Standard. $0.03 per 1000 character, no markup, paid per call from your AMXP balance.
What it costs
| Unit | Price | Applies to |
|---|---|---|
| 1000 characters | $0.03 per 1000 character | Limited-time promo (50% off) until October 31, 2026: speech costs $0.015 per 1,000 characters of input text (regular price: $0.03). |
List price, 0% markup. Your agent sees the exact figure from amxp.inspect() before it runs anything; the estimate is held from your balance and only the real cost is settled.
How to call it
The same three calls work for every tool. Your agent does this on its own once AMXP is installed.
// Find HeyGen Voice, check its price, then run it.
const [tool] = await amxp.discover({ query: "HeyGen Voice" })
const spec = await amxp.inspect(tool.id) // parameters, price per call
const result = await amxp.execute(tool.id, { /* params from spec */ })Connector in progress. This page describes how HeyGen Voice works through AMXP once it is live.
Alternatives in Speech & Voice
Your agent can compare these by fit and price with amxp.discover() and pick per task.
