communications
APIs.

Voice, Messaging, Verify, Lookup and Numbers behind one developer API. One key, every channel, pay only for what you send. Ship in minutes — not a procurement cycle.

// products

One platform. Every channel you ship on.

Composable building blocks for communications. Call them à la carte or wire them together — same key, same base URL, same predictable JSON.

live

Verify

Phone & email OTP across SMS, voice, WhatsApp and email — you never store a code or run a timer. We generate, deliver, rate-limit and lock.

POST /verify/start
POST /verify/check  → approved
Verify reference
live

Lookup

Validate & normalize any number to E.164, with country, carrier-style line type and national format. Clean your list before you spend a cent on delivery.

GET /lookup?number=+6591234567

Voice

Programmable calls, OTP-over-voice and call control on B'Yond's own switch (ByondSBC + ByondSwitch). Wired now — the data plane returns channel_unavailable until launch.

POST /verify/start
  { "channel": "voice" }

whatsapp live

Messaging

SMS & WhatsApp programmatic messaging. WhatsApp delivery is live today; A2P SMS sending lands with byondsms.com — one API, many senders.

POST /verify/start

Numbers

Provision local, national & toll-free numbers in 100+ countries as sender IDs and inbound endpoints — programmatically, via the same key.

Numbers on ByondVoice

Your keys, hashed.

Mint scoped API keys in the console. The secret is shown once, then stored only as a hash — rotate or revoke any time.

Open the console
// why ByondAPI

Built for developers who ship.

01

One platform

Verify, Lookup, Voice, Messaging and Numbers under a single base URL and a single key. Stop stitching four vendors together.

02

Hashed keys

Keys are prefix.secret; the secret is shown once and stored only as a hash. Scope them, rotate them, revoke them.

03

Multi-channel

Flip channel from sms to voice, whatsapp or email — same request shape, graceful fallback when a channel isn't ready yet.

04

Pay-as-you-go

No seats, no minimums, no annual lock-in. Pay per verification and per lookup, metered to the request. Scale down as easily as up.
