litellm-openttt

TTTPS Proof-of-Time success callback for LiteLLM. Attaches a cryptographic audit-trail timestamp (a signed Proof-of-Time receipt) to every litellm.completion() / litellm.acompletion() response, sealed against the public self-serve KPP Provenance API.

This attaches a cryptographic audit-trail timestamp and integrity hash. It does not certify legal or regulatory compliance (EU AI Act, FDA, and so on). Treat it as an audit-trail timestamp, not a compliance claim.

Install

pip install litellm-openttt

Usage

import litellm
from litellm_openttt import TTTPSTimestampLoggerKPPLive

litellm.callbacks = [TTTPSTimestampLoggerKPPLive()]

resp = litellm.completion(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "hi"}],
)

print(resp.tttps_receipt)
# {"status": "ok", "receipt_id": "...", "receipt": "...", "time": "...", ...}

Set KPP_API_KEY (mint one for free via POST https://kpp.kenosian.com/v1/keys) and optionally KPP_BASE / KPP_TIMEOUT_S as environment variables.

Fail-open: any network/upstream error degrades the receipt to {"status": "degraded", ...} and is logged. It never raises out of the callback, so the LLM response itself is never blocked or mutated.
