Authentication

Optional

All endpoints are publicly accessible — no API key needed for current prices, providers, and GPU summaries. A free API key unlocks full price history (anonymous requests are limited to the last 30 days). Register instantly at POST /api/v1/keys — no approval, no payment. Pass the key as Authorization: Bearer <key> or ?api_key=<key>.

Quick-Start Code Snippets

Copy-paste examples using the real public endpoint and real field names. No API key required.

# Cheapest 10 H100 listings across all providers
curl "https://computecomparison.com/api/v1/prices?gpu=H100&sort=price&order=asc&per_page=10"

# All listings for a specific provider
curl "https://computecomparison.com/api/v1/prices?provider=runpod&per_page=200"

# Live-only listings (exclude fallback/cached)
curl "https://computecomparison.com/api/v1/prices?gpu=A100&source=live&sort=price&per_page=50"

`/api/v1/prices` Field Dictionary

Every field returned in each data[] item. Derived from the live API response — no fields are omitted or invented.

data[] — listing object

Field	Type	Units	Meaning
`provider`	string	—	Cloud provider display name, e.g. "RunPod", "Lambda Labs"
`gpu_model`	string	—	GPU model name as listed by the provider, e.g. "H100 80GB", "A100 SXM 80GB"
`price_per_hour`	number	USD / hr	On-demand rental price
`spot_price_per_hour`nullable	number \| null	USD / hr	Spot / interruptible price when available; null if the provider does not offer spot for this listing
`availability`nullable	string \| null	—	"high", "medium", or "low" — provider-reported stock level; null when not reported
`region`nullable	string \| null	—	Provider region identifier, e.g. "us-east-1", "US-TX-3"; null when not reported
`source`	string	—	"live" — fetched this cycle from the provider API; "cached" — from the previous cycle; "fallback" — static rate used when the provider API is unavailable
`fetched_at`nullable	string \| null	ISO 8601 UTC	ISO 8601 timestamp of when this listing was last fetched from the provider; null for fallback rows
`quality_score`nullable	number \| null	—	Internal data-quality score 0–100. 95+ = live, 70–94 = cached/estimated, below 70 = fallback
`quality_tier`nullable	string \| null	—	"live", "estimated", or "fallback" — human-readable version of quality_score
`is_outlier`	boolean	—	true when this listing's price is a statistical outlier relative to other listings for the same GPU model (more than 3 standard deviations from the mean). Useful for filtering anomalous prices.
`node_id`nullable	string \| null	—	Provider-specific node or cluster identifier when available; null for most providers
`min_rentable_gpu_count`nullable	number \| null	—	Minimum number of GPUs that must be rented together; null when not reported (treat as 1)
`gpu_count`nullable	number \| null	—	Number of GPUs in this listing when the provider bundles multiple GPUs per SKU; null when not reported (treat as 1)
`pricing_tier`nullable	string \| null	—	Provider-specific pricing tier label, e.g. "reserved", "on-demand", "spot"; null when not reported

meta — pagination envelope

Field	Type	Meaning
`total`	integer	Total number of listings matching the query (before pagination)
`page`	integer	Current page number (1-indexed)
`per_page`	integer	Number of results per page as requested
`total_pages`	integer	Total number of pages for this query
`fetched_at`	string	ISO 8601 timestamp of the most recent data refresh cycle

CORS

Responses do not currently send CORS headers, so browsers block direct cross-origin fetch calls. Browser embedding works through the widget snippets below, which load data with JSONP and need no CORS headers. For other browser use, call the API from your own backend.

Data Freshness

Prices are fetched from each provider's public API and refreshed every 15 minutes. Each listing includes a source field:live (fetched this cycle),cached (from previous cycle), orfallback (static rates used when provider API is unavailable). Responses include Cache-Control: public, max-age=60.

GPU HTML Embed Widgets

Copy and paste any widget below directly into your website's HTML. No build tools or frameworks required.

Note: These widgets fetch data client-side directly from the public API — no key required. For production use on your own site, request a standard key and replace cc_live_demo0000000000000000000000 in the snippet. The demo key is rate-limited to 500 req / 15 min and should not be used in production.

Scrolling marquee showing every provider's best price per hour, right-to-left. Drop it into any page header or sidebar.

GPU Webhooks

Subscribe to real-time GPU price change events. When GPU prices shift, ComputeComparison POSTs a signed JSON payload to your URL — no polling required.

Event Types

Event	Fires when
`price.updated`	Any GPU price changes (up or down). Default.
`price.drop`	One or more GPU prices decrease.
`price.spike`	One or more GPU prices increase.

Payload Shape

JSON — POST body sent to your URL

{
  "event": "price.drop",
  "api_version": "v1",
  "fired_at": "2025-01-15T12:15:00.000Z",
  "changes": [
    {
      "provider": "RunPod",
      "gpu_model": "H100 80GB",
      "region": "US-TX-3",
      "old_price": 2.99,
      "new_price": 2.49,
      "change_pct": -16.72,
      "availability": "high"
    }
  ]
}

Verifying Signatures

Every delivery includes an X-CC-Signature header. Verify it to confirm the request came from ComputeComparison and wasn't tampered with.

Node.js verification

const crypto = require('crypto');

function verifySignature(secret, rawBody, signatureHeader) {
  const expected = 'sha256=' +
    crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
  return crypto.timingSafeEqual(
    Buffer.from(expected),
    Buffer.from(signatureHeader)
  );
}

// Express example
app.post('/webhook', express.raw({ type: 'application/json' }), (req, res) => {
  const sig = req.headers['x-cc-signature'];
  if (!verifySignature(process.env.WEBHOOK_SECRET, req.body, sig)) {
    return res.status(401).send('Invalid signature');
  }
  const payload = JSON.parse(req.body);
  console.log(payload.event, payload.changes.length, 'changes');
  res.sendStatus(200);
});

Python verification

import hmac, hashlib

def verify_signature(secret: str, raw_body: bytes, signature_header: str) -> bool:
    expected = 'sha256=' + hmac.new(
        secret.encode(), raw_body, hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, signature_header)

# Flask example
from flask import Flask, request
app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    sig = request.headers.get('X-CC-Signature', '')
    if not verify_signature(WEBHOOK_SECRET, request.get_data(), sig):
        return 'Invalid signature', 401
    payload = request.get_json()
    print(payload['event'], len(payload['changes']), 'changes')
    return '', 200

Limits & Behaviour

›10 active webhooks per API key
›Delivery timeout: 10 seconds per attempt
›No automatic retries — use the delivery log to detect failures
›Price changes are checked every 60 seconds
›Delivery log retains the last 50 attempts per webhook
›Demo key webhooks are registered but never fired
