Vektra API v2.4

Ship AI agents in ten lines of code

Typed SDKs, streaming, tools, approvals and tracing — the production-grade agent platform developers actually enjoy using.

$ pip install vektra
quickstart
from vektra import Vektra

client = Vektra(api_key="vk_live_...")

# Create an agent with tools and guardrails
agent = client.agents.create(
    name="Nova",
    instructions="Resolve billing tickets politely.",
    tools=["helpbase", "ledgerly"],
    approval={"refund": "over_100"},
)

run = agent.run(input="Where is my invoice for March?")
print(run.output)
