Or install the SDK

For production workloads, use the real signing pipeline with KMS-custodied keys.

Python
pip install trai-light
TypeScript
npm install @trai/core
Go
go install trai.sh/sdk/go
Quick example
from trai_light import Client

client = Client(api_key="tl_demo")
cert = client.notarize(
    content="AI-generated text from my chatbot",
    system_id="chatbot-v2.1",
    regulations=["eu_ai_act_50", "pld"],
)
print(cert.id)
print(cert.verify_url)

Demo signing uses an Ed25519 dev key (not for production). For production-grade ML-DSA-65 + SCITT + RFC 3161 eIDAS timestamps, see /try.
