# Good-neighbor passport: agent traffic governor (P20) — TextForAgents LLC
A budget-bearing RFC 9421-style Ed25519 traffic passport: operators sign per-host budgets capped at directory-published ceilings; hosts verify and meter with graduated allow / throttle / charge / block; a hash-chained compliance log restores an honest fleet in a dispute.
**Solo $5/mo** (1 operator, up to 5 agents, per-host budgets + compliance log) · **Fleet $15/mo** (up to 50 agents, etiquette engine, host-dispute evidence pack) · **Host-side $19/mo per host property** (verification/metering API, graduated allow/throttle/charge/block).
One-time trial: first month of Solo free, once per operator account and once per payer wallet, server-enforced.
Start: POST /register, then POST /trial (one-time) or POST /subscribe (x402). Library: GET /package (good_neighbor_passport 1.0.0). Support: support@textforagents.com
