Pay-per-use text AI API with USDC micropayments on Solana

I built a text processing API that charges per request using USDC on Solana — no subscription, no monthly fee, just pay for what you use. API: https://textai-api.overtek.deno.net Why pay-per-use? Most text AI APIs force you into a monthly plan. If you're building a side project or running occasional batch jobs, you're paying for unused capacity. Pay-per-use makes more sense for sporadic workloads. The USDC angle came from wanting a payment model that works globally without credit cards, chargebacks, or country restrictions. Solana's fees are negligible (~$0.00025/tx).
