Sign in with your OPTES account and create a key in one click. The key is shown once, so keep it somewhere safe.

Requests need credit: top up from $5 on the same page.

Put your key in OPTES_API_KEY and run it. That is all.

curl https://api.optes3.com/v1/chat/completions \
  -H "Authorization: Bearer $OPTES_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "optes-1.2-super-lite",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

import os, requests

r = requests.post(
    "https://api.optes3.com/v1/chat/completions",
    headers={"Authorization": f"Bearer {os.environ['OPTES_API_KEY']}"},
    json={
        "model": "optes-1.2-super-lite",
        "messages": [{"role": "user", "content": "Hello!"}],
    },
)
print(r.json()["choices"][0]["message"]["content"])

// Node 18+ or the browser
const r = await fetch("https://api.optes3.com/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.OPTES_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    model: "optes-1.2-super-lite",
    messages: [{ role: "user", content: "Hello!" }],
  }),
});
const data = await r.json();
console.log(data.choices[0].message.content);
