Code samples

curl https://onlist.io/v1/chat/completions \
  -H "Authorization: Bearer $ONLIST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "model": "amazon/nova-pro-v1",
       "messages": [
         {
           "role": "user",
           "content": "Explain quantum entanglement in one paragraph."
         }
       ]
     }'

Replace $ONLIST_API_KEY with the API key from your Keys page.

Authentication

All requests must include an Authorization: Bearer <TOKEN> header. Generate keys from the Keys page; keys can be scoped to specific models, groups, IP ranges, and rate limits.

Enable streaming

Add "stream": true to receive partial responses as server-sent events in real time.

Streaming example

curl https://onlist.io/v1/chat/completions \
  -H "Authorization: Bearer $ONLIST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

         {
           "role": "user",

       ],
       "stream": true
     }'

Supported parameters

Name	Type	Description
`max_tokens`	integer	Maximum number of tokens to generate in the completion.
`stop`	string \| array	Up to 4 sequences where the API will stop generating tokens.
`temperature`	number	Sampling temperature between 0 and 2. Higher values make output more random.
`tools`	array	A list of tools the model may call. Currently supports functions.
`top_k`	integer	Limits token selection to the k most likely candidates at each step.
`top_p`	number	Nucleus sampling. The model considers tokens with top_p probability mass.

These are the request parameters this model accepts. Parameter semantics follow the OpenAI Chat Completions specification.
