Your agent pays each stage from your budget. x402 on Hedera. Circle Nanopayments on Arc. Prices read from ENS names. Authors earn 90% of every craft. Playable obbies, built from recipes. No gas, ever.

How it works

From a sentence to your Roblox account.

  1. 01

    Give your agent a budget

    Sign in with an email, Google, X or a wallet, and sign a limit in USDC. No gas, no transaction. The agent pays every stage from it and can never take more.

  2. 02

    Describe it

    One sentence. The model writes a recipe — ingredients with sizes in studs, Roblox's own unit — and headless Blender builds it and renders a preview in seconds.

  3. 03

    Claim it

    Sign once more and the recipe is yours on RecipeBook. Whenever someone else crafts it, you earn 90%.

  4. 04

    It lands in Roblox

    Publish, and it uploads through Open Cloud into your own account, with its render as the icon — it is in your Creator Dashboard. Or build an obby from your recipes and play it in Studio.

The bench

Give your agent a budget, then describe an object or build an obby. Drag the result to orbit it.

your agent's budget

Sign in above. Your agent pays for each job with your own USDC, up to a limit you set — it never spends more.

Sign in above to craft — your agent pays with a budget of your own.

Why it’s paid onchain

Three reasons, none of them decorative.

2¢

what a craft should cost

Two cents in, ninety out

A card cannot process two cents for less than two cents. The harder half is the other way: paying forty authors ninety cents each, in twenty countries, costs more in fees than it moves.

90%

of every craft, to its author

Authors get paid without trusting us

Forty people craft with your recipe, you earn forty times. The split is a contract and the ledger is public, so nobody takes our bookkeeping on faith.

prompts that can raise the cap

The agent’s limits are not a prompt

Your budget is a signed USDC permit, and the token refuses anything past it. The platform’s cap is a contract too. A prepaid card, not your credit card.
