API keys vs pay-per-use crypto payments for developer APIs?
While building HashProof I ran into an interesting dilemma. Most developer APIs use API keys and traditional billing (Stripe, subscriptions, etc). But I'm experimenting with a different approach: using x402 so agents or developers can pay per request using USDC. That makes things like: no account creation no API keys no subscriptions pure pay-per-use But I'm wondering if this might be too...

Hi Product Hunt 👋 I'm Camilo, founder of HashProof. I originally built this to solve a problem in my own event platform.

Developers can create templates, place dynamic values on designs, and define expiration dates for memberships or permanent credentials.
