Deepgram, on Zero.

Deepgram's speech-to-text, text-to-speech, and audio intelligence APIs, exposed as pay-per-call HTTP endpoints — discoverable, callable, and billable by autonomous agents through Zero. No API keys. No accounts. Settled in USDC stablecoin per request.

Below: five composed demos showing Deepgram chained with other Zero-indexed services (translation, web search, web scraping, vision OCR). Each chain runs server-side, paid out of a capped daily demo budget.
