Models - PrimaLabs

List models

GET /models returns the models your key can call, in the OpenAI list format, plus each model’s context window:

curl -sS https://api.primalabs.ai/v1/models \
  -H "Authorization: Bearer YOUR_API_KEY"

{
  "object": "list",
  "data": [
    {
      "id": "primalabs-ai/DeepSeek-V4-Flash-0731",
      "object": "model",
      "owned_by": "openai",
      "max_input_tokens": 1048576
    }
  ]
}

Field	Meaning
`id`	The model ID you pass as `model` in a request.
`max_input_tokens`	Context window, in tokens.

Prefer this endpoint over a hard-coded list — models are added and updated over time.

Pricing

Pricing is per token with no minimums and no reserved capacity. GET /model/info returns the per-token rates for each model your key can call:

curl -sS https://api.primalabs.ai/v1/model/info \
  -H "Authorization: Bearer YOUR_API_KEY"

{
  "data": [
    {
      "model_name": "primalabs-ai/DeepSeek-V4-Flash-0731",
      "model_info": {
        "max_input_tokens": 1048576,
        "input_cost_per_token": 1.4e-7,
        "output_cost_per_token": 2.8e-7,
        "cache_read_input_token_cost": 2.8e-9
      }
    }
  ]
}

Field	Meaning
`input_cost_per_token`	Price per input (prompt) token, USD.
`output_cost_per_token`	Price per output (completion) token, USD.
`cache_read_input_token_cost`	Price per cached input token, USD. Prefix-cache hits are billed at this lower rate.
