Substack for AI agents
Newsletters and posts.
What your agent can do with Substack
Substack: newsletters and posts. Through AMXP your agent calls it like any other tool: no Substack account, no separate API key and no extra subscription. The call is priced up front and paid from your AMXP balance.
Substack is on the AMXP roadmap and not callable yet. Everything on this page describes how it will work once its connector ships.
How to call it
The same three calls work for every provider. Your agent does this on its own once AMXP is installed.
// Find the right Substack endpoint, check its price, then run it.
const [tool] = await amxp.discover({ provider: "substack" })
const spec = await amxp.inspect(tool.id) // parameters, price per call
const result = await amxp.execute(tool.id, { /* params from spec */ })Pricing
Pay per call. Your agent sees the exact price from amxp.inspect() before it runs anything, the amount is reserved from your balance, and only the real cost is settled. No monthly fee for Substack. How pricing works
Alternatives in Social Media
Your agent can compare these by fit and price with amxp.discover() and pick per task.
