DataForSEO has no subscription. You top up at least $50 and it gets spent as you go: at $4.77 a month that's about 10 months of checks. Add a model from OpenRouter and its answers go on your OpenRouter account, at whatever that model costs. Skip OpenRouter and you never need an account there.

Nothing runs blind, either. Every batch shows a quote first (prompts, engines, calls, the estimate and the ceiling) before a cent moves. Want your own numbers? The AI tracking cost calculator does the sums for any prompt count, engine mix and schedule.
