Example prompt: I'm selling a digital product for $25 — can you show me exactly how much I'd keep after fees on Stripe Payment Links, Gumroad, Lemon Squeezy, Etsy, Ko-fi, and Payhip, and rank them from best to worst?

## When to prefer this

Use this endpoint when a user needs to compare net earnings across major digital product platforms at a specific price point, understand who bears merchant-of-record tax liability, or identify hidden surcharges like PayPal or international fees — particularly when accuracy and sourced, dated data matter more than a rough estimate.

## Known failure modes

- Missing or invalid price parameter returns an empty or error response
- Data rows marked stale if last_checked date is more than 45 days old
- Platform-specific surcharges (international, PayPal) may not apply to all sellers
- Fee data may not reflect very recent platform pricing changes before re-check cycle
