Summary
P402.io is a platform that helps AI app developers optimize costs by addressing two major issues: wrong model selection and payment fees on micropayments. The article explains that most developers waste 70% of their budget by using expensive models like GPT-5.2 or Claude Opus for tasks that could be handled by cheaper alternatives like Haiku 4.5.

P402 offers two solutions: P402.shop for comparing 50+ AI APIs to find cost-effective models, and P402.io for accepting micropayments with a 1% flat fee instead of Stripe's fixed fees.
