USD balance, no expiry, no subscription. 3. 03 Create a key In the console, with a monthly spend limit if you want one. Use gpt-5.2 as the model id. Base URL `https://api.relayswitch.io/v1`, your key (it starts with `sk-relay-`), the model id. Nothing else changes. python 1`from openai import OpenAI` 2 3`client = OpenAI(base_url="https://api.relayswitch.io/v1", api_key="sk-relay-...")` 4`reply = client.chat.completions.create(` 5 `model="gpt-5.2",` 6 `messages=[{"role": "user", "content": "Say hello in five words."}],` 7`)` 8`print(reply.choices[0].message.content)` bash 1`curl https://api.relayswitch.io/v1/chat/completions \` 2 `-H "Authorization: Bearer $RELAYSWITCH_KEY" \` 3 `-H "Content-Type: application/json" \` 4 `-d '{"model": "gpt-5.2", "messages": [{"role": "user", "content": "Hello"}]}'` Tools, response\_format, streaming and the usage block are OpenAI's shapes; OpenAI's [GPT-5.2 model page](https://developers.openai.com/api/docs/models/gpt-5.2) documents the model's limits. Swap the id for `gpt-5.3-codex` in a coding agent or `gpt-5.6` for the newer line; the balance and the key do not change. **What is stored:** the email address, the top-ups, the keys, and one usage record per request (request id, model, token counts, charge). **Not stored:** request and response bodies, a name, an ID, a phone number, or a card for crypto top-ups.
