Python SDK

The Python SDK simplifies interacting with the Sindri API.

Installation​

info

Some features of the SDK require a Python version of 3.10 or above. You may encounter difficulty installing the package with older Python versions.

The Sindri Python SDK simplifies interacting with the Sindri API. You can easily install it with pip.

pip install sindri

module sindri.py

Usage​

# Download some sample data
# git clone https://github.com/Sindri-Labs/sindri-resources.git

# pip install sindri
from sindri import Sindri

# Initialize
sindri = Sindri("<YOUR_API_KEY>", verbose_level=2)

# Upload a Circuit
circuit_upload_path: str = "sindri-resources/circuit_database/circom/multiplier2"
circuit_id: str = sindri.create_circuit(circuit_upload_path)

# Generate a Proof
proof_input_file_path = "sindri-resources/circuit_database/circom/multiplier2/input.json"
with open(proof_input_file_path, "r") as f:
     proof_id: str = sindri.prove_circuit(circuit_id, f.read())
