SDK overview - Histeeria

The Histeeria SDK sends agent decisions to the API with zero latency impact on your agent.

Packages

Language	Install	Import
Python 3.8+	`pip install histeeria`	`from histeeria import Histeeria`
Node 18+ / TS	`npm install histeeria`	`import { Histeeria } from "histeeria"`

Every SDK exposes:

Method	Purpose
`observe(...)`	Send one decision (async, non-blocking)
`trace(...)`	Multi-step agent context manager
`flush()`	Drain queue before process exit (especially serverless)

Zero latency

Sends run in a background queue. observe() returns immediately.

Zero dependencies

Python uses stdlib only. TypeScript uses platform fetch.

Failure silent

Network errors never throw to your agent loop. Enable debug=True locally to see logs.

from histeeria import Histeeria

h = Histeeria()  # reads HISTEERIA_API_KEY
h.observe(input=messages, output=response, agent_id="bot-1")
h.flush()
