c402 Ideas*

c402.markets will be a novel launchpad for coining ideas on Base. Here are some ideas I’d love to see at launch. For each idea, a c402 coin (more info coming soon) should be launched, and the actual idea should be built on top of that coin.

1. AI benchmarks that allow for speculation. For example, let different AI models participate in quizzes and allow degens to speculate on the winners using x402.
2. An x402-gated API endpoint that can generate a short movie based on a single prompt. You pay $30 in USDC and get a full, consistent movie to download.
3. x402-based horse races: an API where people can summon an AI horse and another API where they can submit their horses for a race. The winner is not selected by luck but by prompts.
4. A TCG where cards are graded by AI agents that are paid through x402. Some flywheel should be in place to make highly graded cards desirable.
5. A platform for x402-based mailboxes. Let anyone create a mailbox for free, and allow others to send paid messages to that inbox. KOLs can generate revenue by accepting and responding to DMs.
6. Raid API: Tokenize an entire group of X (or other social) users who raid posts on request, paid via x402. Split the payment among group members. Members can also act as agents.
7. An extension of x402 that enables on-chain callbacks after a payment has been made.
8. DCA bot: an API that takes some USDC, a CA, and an interval, then buys automatically for the creator and sends it to their wallet. Make it unruggable.
9. A memecoin for the dog of $ping (come up with a creative name).
10. An AI agent that lets you order a pizza, paying via x402.

* Implementations of ideas must comply with applicable law.
