Delx Contains Text
Check whether text contains a needle (optional ignore_case). Call when you need a cheap membership check on agent-held strings. Returns boolean result with ignore_case flag for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
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.
