Recommended host
Usehttps://api.nano-gpt.com for API-key requests. The direct API host has a higher request size limit and a longer request runtime than https://nano-gpt.com, so it is the better choice for large attachments, long conversations, and model calls that take time to finish. Batch file uploads also use the direct API host.
The endpoint path and request format stay the same when switching from the website host to the direct API host. For example, replace
https://nano-gpt.com/api/v1/chat/completions with https://api.nano-gpt.com/api/v1/chat/completions.
The direct host’s higher ingress limit does not override the application, model, file-type, or provider limits for a particular endpoint. For authenticated Chat Completions, Responses, and Messages JSON requests, the application body limit is 32 MiB; check endpoint documentation for multipart and file limits. A long-running call also needs a sufficiently long timeout in your HTTP client.
Check GET https://api.nano-gpt.com/api/v1/models?detailed=true for model availability on the direct host. The website and direct API host can have different model catalogs during deployment rollouts; a model listed on one host is not automatically available on the other.
Website flows
Usehttps://nano-gpt.com for the dashboard, creating or managing API keys, browser sign-in, OAuth and device login, and the Management API. Jev Decisions also currently requires the website host; the direct host does not yet serve its dedicated routes or list Jev models. Follow the Accountless x402 API Payments guide for its quote, payment, and callback URLs.
