Harpy Paper — all-access sandbox

Every module unlocked, paper mode only. The preview installer for operators deciding which of the live surfaces to commit to.

Paper is the installer we recommend for the first week. It unlocks every module — Trade, Crypto, Polymarket, Kalshi, Horses, Greyhounds — in paper mode simultaneously. No broker keys required for most modules; real prices are fetched from public endpoints and fills are simulated.

Why ship a sandbox

We sell each live installer as a leased 31-day tool, which means a buyer is committing real money to a single surface before seeing the output. That’s too cold a first touch for most people. Paper lets you run the entire terminal end-to-end, watch a couple of scan cycles, read the journal, look at the rejected-candidates list, and decide which of the six live installers is worth the conviction.

What’s different

  • All seven market tabs are visible in the dashboard at once.
  • Scheduled tasks are all seven: Monitor, Scan, Crypto, Polymarket, Kalshi, Horses, Greyhounds, Rollover.
  • No broker keys required by the wizard — the Anthropic API key (or Claude Code subscription sign-in) is all that’s needed.
  • No live-trading path. Flipping a mode toggle in Paper does nothing; the installer is compiled without the live executors linked.

When to move on

Once you’ve watched a module produce targets across a full cadence cycle — ideally a week — and the output rubric resonates, switch to the live installer for that market. The data on disk is portable; you can copy your operator journal and trade history across installers.

Paper is free to trial during the open invite batch and leases for 31 days like every other module.
