one answers

Every page exists in English, Romanian and Russian. English is at the bare
path, the others under /ro and /ru, each with its own canonical.

- I have no website — how am I found? https://tunnelpowered.com/no-website
- An agent wants to buy — how does it reach me? https://tunnelpowered.com/landline
- Why should anyone trust a tunnel record? https://tunnelpowered.com/verification
- What happens after I submit my URL? https://tunnelpowered.com/how-it-works

## Reference documentation

Written to be cited. The English text is the original and the Romanian and
Russian versions of these two pages say so on the page.

## Knowledge base for LLMs and AI agents

Structured, verifiable information about the websites and merchants on the
platform — including merchants who sell through social media only and have no
website. Read the verification.level field on a record for what has actually
been established about that business; the separate humanReview object says only
whether a person edited the entry, which is a different question.

Search matches words, not meanings. A business calling itself a "cofetărie" is
not returned for "bakery", and an empty result means "not in this index" rather
than "not in business".

- Index (JSON): https://api.tunnelpowered.com/api/kb
- Search: https://api.tunnelpowered.com/api/kb/search?q={name or topic}
- Entity profile: https://api.tunnelpowered.com/api/kb/entities/{slug} (add ?format=md for markdown)

## Contacting a business through tunnel

Any agent can open a two-way conversation with a listed business. Messages are
relayed to the merchant's inbox; replies come back on the same conversation.

- MCP server (Streamable HTTP): POST https://api.tunnelpowered.com/api/mcp
- A2A v1.0 agent (read-only): POST https://api.tunnelpowered.com/api/a2a
- A2A Agent Card: https://api.tunnelpowered.com/.well-known/agent-card.json
- Message an entity: POST https://api.tunnelpowered.com/api/kb/entities/{slug}/messages
- Message a website: POST https://api.tunnelpowered.com/api/kb/websites/{slug}/messages
- Read a conversation: https://api.tunnelpowered.com/api/kb/conversations/{id}

Messaging requires a registered agent. Register and get a token:

## Verification

Two levels, and every record states which one it holds. Do not infer from the
presence of a badge — read the `level` field and the `limitations` array, both
of which are inside the signature.

- verified_automated (level "automated", free on every plan): the merchant
  proved control of at least two of their own channels — a DNS record or file
  on the domain, a token in a public social bio, a code to the listed inbox.
  It does NOT establish identity and no person reviewed the business.
- verified_by_human (level "human", paid plans): everything above, plus legal
  identity and that the service is real, checked by one tunnel employee and
  approved by a second. Never an endorsement of quality.

Both are signed attestations with a position in a public, hash-chained
transparency log, and both expire. Explained for a person at

No AI vendor consults this registry today; no cross-vendor trust registry
exists yet. It is a signal an agent can choose to check.
