ChatBox with TopxAI: a custom provider
In ChatBox, add a custom provider in OpenAI API compatible mode with host https://ai.topxea.com and path /v1/chat/completions, then add the model ids.
ChatBox reaches any OpenAI-compatible endpoint through a custom provider.
Setup
Settings → Model Provider → Add Custom Provider.
Name: TopxAI. API Mode: OpenAI API Compatible.
API Host: https://ai.topxea.com. API Path: /v1/chat/completions.
API Key: a TopxAI key on the Auto route.
Model: add claude-sonnet-5, gpt-5.6-sol, grok-4.6, kimi-k3 or GLM-5.3-Abliterated; or fetch the list, which reads /v1/models.
Save and pick the provider in a chat.
Notes
Every text model except Jev is on /v1/chat/completions, including Claude, so one provider is enough. Jev answers typed questions through /v1/systemone and is not a chat model.
If ChatBox offers a separate Anthropic provider with a custom host, https://ai.topxea.com and the same key work there for claude-sonnet-5 and claude-opus-5.
Image generation in ChatBox with this provider uses gpt-image-2.5-sunburst or gpt-image-2.5-flare, billed per image.
If it fails
401: the key is wrong or was pasted with a space. 402: the balance is empty. 403: the model id is not sold here or is not on this key's route. See Common error responses.
The model works in curl but not in the tool: that page lists the usual causes, one per tool.
