corpusAI Cloud Pricing API

Every spot price change collected directly from the provider APIs (EC2 DescribeSpotPriceHistory, GCP Capacity Advisor, Azure Resource Graph), stored as immutable events with the exact timestamp, availability zone and product, plus the full legacy history behind the dashboard: AWS daily back to 2022-05 (measured, with open/high/low/close), daily averages back to 2024 (SpotLake TITANS, all providers), and AWS monthly back to 2014 (USC/ISI archive). Every row names its source. Endpoints return raw events, hourly bars, stitched daily and monthly series across all eras, the current price per zone, whole-provider snapshots and region-level file exports, on-demand and reserved-instance list-price history, Azure eviction-rate history, and GPU rental quotes from neo-clouds and marketplaces (RunPod, Vast.ai, DataCrunch, Lambda, Vultr, Linode, Oracle) normalised to USD per GPU-hour with hyperscaler spot beside them. The free public dashboard at https://tools.traversa.dev/cloud-pricing shows one daily average per instance for the trailing 90 days (weekly for a year, monthly beyond); this API is the full-precision, per-zone tier behind it. Built and operated by corpusAI (https://www.trycorpus.ai), software that outlives its owners.
