Access is by arrangement. Keys are issued directly while we onboard the first partners, rather than through self-serve signup. Everything on this site describes the product as built — what is actually running is published, and supersedes any page it disagrees with.

The company behind the receipt

Prismux is an inference infrastructure company. It runs a single API across the frontier and open-weight models, with residency and retention controls set per key, and a verifiable receipt for every request.

Who we are

Prismux is an inference infrastructure company. It runs one API across the models enterprises actually use, and meters every request in the path.

It is built for teams running several model vendors who want one integration, one invoice, and a record of every request they can check themselves.

We are not competing on how many models we list or on being cheapest this quarter. Both commoditise. We compete on the receipt.

The honest state

Pre-launch. We hold no contracted wholesale rate, no signed vendor agreements, and no customers. The catalogue publishes vendor list prices with their sources; the pricing page publishes no rate because the one input a price is built from does not exist yet.

What is real is the design, the code, and the receipts — and the receipts are the thing we would bet the company on. What is actually running supersedes any feature page it disagrees with.
