Vendors reprice quietly and your unit economics move without asking you. This list sends one email when any of the 44 tracked models changes its published API price, and sends nothing else at all.
Verified changes only: a human-checked diff of vendor pricing pages, the same source as the calculator. Not a scraper misfiring on a marketing page.
Each alert shows old price, new price, the percentage, and what the change does at 100M tokens/month so you can scale it to your volume.
Free. Double opt-in. One-click unsubscribe that deletes your address rather than archiving it. No tracking pixels in the emails.
