plures

The official Python client for Plures: human judgment as an API for AI agents. Send a decision to ID verified people and get their consensus back before your agent acts. A human in the loop step you can call like any other API.

pip install plures

Python 3.8+, standard library only.

Use it

from plures import Plures

plures = Plures()  # reads PLURES_API_KEY, or Plures("pk_test_...")

task = plures.verify(
    "Does the invoice match the order?",
    ["Matches", "Does not match"],
    context="Order: 48 chairs, $4,218. Invoice: 48 chairs plus $180 freight, $4,398.",
    verifiers=3,
)
result = task["result"]
if result and result["agreement"] == 1:
    print("Act on:", result["answer"])
else:
    print("Not unanimous: send to the team")

Get a free test key at plures.si. Test keys complete at once with the first option (or metadata["test_answer"]) and never reach real people. Set metadata["test_outcome"] to split, tie, expired or slow to test the cases you route to your own team.

Production: webhooks

plures.create_task(
    "Should this customer get a refund?", ["Approve", "Decline"],
    context=ticket_text, webhook_url="https://your.app/plures",
    metadata={"order_id": order_id}, idempotency_key="refund-%s" % order_id,
)

# In your webhook handler (Flask shown), pass the raw body exactly as received
from plures import verify_webhook
event = verify_webhook(request.get_data(), request.headers.get("Plures-Signature"), WEBHOOK_SECRET)

API

• create_task(question, options, idempotency_key=None, **fields): fields are context, image_url, instructions, verifiers (1, 3, 5, 7 or 9), max_verifiers, presence_check (default True), webhook_url, metadata, expires_in
• get_task(id), list_tasks(status=None, limit=None, starting_after=None), cancel_task(id)
• wait_for(id, timeout=600, interval=3): poll until settled
• verify(question, options, timeout=600, **fields): create and wait
• verify_webhook(raw_body, signature_header, secret): check a webhook and return the event

Errors raise PluresError with .status and .type. Server errors are retried twice.
