Make a request
Use curl or your favourite SDK — only the base URL changes:
curl https://api.kumo.cloud/v1/chat/completions \
-H "Authorization: Bearer $KUMO_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-5-4",
"messages": [{ "role": "user", "content": "Explain tokens in one line." }]
}'Verify the response
A successful call returns a normal completion JSON object. Look at choices[0].message.content for the reply text and usage for the exact token counts:
{
"id": "chatcmpl-8f2b7e10c9",
"object": "chat.completion",
"model": "claude-sonnet-4-6",
"choices": [
{
"index": 0,
"message": {
"role": "assistant",
"content": "Tokens are the small text chunks a model reads and writes, in and out."
},
"finish_reason": "stop"
}
],
"usage": {
"prompt_tokens": 12,
"completion_tokens": 18,
"total_tokens": 30
}
}
