# corpusAI GPU & Cloud Price Fixing API

> corpusAI GPU & Cloud Price Fixing API is a paid API for AI agents from cloud.trycorpus.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns a daily median price fixing (USD per GPU-hour) for a specified GPU or cloud compute ticker, aggregated across neo-cloud providers and spot marketplaces.

## Facts

- Endpoint: GET https://cloud.trycorpus.ai/v1/index/fixing?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 corpusai-gpu-cloud-price-fixing-api-11a696d3
```

Example prompt: What's the latest corpusAI price fixing for H100 SXM on neo-clouds — give me today's median USD per GPU-hour for ticker CX.H100SXM.NEO.

## When to prefer this

Use this endpoint when you need a standardized, aggregated daily price benchmark (fixing) for a specific GPU type or cloud compute tier, rather than raw quotes. Prefer it over scraping individual cloud pricing pages when you want a single comparable median across neo-clouds or spot regions, or when you need historical price data going back years. Ideal for cost modeling, budgeting, price alerting, and competitive benchmarking of GPU infrastructure.

## Known failure modes

- Invalid or unknown ticker returns an error — must be a valid ticker from /index/tickers
- Invalid date format (not YYYY-MM-DD) returns a validation error
- Date too far in the future or before data history starts returns no data
- Payment not completed (x402 protocol) returns 402 Payment Required
- Rate limiting or quota exceeded returns 429

## How this service works

corpusAI Cloud Pricing: One day's fixing for a ticker: median USD per GPU-hour of eligible quotes, with low, high and count.

## Output

Returns a JSON object with the fixing date, ticker symbol, median USD-per-GPU-hour value, number of quotes (n), methodology description, and optionally: high/low prices, per-provider quote counts (members), per-region spot values (regions), GPU type, segment, instance type, and spread vs the NEO fixing.
