A flat monthly plan, starting at $5, gets you hundreds of millions of DeepSeek tokens. The API is OpenAI-compatible, so you change your base URL and nothing else.
Point any OpenAI SDK, agent or IDE plugin at api.cheapseek.ai/v1 and your existing code keeps working.
from openai import OpenAI client = OpenAI( base_url="https://api.cheapseek.ai/v1", api_key="cs-...", ) stream = client.chat.completions.create( model="deepseek-flash", messages=[{"role": "user", "content": "Refactor this function"}], stream=True, ) for chunk in stream: print(chunk.choices[0].delta.content or "", end="")
import OpenAI from "openai"; const client = new OpenAI({ baseURL: "https://api.cheapseek.ai/v1", apiKey: process.env.CHEAPSEEK_API_KEY, }); const res = await client.chat.completions.create({ model: "deepseek-v4-pro", messages: [{ role: "user", content: "Plan the migration" }], }); console.log(res.choices[0].message.content);
curl https://api.cheapseek.ai/v1/chat/completions \ -H "Authorization: Bearer $CHEAPSEEK_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "deepseek-flash", "messages": [{"role":"user","content":"hello"}] }'
Each plan comes with a monthly allowance and a rolling 7-day cap set at ¼ of that allowance, so no single week can drain the whole month. You can upgrade or cancel whenever you like.
Usage factors: deepseek-flash ×1 and deepseek-v4-pro ×3, so a Pro token uses three Flash tokens of allowance. A cached input token counts as 0.1. Once you pass a cap, requests continue at pay-as-you-go rates.
Take a typical agentic-coding month of 250M input tokens (mostly cache hits) and 25M output tokens on DeepSeek V4.1 Flash.
| Option | Approx. monthly cost |
|---|---|
| Typical closed frontier API | $400+ |
| DeepSeek pay-as-you-go, peak hours | ~$40 |
| CheapSeek Builder | $10 flat |
If a tool lets you set an OpenAI-compatible base URL, it works with CheapSeek.
Yes. We serve the official open-weight DeepSeek models at full precision, and every response includes the exact model version it came from.
Your requests don't stop. Usage over the cap is billed at pay-as-you-go rates from your prepaid balance. If you'd rather stop at the cap, turn on hard limits in the dashboard.
It keeps prices low for everyone. A few accounts can't use a whole month of capacity in a single afternoon. The window rolls, so usage drops out of it seven days after it happened.
No. We don't store prompts or completions beyond what billing and abuse prevention require.
Yes. When you upgrade, the new plan starts right away with a fresh allowance, and we prorate what you hadn't used on the old one.
Card through Stripe. Subscriptions renew monthly or yearly, and you can cancel from the billing page whenever you want.
