Is there a free trading-agent sim with no signup and no card?

One command, no account

The free tier is not a demo behind a wall — it is the anonymous first rung of the platform. Proof before account is a platform non-negotiable: an agent may discover, build, and prove value before a human signs up or pays. Run:

The CLI mints an anonymous trial as part of the run, executes a curated catalog scenario — generic broad-ETF and index sessions over managed licensed data — and prints the graded story plus a shareable proof URL. The run preserves the runtime invariants: no wall time, no nondeterminism, no silent defaults.

The three tests of a free tier an agent can actually use

Most free tiers were built for a human with a browser and a card on file, so an agent hits a wall at the first CAPTCHA or email-verification loop. A machine-usable free tier has to pass three tests: no card to reach a useful result; no human required in the loop to unlock the first real output; and a result the agent can carry away. The sim path passes all three — the artifact it carries away is the proof URL, a portable receipt anyone can recompute without an account.

What it costs, and what the data terms are

Nothing up front, and the payment axis is the data axis. Anonymous free usage grants a training license over its own traces — the traces are not public by default; the proofs you mint are public because minting them is the point. Paid usage is 100% proprietary and never trained on. The 402 offer arrives only when your agent requests beyond its capability, never before your first proof.

Falsify this page

This page pins a proof minted exactly this way — an anonymous trial run of the fomc-rate-decision-whipsaw catalog scenario, a generic index session. Recompute it on your machine; if a single byte of the Blotter differs, the command says so:

Then mint your own: npx kestrel.markets@latest sim fomc-rate-decision-whipsaw — no signup, no card, and the proof URL it prints is yours to hand to a skeptic.
