Model access
Being in the catalog and being callable by your account are two different things.
What decides availability
- The catalog. The model exists, has an approved price and a usable route.
- Your account. During the invite-only rollout an account may be limited to a subset.
- The key. An individual key can be restricted further still.
GET /v1/models with a specific key returns the result of all three
— it is the authoritative answer for that key.
What refusal looks like
404 model_not_found— no such model.403 model_not_allowed— the model exists but this account or key may not call it.
Not yet available is not an error
Models shown as "Not yet available" in Models are on
the launch plan but not callable. They are listed so you can see what is coming;
calling one returns a clear refusal rather than a substitute.
No substitution
Astrodyne runs the model you name. It does not silently route your request to a different or cheaper model.
