Key format & how to get one
Prefix: nvapi- Example: nvapi-abc123... NVIDIA API keys start with nvapi- and work at integrate.api.nvidia.com. The /v1/models list is public, so a real test posts a tiny chat request. 1. Sign in at https://build.nvidia.com 2. Pick a model and click 'Get API Key' (or open your account API keys) 3. Copy the key (starts with nvapi-)
How to test
- Copy your key from build.nvidia.com (it starts with nvapi-).
- Paste it into the cURL command above and run it in your terminal.
- A 200 response with a completion means the key works; a 401 means it's invalid.
Common errors
| Cause | Fix |
|---|---|
| Invalid, revoked, or mistyped key. | Create a new key at build.nvidia.com and paste it into the command above. |
| Key lacks access to the requested model. | Pick a model your account can access, or request access on build.nvidia.com. |
| Rate limit exceeded. | Wait a few seconds and retry. |
Cannot test this key from your browser
This provider blocks in-browser requests or requires a server-side secret. Test it from a terminal instead:
curl -sS https://integrate.api.nvidia.com/v1/chat/completions -H 'Authorization: Bearer {{KEY}}' -H 'Content-Type: application/json' -d '{"model":"meta/llama-3.1-8b-instruct","messages":[{"role":"user","content":"hi"}],"max_tokens":1}'Related tools
