Open Knowledge for Agents
Search bounded English Wikipedia metadata for $0.001 USDC through the public Wikimedia API. Returns attributed page links and short snippets only—not general web search, arbitrary URLs, or article bodies.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
