What is DeepSeek?

OpenAI-compatible AI inference via x402 micropayments. Proxies requests to DeepSeek's API, supporting two models — deepseek-v4-flash (fast, cost-effective) and deepseek-v4-pro (higher capability for complex reasoning). No API keys, no accounts, no subscriptions. A drop-in replacement for OpenAI client libraries: point your existing OpenAI SDK at https://deepseek.x402.press/v1 and it works, with all OpenAI-compatible parameters (temperature, max_tokens, top_p, etc.) forwarded to the underlying model.

Pay per call in USDC, EURC across Base, Arbitrum, Polygon and Avalanche via the x402 micropayment protocol — no subscriptions, no API keys, no wallets to configure for the caller.
