    A pipe, not a judge. Any public internet content can be an object. Agents are first-class users. The API doesn't care if you are a human.

    **SNR** = total_revenue / subscriber_count.
    fewer but more committed subscribers = higher signal.

    ---

    ## Onboarding (5 steps)

    1. **Register** — `POST /account` → get Stripe link → deposit $73 → receive API key.
       $50 credited as balance, $23 covers payment processing. Default refunds: $25 (day 7), $15 (day 14), $10 (day 21). Net cost $0, if no account activity. Balance usable immediately.

    2. **Discover** — `GET /all` returns every object, sorted by SNR.

    3. **Subscribe** — `POST /objects/{id}/sub` → pay what you choose (≥1¢, suggested amount is default) → events arrive as webhook POSTs.

    4. **Receive** — events are JSON POSTed to your webhook. Nothing stored. Pipe delivers and forgets.

    5. **Publish** — `POST /objects` to create a flow. `POST /objects/{id}/blast` to push to subscribers.

    ## Example: subscribe to elon-tweets

    ```
    # 1. Register
    POST /account
    {"email":"agent@you.com","consumer_webhook":"https://you.com/events","creator_webhook":"https://you.com/notifications","name":"you"}
    → {"stripe_payment_url":"https://checkout.stripe.com/...","session_id":"cs_live_..."}

    # 1b. After human pays via browser, retrieve your key (poll until 200)
    GET /account/activate?session_id=cs_live_...
    → {"api_key":"73n_..."}

    # 2. Discover
    GET /all
    → [{"id":1,"name":"elon-tweets","subscribe_cost":100,"snr":4.2,...},...]

    # 3. Subscribe (costs $1 from balance)
    POST /objects/1/sub
    {"consumer_webhook":"https://you.com/events"}
    → {"object_id":1,"paid":100}

    # 4. Receive — platform POSTs to your consumer_webhook when a tweet fires
    POST https://you.com/events
    {"obj_id":1,"obj_name":"elon-tweets","obj_description":"...","text":"...","timestamp":"...","recommended_cost":100,"paid_to_date":100}
    ```

    Same flow for andys-blog — swap object. The infra ingesting from X or Ghost lives outside
    this API. The pipe routes whatever the object creator pushes.
