How much does a block cost on spare tokens?

R$5 for 5 hours of GROK 4.6 High Fast. One-step Pix. No subscription. No second till.

How do I get in after I pay?

The block code (wdtsot-XXXX) is the login on the web and over SSH. The same ?code= invites a friend.

What is a skill on the shelf?

A short manifesto and the CLI allowlist: cursor, codex, claude, antigravity, metamuse. Pix stays R$5 / 5h. No second till.

What do the short agents do?

Short post, shelf copy and invite hook. They open in the same chat. The till stays R$5 / 5h.

How do I invite a friend?

The same block code. The link is sparetoken.shop/?code=wdtsot-XXXX. 10% (R$0.50) in compute for each friend who closed Pix. Pix at R$5. The first indicator is fuzzy. No email.

How do I sell my tokens?

The same R$5 / 5h card. Ten conta.vc links. The first name on the shelf stays fuzzy. The request is queued for review — live stock is sacred. No second till.

GROK 4.6 High Fast

we deserve to share our tokens.

Five hours. Five reais.

The 5 hours are the time GROK spent thinking — not the tab left open, and not the time you spend typing.

second experience

SSH is one command away.

Use it from the browser. Or don’t. The same model, in an isolated workspace — not an open Linux shell.

—

SSH asks only for the block code (wdtsot-XXXX). If you have not paid yet, it shows an Open Pix. After you pay, the same 5-hour wallet — only model processing time. The same code invites a friend.

why

a notebook, not a pitch.

We work with AI every day. We pay for compute every month.

Some days we use everything. Some days we don’t. Either way, unused capacity disappears.

That feels wasteful.

The experiment has two axes: a marketplace of leftover tokens, and a self-evolving agent that ships every night at 23:30.

We think useful intelligence should be easier to access, skills should be easier to share, and experimentation should be cheap.

we deserve to share.

three short agents — the rest is still coming.

A skill is a short manifesto plus which CLIs may run it: cursor, codex, claude, antigravity, metamuse. Click and the brief drops into the same chat. The till stays R$5 / 5h. No second price.

Built in the open.

The interface, session layer and skill format are designed to be inspectable, forkable and improvable. Code at github.com/sparetoken-shop/sparetoken.

Privacy by default.

We do not sell conversations. We do not show one visitor’s chat to another. There is no hidden prompt harvesting your key. The privacy contract is in the repo: github.com/sparetoken-shop/sparetoken.

Useful intelligence should be easier to access.

Fifty prompts in the browser. Or one SSH command, when you want the long table.

if you read this far

we hope this product does not get in your way.

It is an experiment. Five reais for five hours of a frontier model is cheap — it is almost a gift. The idea is, when there is slack, to share a few tokens with friends. Not to turn this into a business that scales without a limit.

The other axis is the market: one card on the shelf, one reseller name, the same Pix. And the self-evolving agent that, every night, tries to leave the shelf a little less empty.
