Live demo

Run a session. Get one receipt.

An autonomous agent rarely makes one call — it plans, checks its own state, and acts. Metrecept doesn’t just meter each crossing; it closes the whole session into a single signed receipt. Run three turns below, then verify the aggregate yourself — no Metrecept code required.

  • Turn 2 replays turn 1 from cache — the pipe, doing its job.
  • Every turn is billed and ledgered live; nothing is staged to make the demo look better than production.
  • Closing the session mints one Ed25519 JWS (kind: session) over the whole run — decode and verify it right on this page (see The black box).

  1. 1

    Turn 1 — plans the next step

    “Check today's spend total before I draft anything.”

    —
  2. 2

    Turn 2 — re-checks its own plan

    “Check today's spend total before I draft anything.”

    —
  3. 3

    Turn 3 — drafts the update

    “Draft a two-line status update: spend is on track, continuing the task.”
