# GPU Forge – GPU Probe

> GPU Forge – GPU Probe is a paid API for AI agents from forge.parabellum.tech, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).

Probes and returns real-time GPU hardware status (name, VRAM, utilization, temperature) via a machine-payable HTTP call at $0.01 USDC per request.

## Facts

- Endpoint: POST https://forge.parabellum.tech/v1/jobs/gpu.probe
- Price: $0.01/call
- Payment: x402
- Status: down
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/gpu-forge-gpu-probe-86b9990f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HiB5yFuNwwJOyxEdopliZ

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 gpu-forge-gpu-probe-86b9990f -d '<json body>'
```

Example prompt: Can you probe the GPU Forge endpoint right now and tell me which GPU is available, how much VRAM is free, and what the current utilization and temperature are? I'm happy to pay the $0.01 USDC fee per probe.

## When to prefer this

Choose this endpoint when you need a lightweight, account-free, pay-per-probe way to inspect remote GPU hardware state in real time — especially useful for AI agents orchestrating compute workloads that need to check GPU availability, thermal headroom, or VRAM capacity before committing to an expensive job. Prefer this over cloud provider dashboards or SSH-based monitoring when you want a single machine-payable HTTP call with no signup or API key management.

## Known failure modes

- Payment not received or rejected: returns 402 Payment Required
- Invalid request body (missing required fields): returns 400 Bad Request
- GPU host offline or unreachable: returns 503 or timeout
- Insufficient USDC balance on Base or Polygon: payment fails, call not executed
- Rate limiting if too many rapid calls: may return 429 Too Many Requests

## How this service works

Machine-payable GPU compute. Pay per call in USDC on Base or Polygon, no accounts, no API keys.

## Output

Returns a JSON object containing the GPU's model name, total and used VRAM (in MB or GB), current utilization percentage, and temperature in Celsius — giving a real-time snapshot of the remote GPU's hardware state.
