Build with qynio

One OpenAI-compatible key for frontier models — 0% platform fees, no KYC, paid in USDG on Robinhood Chain. Be calling in under two minutes.

1 · Get an API key

No account needed: open api.qyn.io/get-key and the page assigns you a unique deposit amount. Send exactly that amount of USDG on Robinhood Chain (chain ID 4663) to the address shown. The moment it confirms, your key and permanent dashboard link appear on the page — no email, no signup.

Prefer an account? Sign in with your wallet (Robinhood Wallet, MetaMask, WalletConnect) to keep all your keys and balances in one place.

2 · Make your first call

curl https://api.qyn.io/v1/chat/completions \
  -H "Authorization: Bearer qyn-live-…" \
  -H "Content-Type: application/json" \
  -d '{"model":"anthropic/claude-sonnet-5","messages":[{"role":"user","content":"Hello!"}]}'

Drop-in with the OpenAI SDK — change only the base URL and key:

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "qyn-live-…",
  baseURL: "https://api.qyn.io/v1",
});

const res = await client.chat.completions.create({
  model: "anthropic/claude-sonnet-5",
  messages: [{ role: "user", content: "Hello!" }],
});
