# Tarnak GPU Prices API

> Tarnak GPU Prices API is a paid API for AI agents from api.capousd-student-tools.me, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Returns current GPU rental pricing offers, optionally filtered by GPU model (e.g. A100), including uptime and hourly USD cost.

## Facts

- Endpoint: GET https://api.capousd-student-tools.me/v1/gpu/prices?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/tarnak-gpu-prices-api-daad5eaa
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_O1tC4SOR-xWdmPNpLiZ36

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 tarnak-gpu-prices-api-daad5eaa
```

Example prompt: What's the current hourly rental price for an A100 GPU right now, including uptime stats?

## When to prefer this

Use this endpoint when an AI agent needs current, pay-per-call GPU rental pricing without API key registration, especially when operating on the Base network using x402/USDC micropayments. Ideal for cost-estimation workflows, budget planning for ML workloads, or comparing compute market rates with real uptime data. Not suited for historical price analytics or multi-cloud comparisons beyond what the service indexes.

## Known failure modes

- Invalid or unsupported GPU model filter returns empty offers array
- Payment not received or x402 handshake fails returns 402 Payment Required
- Rate limit exceeded (beyond 10 free verdicts/IP/day) without payment returns 402
- Malformed query parameters return 400 Bad Request
- Service temporarily unavailable returns 503

## How this service works

Keyless pay-per-call APIs for AI agents on Base: token risk verdict, rug/honeypot report, gas estimate, URL-to-markdown and more. x402 v2, USDC, no API key or signup. 10 free verdicts per IP per day.

## Output

A JSON object containing a list of GPU rental offers, each with GPU model name, hourly price in USD, the network (e.g. Base), 30-day uptime percentage, and a timestamp for the offer.
