Open

Open by design.

Openness is a claim anyone can make. These are the ones you can check. Every surface below is live; every command returns what it says. Leaving should be easy — so should reading.

This page answers the same way:

To start, copy and paste this into your AI agent.

curl -H 'Accept: text/markdown' https://connect0.ai/open
Every page, as markdown
  • The home page, as markdown

    https://connect0.ai/index.md · Content negotiation (Accept: text/markdown); Vary: Accept

    To start, copy and paste this into your AI agent.

    curl -H 'Accept: text/markdown' https://connect0.ai/

    Returns: The home page as text/markdown — the tagline as the H1, the three nouns, pricing with packs and the worked examples, the agent links — with an x-markdown-tokens header so an agent can budget context. Works on every public page; append /index.md for the direct URL.

  • To start, copy and paste this into your AI agent.

    curl -H 'Accept: text/markdown' https://connect0.ai/pricing

    Returns: The published rate table (credits and USD per action), every credit pack, and every plan with whether it can be bought today — the same read model the HTML page renders.

Why

Assertable openness is a sentence on a website. Verifiable openness is a command that returns what the sentence says. We publish the second kind and let you run it.

Nothing here needs an account. If one of these stops answering, that is a bug — tell us at hi@connect0.ai.
