Fynx

Nov 2025

Fynx is an open-source platform that lets developers turn any API endpoint into a pay-per-call API using Solana micropayments.

It transforms your ordinary API routes into paywalled endpoints powered by Solana.
Users pay per request (like $0.01 or $0.05) — and developers earn directly to their wallets.
