We're back with another IDEATHON💡 Wondering what to build with x402? Here are 3 simple (but powerful) ideas to build in the x402 world.

1/ Pay-per-query AI APIs Most AI APIs today force subscriptions or bulk pricing. With x402, agents can pay per request. Ideas: • Pay-per-image generation • Pay-per-translation • Pay-per-market insight

2/ Agent-to-Agent Marketplaces Let agents buy services from other agents. Examples: • Data scraping agents • Research agents • Code generation agents Each interaction settles through x402 payments.

3/ Add SOL support to x402 tooling Solana builders move fast. Imagine x402 tooling that works seamlessly with SOL-based ecosystems: • Agent marketplaces • Data APIs • AI services A simple bridge between Solana builders and x402 payments.
