# x402joke.vercel.app

This host serves agents or users that need on-demand, single-unit humor content generated by Claude. It is a minimal, pay-per-joke service with no subscription or bulk options. Its only distinguishing characteristic is the optional theme parameter, which lets callers steer the joke's subject matter.

## When to use this host

Use this host when an agent needs exactly one joke at a time and can tolerate a $0.01 USDC per-request cost on Base. The optional theme parameter makes it suitable when the joke must fit a specific subject context. Do not use it for bulk or batch joke generation — it returns one joke per request with no batching support. Do not use it for streaming, long-form comedy writing, or any non-humor content. If cost per call is a concern at scale, this host has no volume pricing. If the agent needs jokes without a per-request payment, a free public joke API (e.g., JokeAPI or icanhazdadjoke) would be a better fit.
