# Hyperfusion — x402.press

> DeepSeek, Qwen and MiniMax open-weight inference on GPUs domiciled in the UAE — inference and data stay in-country, without an API key or credit card.

State: sellable
State note: Sellable as of 2026-10-30: GET /health answers 200 and every listed model/operation returns a 402 quote in the live handshake (measured 2026-10-30T23:10Z, see quote_basis).

## Price — exact (what a fixed call costs)

| chain | asset | exact USD |
|---|---|---|
| Base | USDC/EURC | 0.007 |
| Arbitrum | USDC | 0.006 |
| Polygon | USDC | 0.005 |
| Avalanche | USDC | 0.002 |
| Ethereum | USDC | 3.00 |
| Robinhood | USDG | 0.007 |
| Arc | USDC | 0.007 |

Metered ceiling on Base at max_tokens: 1000: 0.02595 USD (the highest of this service's models; per-model ceilings are in the JSON).
The same request with max_tokens unset tops out at 0.527789 USD — that authorises the model's whole output allowance, so it is a worst case, not a price. Every chain's ceilings are in https://x402.press/services/hyperfusion.json under quotes[].ceilings[].

Measured: 2026-10-30T23:28:43Z (unpaid request -> 402 Payment-Required header (first round of the handshake only; nothing signed, nothing settled)).

## Operations

- POST https://hyperfusion.x402.press/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.

## Free endpoints

- GET /v1/models — List the three served models
- GET /hyperfusion/feedback — Return the 50 most recent feedback entries
- POST /hyperfusion/feedback — Submit feedback (response_id, rating 1-5, optional comment)

## Start

Send the request unpaid, read the 402, sign the amount it quotes, send it again. Nothing is charged for the first round.
