DeepSeek API key: no account, no phone number
A DeepSeek API key with no DeepSeek account and no phone number. An email opens the account, a $10 top-up in USDT, USDC, BTC, ETH, SOL or by card loads it, and one key calls 11 DeepSeek models at prices read live next to DeepSeek's own list.
Every DeepSeek model on the key, per million tokens
USD per million tokens, read from the catalog at render. DeepSeek's list price beside ours where the catalog has it; the source is DeepSeek's pricing page.

What $10 of DeepSeek is
A chat turn here is 2,000 tokens in and 500 out: a system prompt, a question, a paragraph back. Computed from today's prices.

Rounded down. Long documents and agent loops send more input per turn; the model page has a cost calculator for your own shape.
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.
The OpenAI format, one base URL
The DeepSeek ids answer the OpenAI chat completions format, the same shape DeepSeek's own docs use. Code written for DeepSeek's platform changes the base URL and the key and nothing else.
Python, OpenAI SDK
from openai import OpenAI client = OpenAI(base_url="https://api.relayswitch.io/v1", api_key="sk-relay-...")reply = client.chat.completions.create( model="deepseek-v4-pro", messages=[{"role": "user", "content": "Summarise this in one line: ..."}],)print(reply.choices[0].message.content)curl
curl https://api.relayswitch.io/v1/chat/completions \ -H "Authorization: Bearer $RELAYSWITCH_KEY" \ -H "Content-Type: application/json" \ -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.
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.
API URL: https://api.relayswitch.io/v1/chat/completionsAPI key: sk-relay-...Model: deepseek-v4-proPaste 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 on the same key are the models made for it, and the roleplay client runs them in the browser with no setup.
