Can I Use the DeepSeek API for Free? Honest Answer

By the Zylo team · Updated June 8, 2026 · 4 min read

Can you use the DeepSeek API for free? The honest answer is that getting a key is free and you can prototype for free, but DeepSeek itself is not a free model. On Zylo AI you can create a free API key and a free account with no credit card, and you can build and test on Basic-tier models within the free Basic plan allowance. DeepSeek, however, is billed per token from credits on a paid plan. The genuinely good news is that DeepSeek is among the cheapest capable models available anywhere, so at scale it is close to free in practice — but “close to free” is not “free,” and this guide keeps that line clear.

What you can do without paying

The free Basic plan requires no credit card and gives a daily allowance of roughly 200,000 tokens and 7,200 requests, a rate limit of 10 requests per minute, and up to 200,000 input characters per request. That allowance runs on Basic-tier models — lightweight options such as a Google Flash-Lite class model or a gpt-5-nano-class model — which are text only and not multimodal. You can use this free tier to build your application end to end, wire up your prompts, and validate behavior before spending anything. The free plan carries no credits, because credits come only with paid plans. So the free part is real and useful: the key, the account, and a working daily allowance on Basic-tier models. In practice that free envelope is enough to do real engineering: you can stand up the whole request-and-response loop, shape your prompts, handle errors, and confirm the behavior you want, all before a single token is billed. The point of starting here is to get every part of your integration right while it costs nothing, so that when you switch the model id over to DeepSeek you are paying only for production traffic rather than for the trial and error of building. Because the allowance refreshes daily and carries no expiry clock, there is no pressure to rush the move, and you can keep low-volume or internal workloads on the free tier indefinitely while the paid path handles anything that needs DeepSeek specifically.

DeepSeek is billed, but it is cheap

DeepSeek is not in the free tier — it is billed per token from credits on a paid plan (Go and up). What makes it attractive is the price. At point-in-time June 2026 rates, DeepSeek V4 Flash costs about $0.10 per million input tokens and $0.20 per million output tokens, which places it among the cheapest capable models anywhere. Every model is billed at its base per-token rate with no markup on usage, and the per-token cost never changes with volume, so high throughput does not raise your unit price. The only platform fee is a flat 25 percent applied once when you add credits, never on what you spend. These prices are point-in-time, so confirm them on the live pricing page before you plan a budget.

Cheap enough to feel almost free at scale

When a model costs roughly $0.10 per million input tokens, a surprising amount of real work fits into very little money. A few cents can cover thousands of short completions, which is why DeepSeek is a favorite for high-volume, cost-sensitive workloads such as bulk classification, extraction, and drafting. It will not be free, and claiming otherwise would be dishonest, but the gap between “extremely cheap” and “free” is small enough that the practical cost barrier is low. If keeping spend down is your main concern, see the cheapest AI API overview and the detailed cheapest LLM APIs in 2026 comparison to put DeepSeek alongside the alternatives.

One key, one endpoint, every model

Zylo exposes DeepSeek through the OpenAI-compatible format, so you keep the OpenAI SDK and point it at https://api.zyloai.net/v1 with a single key. Model ids are bare with no vendor prefix, so you can prototype on a free Basic-tier model and switch to DeepSeek — or to Claude, GPT, or Gemini — by changing one model-id string, without rewriting your code. That makes it easy to start free, validate your idea, and move to inexpensive per-token billing only when you are ready.
