AI Compute GPU Spot Price Feed
x402
AI Compute GPU Spot Price Feed is a paid API for AI agents from ai-compute-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).
Returns smoothed spot, 1-week, and 1-month GPU rental marks (bid/ask/mid) in USD per GPU-hour, aggregated from multiple public pricing sources.

How this service works
Hourly GPU rental term structure: smoothed spot, 1w, and 1m marks in USD per GPU-hour, collected from public pricing sources. Not a forecast, a traded forward curve, or a recommendation. Trailing tenors are labeled trailing_median. Descriptive GPU rental marks aggregated from public sources. Not a forecast, a traded forward, or a recommendation.
Output
Returns a JSON object with a timestamp (asOf), pricing tier, unit (USD/GPU-hour), and an array of marks per GPU type. Each mark includes bid, ask, mid, mark price, tenor (spot/1w/1m or trailing_median), GPU type, and volume. Also includes a confidence block listing the number of sources, source names, and the age of the newest and oldest observations, plus a disclaimer.
Example use cases
Budget estimation for AI training run
“I'm planning a training job that needs H100 GPUs — what's the current on-demand market rate per GPU-hour so I can estimate my total compute cost?”
Spot vs on-demand price comparison
“Can you pull the current spot pricing versus on-demand pricing for H100 GPUs and tell me how wide the spread is between bid and ask?”
GPU cost monitoring for FinOps dashboard
“Fetch the latest aggregated GPU rental marks for all tracked GPU types on on-demand pricing so I can update our infrastructure cost dashboard.”
Technical details
Endpoint
GEThttps://ai-compute-production.up.railway.app/v1/compute/spot?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, multi-source aggregated view of GPU rental market rates in USD per GPU-hour, including bid/ask spreads and term structure (spot, 1-week, 1-month). Prefer this over scraping individual cloud providers when you want a normalized, smoothed market mark across sources with confidence metadata. Not suitable for actual procurement, trading, or forecasting — this is descriptive pricing data only.
Side effects
- Invalid GPU type string returns empty marks array or 400 error
- Unrecognized pricing enum value may cause validation error
- Stale data if public sources are temporarily unavailable — confidence.ageSecondsOldest will be elevated
- No marks returned if the requested GPU type has no tracked pricing data
- Rate limit or payment failure returns 402 if x402 payment is not processed
