Join Lines API for agents
Join an array of lines with a separator. Call when you reassemble agent-held line lists for prompts or files. Returns joined text and line count 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.
