An AI API for developers who don't want to rebuild the plumbing.
Build with Charigents, visual steps, event alerts, and voice tools in one workspace. Business adds a REST API, which lets your software talk to Charigent, and BYOK, which lets you connect supported AI service keys for a 5% platform fee. The catalog includes more than 300 connections.
The developer problem
Building AI features shouldn't take months
Integration plumbing delays the product
Model calls, retrieval, orchestration, persistence, and monitoring can turn one product idea into several systems your team must maintain.
Managing multiple API keys is a security risk
Keys scattered across local files, environments, and services make access reviews, rotation, and provider-level cost tracking harder.
No visual workflow tooling
When every branch, condition, and retry is hard-coded, even a small workflow change can require engineering time and a new deployment.
Platform capabilities
The AI building blocks you actually need
Charigent Builder
Build Charigents with your own knowledge base. Programmatic REST API access is available on Business.
Flow Builder
Visual drag-and-drop automation canvas. 33 node types, conditional branching, and webhook triggers.
Chat Widgets & Embeds
Embed a Charigent with a script tag and configure supported visual and behavior settings. Website widgets require Pro.
BYOK Support
Connect supported provider keys on Business. Provider quotas and policies still apply, and Charigent charges a 5% platform fee for BYOK usage.
Webhooks
Subscribe to Charigent events, flow completions, and generation results. Build event-driven AI workflows.
Voice AI
Add real-time voice sessions to eligible Charigents. Voice access begins on Pro, with premium voice and cloning capabilities on Business.
Simple REST API
Call your Charigent from an application
// Query your Charigent via API
// Note: /api/rag-agent/ is the current path for this endpoint.
const response = await fetch('/api/rag-agent/chat/your-agent-id', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': 'your-api-key',
},
body: JSON.stringify({
message: 'How do I reset my password?',
}),
});
const reply = await response.text();Call this AI API for developers from your own app.
Wire up the endpoint above, then build the rest of your workflow around it.
