FAQ
Answers to common questions about Nebula Block accounts, limits, billing, compute, and data residency.
Getting started
Can I use the platform for free? You can create an account for free, but the free tier (Tier 1) has a per-model daily request cap of 0 on most of the catalog, so in practice you need credit to call models. A $5 deposit moves you to Tier 2 and opens things up. See Tiers and Rate Limits.
Which API do I call? Two base URLs, one API key for both. Use https://inference.nebulablock.com/v1 to run models, and https://api.nebulablock.com/api/v1 to manage instances, storage, keys, and billing. See the API Reference.
Can I use the OpenAI SDK? Yes. The Inference API implements the OpenAI surface — set base_url to https://inference.nebulablock.com/v1 and your Nebula Block key as api_key. See the Quickstart.
How do I know which models are available? Call GET /v1/models for the live list, or browse the Model Catalog.
Limits and errors
Why am I getting a 429? You have hit one of three limits: requests per minute, tokens per minute, or requests per day — either account-wide or for that specific model. The message says which. Per-day counters reset at 00:00 UTC. Your current limits are under Limits in the console.
A model works for someone else but returns 429 for me. Daily caps are set per model and per tier, so the same model can be available at one tier and capped at zero on another. Upgrading your tier is what changes it.
Why am I getting a 402? Your credit balance cannot cover the request. This is returned up front for priced jobs such as video generation, so nothing is queued or charged.
Compute
What do I need to rent a GPU? Tier 3, reached with a $10 deposit, plus an SSH key on your account. See the GPU Cloud Quickstart.
What happens if I run out of credit while an instance is running? Instances are deleted automatically when the balance is exhausted. Turn on Auto-Pay for anything you cannot afford to lose — see Billing.
Am I billed for a stopped instance? Yes. Instances are billed for as long as they exist, powered on or not. Terminate what you are done with.
Data and accounts
Where is my data processed? Models marked 🇨🇦 in the Model Catalog are hosted in Canada, and GPU capacity is available in Canada, the US, Finland, France, and Norway. See Sovereign AI Compute and the Data Policy.
Can I share resources with my team? Yes — Teams give you shared billing, per-member roles, and team API keys. That is the supported route; the same payment card cannot be used on two separate accounts.
