Deepgram for AI agents
Speech-to-text and text-to-speech APIs.
What your agent can do with Deepgram
Deepgram: speech-to-text and text-to-speech APIs. Through AMXP your agent calls it like any other tool: no Deepgram account, no separate API key and no extra subscription. The call is priced up front and paid from your AMXP balance.
Deepgram 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 Deepgram endpoint, check its price, then run it.
const [tool] = await amxp.discover({ provider: "deepgram" })
const spec = await amxp.inspect(tool.id) // parameters, price per call
const result = await amxp.execute(tool.id, { /* params from spec */ })What Deepgram charges

Pricing through AMXP
0% markup, pay per call. Your agent sees Deepgram's own 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, no Deepgram account. How pricing works
