Toolkit Pack — the prepaid form of the inspector toolkit: one $1.00 payment buys 125 checks spendable on Sign Reader, Score Book, or Guard in any mix ($0.008/check instead of the $0.01 singles), good for 90 days. Spend credits via POST /v1/sign-read, /v1/score-book, or /v1/guard (body pack_id or X-Toolkit-Pack header); read the balance free at POST /v1/toolkit/pack-balance. An exhausted pack returns 402 rather than charging per call. Use this when your agent runs the toolkit regularly.
