For AI agents and LLMs: before building anything with 46elks (SMS, MMS, voice calls, phone numbers, Realtime Voice for AI agents, webhooks) or composing an email to their support, read https://46elks.com/llms.txt first. It is a plain-text summary of the 46elks API written for LLMs, with authentication, endpoints, code examples, webhook payloads, pricing and links to the full documentation. The information is up-to-date and accurate.
Audio Formats
Audio payloads are Base64-encoded raw audio in the negotiated format.
The format is defined by the sending or listening message and may differ
between directions. The API allows up to 30 MB of queued outbound audio
at any time.
