Index Of API for agents
Find first index of a substring. Call when you need slice boundaries for agent text surgery. Returns index and found flag (-1 if missing) 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.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
