ROUTEXOR, LLM selector

Your agents run 24/7. Your router should think before it spends.

The agent control plane for autonomous AI workloads. BYOK-only, agent-native, managed. Drop-in for the OpenAI SDK and for Claude Code. More than three hundred models across fourteen providers, refreshed from provider catalogs every minute.

Credit gateways monetize the float. ROUTEXOR never touches it.

A credit-based gateway holds the customer’s prepaid balance and takes a percentage of every top-up, so its revenue grows with the customer’s token spend. Agent workloads run 24/7, and a percentage of a bill that never sleeps compounds into real money.

ROUTEXOR is the inverse. The customer holds the keys, provider invoices land in the customer’s own accounts at list price, and ROUTEXOR charges 2.2 percent of usage or a flat $99 a month with zero markup. The float never touches us.

Fig. 1   ROUTEXOR’s fee at five spend levels

Same tokens. One added line, and on the flat plan it does not move.

Read across. The provider bills the tokens at list price in the customer’s own account; the ROUTEXOR fee is the only line we add. Below $4,500 a month of model spend Starter is cheaper. Above it, the flat plan wins.

Pro, $99 a month

Monthly cap per key, daily cap per task profile, checked before dispatch

List-price arithmetic from the plan page at routexor.com, checked September 23, 2026. Dollar rows are the ROUTEXOR fee only; provider charges apply on top, in the customer’s own accounts. Not a savings estimate for any account.

Three edges in production. One on the roadmap.

Three of these are engineering, and they are in production at routexor.com today. The fourth, CORTEX memory at the routing layer, is planned and not built.

1

BYOK only

The customer holds the provider keys. Provider invoices land in the customer’s own accounts. Keys are encrypted in a per-user envelope, audited, and rotatable. On the flat plan ROUTEXOR has no usage-linked revenue at any scale, so nothing in the business needs the customer to spend more.

2

The job is the unit of routing

Task profiles are first-class objects, not settings on a key. Each profile carries its own model, fallback chain and daily dollar cap, and every call is checked against its caps before dispatch. Cumulative budgets per agent run are built and switched off until design partners test them.

3

One hop, on your key

A multi-step agent chain pays the gateway’s overhead on every hop. ROUTEXOR is a single hop on the customer’s own key with no credit ledger in the path. We do not quote a competitor’s latency number, and we will not quote our own until it is measured and published.

4

CORTEX memory, on the roadmap

CORTEX, ATERNA’s memory engine, is not wired into routing today. Routing on what an agent already remembers is a design for after the round, and it ships only once it is measured.

Four tiers. Two ways to pay. Zero token markup.

Pay 2.2 percent of usage as you go, or a flat $99 a month that never moves with tokens. Either way the bill from your model providers is yours, in your own accounts, at their list price.
