What is Hyperfusion?

OpenAI-compatible AI inference via x402 micropayments, serving three open-weight models from Hyperfusion's UAE data centres: deepseek-ai/DeepSeek-V4-Flash-0731 (1M context), Qwen/Qwen3.8-27B (262K context) and MiniMaxAI/MiniMax-M2.7 (197K context). The model must be named on every request — there is no default, because a silent default would bill you for a model you did not choose. No API keys, no accounts, no subscriptions: point an existing OpenAI SDK at https://hyperfusion.x402.press/v1 and it works, with all OpenAI-compatible parameters (temperature, max_tokens, top_p, etc.) forwarded upstream. A call costs a flat price in one of two bands, set by the model and the size of the prompt; there is no peak-hour surcharge. The 402 payment challenge always carries the exact amount for the request, so clients never compute it. A metered (`upto`) accept is also offered: authorize the worst case — the prompt plus the completion you allow — and settle the actual input and output tokens, never above that ceiling. Nothing in the metered path caps context or output.

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

Method	Endpoint	Description	Tier
`POST`	`/v1/chat/completions`	OpenAI-compatible chat completions over DeepSeek V4 Flash, Qwen3.8-27B or MiniMax M2.7. The model is required. Price is a flat amount in one of two bands (prompt under or over ~4,000 estimated tokens), set by the model; there is no peak-hour surcharge. Additional OpenAI parameters (temperature, max_tokens, top_p, frequency_penalty, presence_penalty, stop, etc.) are forwarded. The optional metered (`upto`) accept authorizes the prompt plus your `max_tokens` as a ceiling and settles the measured input and output tokens. Streaming is not supported on the paid route.	deepseek

Data sources

Hyperfusion API — Proxied server-side; the service's own API key is never exposed to callers. Inference runs on Hyperfusion's GPUs with UAE data residency.
