Standard REST
Predictable shape, every time.
POST a JSON payload, get a response. Same contract whether you're calling from Python, Go, or your phone.
Chat endpoint
Synchronous request/response for simple integrations. Perfect for serverless or scripts.
{ "agent": "support" "message": "..." }
Streaming endpoint
Tokens stream as they arrive. Use Server-Sent Events for chatbots and live UIs.
data: " support"
data: " refunds"

API key auth

Production ready
Built for real workloads.
Rate limits, retries, tracing, and version control — everything you need to ship AI safely at scale.
Rate limits
Per-account quotas keep your bill predictable and your downstream services safe.
Automatic retries
Transient errors retry with exponential backoff. Your code stays simple.
Tracing built in
Every request and response is logged with latency, tokens, and cost.
Swap models
Switch from GPT-4o to Claude in the dashboard — your code never changes.
What teams say
From the people
already shipping with it.
“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.”
