API integration interface

How It Works

Three steps to AI-powered features in your app.

01

Get Your API Key

Generate a secure API key from your dashboard. Each key is scoped to your account with rate limiting and quota enforcement.

02

Call the Endpoint

Send a POST request to the chat or streaming endpoint with your agent ID and message. Standard REST — works with any language.

03

Ship to Production

Integrate the API into your app, website, or workflow. Switch models, update prompts — all without changing your integration code.

api-request.ts
POST /v1/chat/stream

{
  "agent_id": "your-agent-id",
  "message": "What's the status of order ORD-1234?"
}

One endpoint. Any agent. Instant AI in your app.

Built for Developers

A clean, simple API that gets out of your way.

REST API

Every agent exposes a standard REST endpoint. Send a message, get a response. Works with any programming language or framework.

Streaming Support

Real-time streaming responses via SSE. Show users token-by-token output for a natural, responsive experience.

API Key Authentication

Secure authentication with your personal API key (sk-so-...). Simple Bearer token auth — no complex OAuth flows.

Rate Limiting & Quotas

Per-account rate limiting and quota enforcement by plan. Predictable usage with clear limits and monitoring.

Model Switching

Change the underlying LLM at any time from the dashboard. Your API integration stays the same — zero code changes.

Integrate Anywhere

Use agents inside your apps, websites, mobile apps, Slack bots, or any workflow that can make HTTP requests.

All included from $19/month — no add-ons, no hidden fees.

Every time you want to add AI to your app, you end up writing a ton of code — managing API keys, handling conversation history, engineering prompts, counting tokens. And then six months later a better model comes out and you have to refactor everything. SentientOne just removes all of that.
