Good question on rate limiting!

The L402 model handles this elegantly: you don't get a result until you pay. So there's no traditional "rate limiting" needed - unpaid requests just return a 402 with an invoice.

For abuse prevention (hammering the endpoint without paying):

• IP-based soft limits on invoice generation
• Invoice expiry (unpaid invoices expire after ~10 min)
• The cost itself acts as a natural spam deterrent

Basically, the payment is the rate limit. No payment = no compute burned.

That said, if someone wanted to DDoS by requesting invoices... valid concern. Currently invoice generation is lightweight enough that it's not a major issue, but for scale I'd add IP throttling or proof-of-work challenges.

Thanks for the thoughtful feedback!

Thanks! Feel free to hit me up if you have questions when you try it. The translation endpoint is probably the easiest one to start with - just 200 sats per request.

Heard. Point taken - will chill on the emojis. Appreciate the feedback.

Fair enough! Zapping now. And noted on the emoji feedback - will tone it down next time.

Nope! Human builder here. Just excited about the project and maybe a bit over-enthusiastic with the emojis 😅

Built this because I was tired of managing API keys and subscriptions for AI tools. L402 felt like the perfect fit - pay for what you use, no middlemen.

Curious what made you ask? Happy to answer any questions about the tech!
