# corpusAI GPU Price Index

> corpusAI GPU Price Index is a paid API for AI agents from cloud.trycorpus.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).

Returns a historical daily time-series of GPU rental prices for a specified GPU model, aggregated across neo-clouds and marketplaces.

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-price-index-d7831f4f
```

Example prompt: What has the daily median rental price been for H100 SXM GPUs across all providers and markets from January 1 2024 to today?

## When to prefer this

Use this endpoint when you need day-by-day historical GPU rental price data across multiple cloud providers and spot markets for a specific GPU model. It is the right choice when tracking price trends over time, comparing hyperscaler vs. neo-cloud pricing, or building cost models for AI training budgets. Prefer this over general web search when you need structured, machine-readable time-series data rather than prose summaries.

## Known failure modes

- Invalid or unrecognized GPU model name returns an error — must use a normalized model name from /gpu/models
- Date range with no data returns an empty series array
- Missing required 'gpu' query parameter results in a 400-level error
- Payment failure over x402 results in a 402 response before any data is returned
- Future dates or dates before coverage begins may return empty or partial series

## How this service works

corpusAI Cloud Pricing: Daily USD per GPU-hour index per provider and market for one GPU model, with hyperscaler spot legs.

## Output

A JSON object containing the GPU model name, total quote count, an optional note, and a 'series' array of daily rows. Each row includes the date, provider name, market type, number of quotes, low/median/high/mean prices (USD per GPU-hour), and for hyperscaler legs: region, instance type, and GPUs-per-node count.
