Quickstart

Get an API key

Pick a model

List the models your key can call:

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", "max_input_tokens": 1048576 },
    { "id": "primalabs-ai/Qwen3.8-27B", "object": "model", "max_input_tokens": 262144 }
  ]
}

The id is what you pass as model. Pricing is on the Models page.

Send a request

curl -sS https://api.primalabs.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "primalabs-ai/DeepSeek-V4-Flash-0731",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

from openai import OpenAI

client = OpenAI(
    base_url="https://api.primalabs.ai/v1",
    api_key="YOUR_API_KEY",
)

r = client.chat.completions.create(
    model="primalabs-ai/DeepSeek-V4-Flash-0731",
    messages=[{"role": "user", "content": "Hello"}],
)
print(r.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.primalabs.ai/v1",
  apiKey: "YOUR_API_KEY",
});

const r = await client.chat.completions.create({
  model: "primalabs-ai/DeepSeek-V4-Flash-0731",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(r.choices[0].message.content);

Stream the response

Set stream: true to receive tokens as server-sent events:

curl -sS -N https://api.primalabs.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "primalabs-ai/DeepSeek-V4-Flash-0731",
    "messages": [{"role": "user", "content": "Hello"}],
    "stream": true
  }'

stream = client.chat.completions.create(
    model="primalabs-ai/DeepSeek-V4-Flash-0731",
    messages=[{"role": "user", "content": "Hello"}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

const stream = await client.chat.completions.create({
  model: "primalabs-ai/DeepSeek-V4-Flash-0731",
  messages: [{ role: "user", content: "Hello" }],
  stream: true,
});
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0].delta.content ?? "");
}

Already using the Anthropic SDK or the OpenAI Responses API? The same key works against POST /messages and POST /responses — see the endpoint list.
