Look up tracked hourly GPU rental prices (H100, A100, RTX 4090 and more) with vendor source links, check dates and day-over-day price changes, and search work-stack tool deals (compute, search, crawl, hosting, email) through the Lantern Works hosted MCP server or its public JSON API. No API key needed. Some result links are referral links and are flagged in the data.

Public JSON API (GET, no auth)

• GPU prices: https://thelanternworks.com/api/v1/gpu-prices.json (keys include rates, vendors, feed_updated_at, prices_verified_through, methodology; each rate row has gpu, vram_gb, price_usd, hourly_equiv_usd, tier, billing, interruptible, affiliate, verified_at and a source link)
• GPU price changes: https://thelanternworks.com/api/v1/gpu-price-changes.json (RSS: .xml)
• Work-stack deals: https://thelanternworks.com/api/v1/deals.json

bash

curl -s https://thelanternworks.com/api/v1/gpu-prices.json | jq '.rates[] | select(.gpu=="H100") | {advertiser, hourly_equiv_usd, tier, verified_at, affiliate}'

Reading the data correctly

• "Cheapest" means cheapest among tracked providers only, not the whole market.
• Prices are re-read daily from each vendor's own pricing page; always report the verified_at / check date and link the source so the user can confirm.
• price_usd: null means the price is unknown, not free.
• Rows with affiliate: true use referral links; Lantern Works may earn a referral reward. Tell the user when a link you share is a referral link, and offer the vendor's direct pricing page.
• Present options neutrally and let the user's needs (price, availability, interruptibility, billing unit) decide.

When not to use

Consumer/entertainment purchases (streaming, gaming, food delivery, etc.).
