Simple pricing for AI vendor monitoring
Start free or choose a paid tier — one job: catch the price move before it shows up on your invoice. These tools tell you what you spent. VendorSpies tells you when the rules changed — so the next OpenAI, Anthropic, or Google price recalibration lands in your inbox, not on your AI bill.
No proxy, SDK, or production-traffic access required. VendorSpies monitors the source—not your prompts. Available now across 30 first-party provider baselines plus 400+ OpenRouter-listed models.
