PostWire does what people pick Zernio (Late) for, letting an agent or a script publish to many networks through one API, and prices it differently: per brand, not per connected account ($9 for 3 brands with every network; Zernio: $6 per account after the first 2), with the REST API, the MCP server and the n8n node on the Free plan, and approval rules so an agent never posts something a person has not seen.

Zernio is the posting API many developers still know as Late or getlate.dev. It now bills per connected account and sells ads, messaging and calls on the same meter.
PostWire stays focused on publishing: one idea written as a native post per network and published by you or your agent. What small teams and agencies get from it:
