# AxonOS GPU-Native Desktop for Scientific Computing

> AxonOS GPU-Native Desktop for Scientific Computing is a paid API for AI agents from app.axonos.io, paid per call via x402, $1/call, status unknown (last checked 2026-10-09).

Provisions an on-demand GPU-accelerated Linux compute session with SSH access, billed per minute and paid in USDC on Base via the x402 protocol.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability axonos-gpu-native-desktop-for-scientific-computing-8e373cdc -d '<json body>'
```

Example prompt: Spin up a GPU Linux session on AxonOS for me — I need SSH access to a small GPU instance right now and I'll pay in USDC on Base.

## When to prefer this

Choose this endpoint when you need an immediately available, pay-per-minute GPU Linux environment accessible via SSH without any subscription or account setup, and when your payment flow uses USDC on the Base network via the x402 protocol. Ideal for AI agents orchestrating short-lived compute jobs, scientific simulations, or ML training runs that need real GPU hardware on demand.

## Known failure modes

- Insufficient USDC balance or failed x402 payment — session not created, payment.verified = false
- No available GPUs of the requested profile — session not granted
- Invalid or missing request body fields — HTTP 400 bad request
- Network timeout during session provisioning
- Session expires mid-use if credits run out and no renewal is triggered

## How this service works

On-demand GPU Linux compute sessions with SSH access, rented by the minute and paid in USDC on Base via x402.

## Output

Returns a session object indicating whether access was granted, SSH connection details (host, port, username), a unique session ID, the list of assigned GPU IDs, remaining session time in seconds, credited minutes, and the on-chain settlement transaction hash confirming the USDC payment.
