How this service works
Cloud GPU price comparison: hourly list prices of GPU / AI accelerator instances (H100, H200, A100, L40S, L4, A10G, T4, B200, MI300X, Trainium, Inferentia ...) on AWS and Azure in US, EU and Asia regions, on-demand and Azure Spot, ranked by USD per GPU-hour. Filter by gpu model, cloud, region, pricing. Official provider price APIs, refreshed daily.
Output
A JSON object with an 'offers' array where each entry contains cloud provider, region, pricing type, instance name, GPU count, GPU model, total USD per hour, and USD per GPU-hour — the list is pre-sorted by USD per GPU-hour ascending. Also includes a 'matched' integer indicating total results found.
Example use cases
Cheapest H100 cluster for training
“Find me the cheapest on-demand H100 GPU instances across AWS and Azure right now, ranked by USD per GPU-hour — show me the top 10.”
Azure Spot GPU savings for inference
“What are the current Azure Spot prices for L40S GPU instances, sorted by cost per GPU-hour? I want to see all available regions.”
EU region GPU cost comparison
“Compare on-demand A100 GPU instance prices in European regions across AWS and Azure — I need to know which cloud and region gives me the best price per GPU-hour.”
Technical details
Endpoint
GEThttps://fx-reference-rates.regnotes.workers.dev/v1/ai/gpu-prices?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compare GPU instance prices across AWS and Azure in a single ranked call, especially when filtering by specific GPU model, region, or pricing type (on-demand vs spot). Prefer this over manual scraping or cloud-specific pricing pages when you need a normalized, cross-cloud, per-GPU-hour cost comparison updated daily.
Side effects
- No results returned if GPU model string does not match known values (e.g. misspelled model name)
- Invalid 'cloud' or 'pricing' enum values return a validation error
- 'limit' parameter must be a 1-3 digit integer; other formats rejected
- Region strings that don't match any indexed region return empty offers list
- Data may be up to 24 hours stale since prices are refreshed daily
