Pantheon Access

Public chat is live now. Free tier usage works directly in the app. Paid upgrades use self-serve Stripe checkout and unlock higher quota access.

Start now

  1. Open the Pantheon app.
  2. Use chat immediately or describe what to build.
  3. Open the Access drawer for plans and Stripe checkout.

API access

Programmatic access remains x-api-key based. Free-tier keys and paid upgrades are tracked through Pantheon billing and quota surfaces.

Runtime proof: authenticated billing WAL, quota probes, and checkout receipts remain deterministic and replay-bound.
