The book

CREDIT for sale, by how far below a dollar the seller priced it.

Same models, same answers

Requests go to the model you named and nothing else. Answers come back with the provider's own model id on them, so you can check. Prompts are never stored, and requests only route to zero-retention endpoints.

Loading the model list…

List prices are the upstream provider's, read live. The gateway bills each request at exactly the cost the upstream reports, in CREDIT. The saving is the discount you bought the CREDIT at.

Where the discount comes from

People stake SPARE. Every hour the program pays them CREDIT out of real USDC that came in. Some of them would rather have cash, so they sell it on the book below a dollar. You buy it there.

One hour, in round numbers

An example to show the arithmetic, not a forecast.

She sells at 25% off for$7.50

The buyer pays $7.50 plus the 5% fee, $0.38, and gets $10 of model usage. The $10 in the bank pays for the model calls when the CREDIT is used.

CREDIT is only minted against USDC the program already holds. The admin can change the fee (capped at 10%) and where fees go. It cannot move the bank or mint.

Questions

What am I buying?

CREDIT, a Solana token worth one dollar of model usage through Spare's gateway. Hold it, send it, or activate it. Activating burns it and adds the same dollars to your API balance.

Am I getting the real model?

Yes. The gateway forwards your request upstream with the model you named and does not touch the messages. The answer carries the provider's own model name and id.

Do you store prompts?

No. The ledger keeps the model, token counts, cost and timing of each request. Prompts and answers pass through and are not written anywhere, and requests only go to zero-retention endpoints.

What does the fee cover?

5% of what you pay sellers on the book, shown before you sign. Usage itself is billed at the upstream's own price with nothing added.

Why would anyone sell a dollar for 75 cents?

Stakers get CREDIT for free every hour. Most of them do not run models, so cash now beats usage later. The book lets each one pick their price.

Can I get my money back?

CREDIT you have not activated can be sold on the book like anyone else's. Activated balance is spent on usage and is not redeemable for cash.
