Delx Count Substr
Count non-overlapping substring occurrences. Call when you preflight how often a token appears in agent-held text. Returns integer count and needle 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.
