P402.io - Route, verify, and settle paid API calls with clear traces

Most AI apps waste 70% of their budget. Wrong models. No caching. Payment fees that destroy micropayments. P402.shop: Compare 50+ AI APIs (GPT-5.2, Claude Opus 4.5, Gemini 3, more). Find the right model for your use case. See costs explode from 100 to 1M users. Free. P402.io: Accept micropayments without Stripe's $0.30 killing you. 1% flat fee. Built on x402—HTTP's payment standard, finally working. Vibe-coded apps break at scale. Optimized ones don't.
