Use https://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. The website host rejects request bodies over about 4.5 MB with HTTP 413. 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. https://nano-gpt.com/api/v1 keeps working, with the lower limits above. 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.

IPv6-only clients

api.nano-gpt.com has an IPv4 address only. A client with no IPv4 route can’t reach it directly, so use https://nano-gpt.com with the same paths instead.

Website flows

These routes stay on https://nano-gpt.com. The direct API host answers them with 404 route_not_available, or 403 for browser sign-in:
  • The dashboard, browser sign-in, OAuth and device login, including /api/cli-login/* and /api/v1/auth/keys
  • The Management API and Teams routes under /api/teams
  • Account routes under /api/user, including saved provider keys
  • Invitations, under /api/invitations/create
  • USD deposits and Daimo deposits. For simplicity, the crypto deposit guide keeps every /api/transaction example here too
  • Price helpers: /api/get-nano-price and /api/get-fiat-prices
