Long documents and agent loops send more input per turn; the model page has a cost calculator for your own shape. Get the key ## Three steps, no DeepSeek account ### 1\. An email address Opens the account. No name, no phone number, no identity documents, no DeepSeek platform login. The email is the one thing on file. ### 2\. A top-up from $10 USDT, USDC, BTC, ETH, SOL to the address the checkout shows, or Card, Apple Pay, PayPal. The balance credits in USD; nothing is added on top and nothing recurs. ### 3\. A key Create it in the console, with a monthly spend limit if you want one. It starts with sk-relay- and calls every DeepSeek id in the table, plus every other model on the key, from the same balance. First request ## The OpenAI format, one base URL The DeepSeek ids answer the OpenAI chat completions format, the same shape [DeepSeek's own docs](https://api-docs.deepseek.com/) use. Code written for DeepSeek's platform changes the base URL and the key and nothing else. ### Python, OpenAI SDK 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="deepseek-v4-pro",` 6 `messages=[{"role": "user", "content": "Summarise this in one line: ..."}],` 7`)` 8`print(reply.choices[0].message.content)` ### curl 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": "deepseek-v4-flash", "messages": [{"role": "user", "content": "Hello"}]}'` The response headers carry the request id and, on a non-streamed answer, the charge in USD. Streaming, tool calls and JSON mode are in the [docs](https://relayswitch.io/docs). DeepSeek API key for Janitor AI ## The same key in Janitor AI and other chat clients Janitor AI, SillyTavern and similar clients take a custom OpenAI-compatible endpoint. Three values go in. text 1`API URL: https://api.relayswitch.io/v1/chat/completions` 2`API key: sk-relay-...` 3`Model: deepseek-v4-pro` Paste the chat completions URL as the proxy or API URL, the key as the API key, and any DeepSeek id from the table as the model. Every message bills per token to the balance at the rates above, and the console shows each request as it lands. The DeepSeek models answer as DeepSeek trained them. For unfiltered roleplay the [uncensored DeepSeek builds](https://relayswitch.io/uncensored) on the same key are the models made for it, and the [roleplay client](https://relayswitch.io/roleplay) runs them in the browser with no setup.
