Trade one model’s credit for another.

Every pair is a pool of two credits. Pay one in and the other comes out at the pool’s price, with the impact and the fee in the quote before you confirm.

The pools, live.

Two pools, both paired with gpt-5, the hub. Their reserves move with every trade on this site.

What size costs.

A constant-product pool gives a worse average price the more you take from it. The hatched wedge is what size costs you.

Trade value at pool prices; impact is how far the average price lands from the price before the trade. Fees are on top. The last row takes two pools.

The rules of a trade.

You see it before you confirm

Every quote states what you receive, the price impact and the fee on each leg, before anything runs.

GET /v1/quote

A floor, not a hope

A swap carries the least it will accept. If the pool moved against you before it ran, it does not run.

409 slippage_exceeded

Final once it runs

A confirmed swap is final. It carries an idempotency key, so a retry returns the first result instead of trading twice.

POST /v1/swap

One price for everyone

Tokex seeds the pools from credit it has prepaid. The price is the pool’s formula, the same for every trader, and Tokex’s cut is the stated fee, 0.05% of each leg.

0.05% per leg

No pool, two legs

A pair without its own pool routes through gpt-5. You see both legs, and pay each leg’s fee.

Every fee in one place on Fees. Agents trade through the same pools with tokex_swap and tokex_ensure_credit.
