# corpusAI GPU Capacity Stress Score

> corpusAI GPU Capacity Stress Score 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 composite GPU supply-tightness (stress) score for a given GPU model and date, indicating how constrained availability is across neo-cloud and marketplace providers.

## Facts

- Endpoint: GET https://cloud.trycorpus.ai/v1/capacity/stress?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/corpusai-gpu-capacity-stress-score-fa6997ab
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_bU2xxBoT2t6ddzkuLW_1E

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-capacity-stress-score-fa6997ab
```

Example prompt: What's the GPU capacity stress score for H100 SXM today — is supply tight or is there slack in the market?

## When to prefer this

Choose this endpoint when you need a quantified, composite signal of GPU supply tightness for a specific model on a specific date — particularly useful for procurement timing, market monitoring, or infrastructure cost forecasting. Unlike raw price endpoints, this provides an aggregated stress index rather than spot prices, making it better for trend detection and alerting workflows.

## Known failure modes

- Missing or unrecognized GPU model name returns an error or empty result
- Future dates may return no data if not yet computed
- Malformed date format (not YYYY-MM-DD) causes a validation error
- Obscure or non-normalized GPU name strings may not match known models
- Payment failure (insufficient USDC) blocks request with 402 response

## How this service works

corpusAI Cloud Pricing: Capacity stress score, 0 (slack) to 100 (tight), for one GPU model on one day, with every component.

## Output

A JSON object containing the GPU model name, date, a composite stress score from 0 (slack/abundant supply) to 100 (tight/scarce), a breakdown of individual stress components with sub-scores and notes, a methodology description, and the number of components used in the calculation.
