Programmatic Access
to ICX Reference Rates

Introduction

The ICX API provides programmatic access to independently calculated reference rates for GPU compute. Rates are derived from a curated panel of cloud providers using a transparent trimmed-mean methodology — the same methodology published on the public site.

All API responses return JSON. Rates are denominated in USD per GPU-hour. The API is versioned and backwards-compatible within a major version.

Available Indexes

The following indexes are currently live and accessible via API:

Authentication

Authenticate using a Bearer token passed in the Authorization header. API keys are issued per subscriber and scoped to specific indexes and rate limits.

Authorization: Bearer icx_live_xxxxxxxxxxxxxxxxxxxx

API keys are available to qualified subscribers. Use the waitlist form below to request access. Do not share your API key or expose it in client-side code.

Base URL

https://icx.global/api/v1

All endpoints documented below are relative to this base URL. The current public beta uses unversioned endpoints (https://icx.global/api/) which are available for internal use. The versioned /v1 path will be available at GA.

Current Rates

Returns the latest computed ICX rates and the full provider panel that produced them.

{
  "ok": true,
  "rates": {
    "H100 SXM5 80GB": {
      "rate": 2.87,
      "panelSize": 14,
      "providerCount": 10,
      "computedAt": "2026-04-01T12:00:00Z"
    },
    "H100 PCIe 80GB": {
      "rate": 1.94,
      "panelSize": 6,
      "providerCount": 5,
      "computedAt": "2026-04-01T12:00:00Z"
    }
  },
  "fetchedAt": "2026-04-01T12:34:56Z"
}

const resp = await fetch('https://icx.global/api/v1/rates', {
  headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
});
const { rates } = await resp.json();
console.log(`ICX H100 SXM5: $` + rates['H100 SXM5 80GB'].rate);

import requests

resp = requests.get(
    'https://icx.global/api/v1/rates',
    headers={'Authorization': 'Bearer YOUR_API_KEY'}
)
rates = resp.json()['rates']
print(f"ICX H100 SXM5: ${rates['H100 SXM5 80GB']['rate']}")

curl -H "Authorization: Bearer YOUR_API_KEY" \

Rate History

Returns a time series of ICX rates for the requested GPU type. Useful for charting, volatility analysis, or anchoring forward negotiations to observed price trends.

{
  "ok": true,
  "gpu_type": "H100 SXM5 80GB",
  "history": [
    {
      "computed_at": "2026-01-01T12:00:00Z",
      "rate": 2.91,
      "min": 2.10,
      "max": 4.20,
      "providerCount": 12
    },
    // ... additional entries
  ]
}

All Indexes

Returns metadata on all tracked indexes — both live and announced-but-not-yet-live.

{
  "ok": true,
  "indexes": [
    {
      "id": "ICX-H100S",
      "gpu_type": "H100 SXM5 80GB",
      "label": "ICX H100 SXM5",
      "status": "live",
      "min_panel": 8,
      "update_frequency": "6h"
    },
    {
      "id": "ICX-H100P",
      "gpu_type": "H100 PCIe 80GB",
      "label": "ICX H100 PCIe",
      "status": "live",
      "min_panel": 3,
      "update_frequency": "6h"
    },
    {
      "id": "ICX-A100",
      "gpu_type": "A100 SXM4 80GB",
      "label": "ICX A100",
      "status": "coming_soon"
    }
  ]
}

GPU Types

Methodology

ICX rates are computed using a trimmed arithmetic mean applied to a curated panel of cloud GPU providers:

• Panel assembled from available on-demand H100 offerings, normalized to $/GPU-hour.
• Minimum panel size enforced: 8 providers for H100 SXM5, 3 for H100 PCIe. Rate withheld if panel is insufficient.
• Bottom and top 15% of prices trimmed before averaging.
• Three-layer validation applied: bounds check, delta check (vs prior reading), IQR outlier detection.
• Rates updated every 6 hours from the Get Deploying API. Each computation is stored with the full provider snapshot for audit.

The full methodology is documented on the public site.
