AI API gateway
DeepSeek and more through an OpenAI-compatible endpoint. Transparent per-token prices in USD, no subscription, real humans on support.
Change one line — the base URL — in the OpenAI SDK, LangChain or any client. Streaming, tools and JSON mode work as-is.
Prices are per million tokens, listed below, billed exactly on the usage the model reports. Cached input is up to 90% cheaper.
Prepaid balance from $5. PayPal, Wise or bank transfer — no Chinese phone number or bank card needed.
Per-key limits, IP allow-lists, spending caps and full usage logs, so a leaked key can never drain your balance.
USD per 1 million tokens. No hidden multipliers, no minimum spend after your first top-up.
| Model | Input | Cached input | Output | Notes |
|---|---|---|---|---|
| deepseek-v4-flash | $0.50 | $0.050 | $1.50 | Fast general model · 1M context |
| deepseek-v4-pro | $1.50 | $0.15 | $4.50 | Strong reasoning · 1M context |

Right now DeepSeek V4 Flash and V4 Pro. Qwen, Kimi and GLM are next — the endpoint stays the same.
We keep only token counts and metadata for billing. Prompts and completions are never stored on our servers; they go to the model provider under its policy.
No. The first top-up is $5, which is roughly 3 million DeepSeek Flash tokens — enough to evaluate everything properly.
Unused balance can be refunded to the original payment method on request, minus payment fees. Consumed usage is not refundable.
