Micropayments were impractical with card rails: fees dwarfed the amount. x402 + stablecoins change that, making per-request pricing of a few cents — or fractions of a cent — viable at last. These projects implement micropayment metering, per-request billing and settlement for APIs and agents.
Here are the micropayment projects in the directory.
The Micropayments category right now
The directory currently tracks 133 Micropayments projects. ClawRouter leads the group with 6,661 stars, and 5 of them have cleared 100 stars, 1 of those past 1,000. Half the group sits at 1 stars or below, which is the honest shape of this space today: a short head of real adoption and a long tail of experiments.
TypeScript (50%) and JavaScript (14%) dominate the implementation languages here, and xenarch-ai is the most prolific publisher with 5 Micropayments repositories. The recurring GitHub topics are micropayments, ai-agents, x402.
57 of the 133 projects were updated in the last 30 days and 80 in the last 90 (60%), so this is an actively moving category. 3 have had no commit for over a year. The newest entrant is vscode-x402, first published 2026-06.
