Sovereign route — served only inside the KingdomInternational route — frontier models, served abroad
Sovereign route · KSA onlyLive

Served in the Kingdom. Nowhere else.

Every request on this route is answered by an endpoint inside the Kingdom of Saudi Arabia — a Sigmix GPU or an in-Kingdom partner. If none can answer, the request fails. It is never sent abroad instead.

Base URL
https://inference.sigmix.sa/ksa-sovereign-route-only/v1

Authenticate with a key that starts sgx-ksa-. Keys for the other route are refused here.

Three locks on the border

The key

A sovereign key (sgx-ksa-…) works on this path and is refused on the international one. It cannot be re-scoped.

The path

This base URL is its own route in the gateway. No header, parameter or body field can move a request to the other route.

The database

The routing table cannot store a link from a sovereign model to an endpoint outside the Kingdom: the database refuses the row.

Every endpoint on this route is confirmed as in-Kingdom by a named operator when it is added, and that confirmation is kept in the audit log. Prompts and outputs are not stored — only request metadata.

Your first call

Any OpenAI SDK works: set the base URL and the key. The samples use the first chat model published on this route.

curl https://inference.sigmix.sa/ksa-sovereign-route-only/v1/chat/completions \
  -H "Authorization: Bearer $SIGMIX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"cohere.command-a-03-2025","messages":[{"role":"user","content":"Summarise Vision 2030 in one sentence."}]}'

Streaming

Add stream: true for server-sent events. Streaming needs an available balance of at least $20.00.

Rules that apply on every request

Billing

The most a request could cost is reserved before it runs and settled to the real usage after. A non-streamed response carries x-sigmix-charge-usd with the exact charge; a stream's charge appears on the Usage page when it ends.

Streaming

Available on chat models above an available balance of $20.00. A stream you close early is charged only for what was generated.

Limits

60 requests a minute per key unless you set your own; per-key concurrency and spend caps are yours to set in the console.

Every error has a code that says whose it is. The full list
