Everything you need to build on our AI. Add intelligent agents, multilingual voice and real-time translation to your product — get a key, make your first call, and go to production, with quickstarts, SDKs and clear limits.
Clear docs, predictable limits · no lock-in — your data and your product stay yours.

From zero to a working call in three steps.
The fastest path to building on our AI. Each step is a short guide — follow them in order and you'll be live in minutes.
Get a key
Create an account, grab your API keys, and you're ready to build — keys for testing first, then production when you are.
Make your first call
Run a single call and get a real result back — an answer, a voice reply, or a translation — with a copy-paste quickstart to follow.
Go to production
When it works, ship it. Move from test to live keys, set your limits, and watch it run — no re-architecture required.
See what each platform can do.
Adopt them on their own, or together. Each is a capability you reach over a clean interface — head to a platform to see what you can build.
NexaFlow
Add agents that automate real work — answering, routing, taking action — and call them from your product. See what NexaFlow can do.
Explore NexaFlowKASA
Give your product a voice that makes and takes calls in many languages, and remembers each customer between calls. See what KASA can do.
Explore KASAPolyglot

Practical guides and references for building, shipping and running on our AI — written as outcomes, not jargon.
Quickstarts
Copy-paste paths that get a first call working in minutes, for each platform.
SDKs
Libraries in the languages your team already uses, so you call a capability and get a result.
Integration guides
Step-by-step recipes for adding agents, voice and translation to the product you already have.
Webhooks & events
Get notified the moment something happens, so your product can react in real time.
Rate limits & reliability
See the limits up front and understand what to expect when you scale — no surprises.
Serious enough to build a business on.
Before you build.
How do I get access?
Create an account and generate your API keys from the dashboard. You can start building against test keys right away, then switch to production keys when you're ready to ship.
What languages and SDKs are supported?
We provide SDKs in the languages most teams already use, so you can call a capability and get a result without wiring it up by hand. Our voice and translation reach many languages — including ones most platforms ignore. See the quickstarts for the current list.
Is pricing predictable, and what are the limits?
Yes. You can see the limits up front, with fair pricing and no surprise behavior or bills. The rate limits & reliability guide explains what to expect as you grow.
How do I get support?
Start with the guides and references here. When you need a person, reach our team through the contact page — and partners and larger teams get hands-on enablement.
