JEP Python SDK v0.6
Python SDK for the JEP v0.6 API seed.
This SDK targets the current JEP API shape:
POST /events/create
POST /events/verify
GET /health
It is aligned with:
draft-wang-jep-judgment-event-protocol-06draft-wang-jep-profiles-00draft-wang-jep-conformance-00hjs-spec/jep-api
Status
Experimental implementation seed.
This SDK does not define new JEP-Core semantics and does not determine legal liability, factual truth, regulatory compliance, or complete-log availability.
Installation
pip install jep-sdk-py
For local development:
pip install -e ".[dev]"
Quick Start
from jep import JEPClient, CreateEventRequest, Verb
client = JEPClient(base_url="http://127.0.0.1:8000")
created = client.create_event(CreateEventRequest(
verb=Verb.JUDGMENT.value,
who="did:example:agent-789",
what={"claim": "approve"},
))
print(created.event_hash)
verified = client.verify_event({
"event": created.event.to_dict(),
"mode": "archival",
})
print(verified.valid)
Core Types
JEPEventCreateEventRequestEventResponseVerifyEventRequestValidationResultHealthResponse
Supported verbs:
Verb.JUDGMENT
Verb.DELEGATION
Verb.TERMINATION
Verb.VERIFICATION
API
Create event
resp = client.create_event(CreateEventRequest(
verb=Verb.JUDGMENT.value,
who="did:example:agent",
what="sha256:...",
))
Verify event
result = client.verify_event({
"event": resp.event.to_dict(),
"mode": "archival",
})
Convenience helpers
client.judgment("did:example:agent", what)
client.delegation("did:example:agent", what)
client.termination("did:example:agent", what, ref="sha256:parent")
client.verification("did:example:agent", what, ref="sha256:parent")
Health
health = client.health()
Testing
pytest -q
Tests use a local in-process HTTP server and do not require a live JEP API.

Validation results expose conformance_class from the API. This field may be absent (empty in Python/Go) with older servers; it is never inferred as proof of conformance. Diagnostic maps preserve code, message, level, and recoverable.
