• compute_instances — on-demand Linux/list prices; six providers, general/compute/memory/burstable families. monthly_usd = hourly_usd × 730.
• object_storage — standard-tier price in USD per GB-month.
• egress — free monthly allowance then USD per GB for internet egress.

Terms & fair use

• Free, no key. No authentication and no sign-up. CORS is open (Access-Control-Allow-Origin: *) so you can call it from the browser.
• Attribution required. If you show these numbers, credit SpendArk and link back.
• Cache it. The file is CDN-cached for one hour (Cache-Control: public, max-age=3600). Prices are re-checked monthly, so caching for hours is fine — please don't hammer it. There is no per-key rate limit today; heavy or commercial use should cache locally or get in touch.
• Not a contract. Representative list prices for planning, not a billing source of truth — always confirm on each provider's own pricing page. See our methodology.
