Count Substr API for agents
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, attributed.
