How this service works
corpusAI Cloud Pricing: Price currently in force per zone and product for one instance type.
Output
A JSON object containing the provider and region, the as_of timestamp (newest price event in the region), a count of records, and an array of price entries — each with availability zone, instance type, product name, USD-per-hour price, the datetime the price took effect, and age in seconds since that price change.
Example use cases
Real-time spot cost before autoscaling
“Before I spin up new spot workers on AWS, check the current spot price for a c5.xlarge in us-east-1 so I can decide if it's worth it right now.”
GCP preemptible cost for ML training job
“I'm about to kick off a training job on GCP — what's the latest preemptible price for an n2-standard-8 in us-central1?”
Azure spot pricing for budget alert
“Can you pull the current spot price for a D4s_v5 VM in Azure's eastus region? I want to know if it's gone above my $0.10/hr threshold.”
Technical details
Endpoint
GEThttps://cloud.trycorpus.ai/v1/spot/latest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current spot/preemptible instance price for a specific cloud provider, region, and instance type in real time. Prefer this over static pricing pages or manual lookups when building cost-optimization agents, autoscaling logic, or budget alerting. It covers AWS, GCP, and Azure in a single unified API and charges only $0.01 USDC per call via x402, making it cost-effective for frequent programmatic queries.
Side effects
- Missing or invalid provider enum (must be aws, gcp, or azure) returns a validation error
- Invalid or unrecognized region slug (must match /catalog slugs exactly) returns no results or 404
- Invalid instance type name (must match /instances exactly, case-sensitive) returns empty prices array
- Payment failure or insufficient USDC balance returns HTTP 402
- Rate limiting may occur for high-frequency polling
