StableOps Python SDK

中文文档

StableOps turns on-chain stablecoin transfers into familiar payment primitives: payment orders, deterministic status transitions, signed webhooks, retries, and confirmation tracking. StableOps watches supported chains, matches transfers, tracks confirmations, checks reorgs, and delivers webhook events to your app.

This SDK is for server-side Python applications that create payment orders and checkout sessions, manage merchant subscriptions, manage webhook endpoints, and verify webhook signatures.

Features

Type-safe client (Pydantic v2 models) for payment orders, checkout sessions, merchant subscriptions, and webhooks.
Sync (StableOps) and async (AsyncStableOps) clients with an identical API.
Built-in request retries and explicit idempotency for write operations.
Constant-time webhook signature verification.

Requirements

Python 3.8 or newer.
A StableOps API key.
A server-side environment. Do not expose your API key in browser code.

Installation

pip install stableops

Quick Start

import os

from stableops import StableOps

client = StableOps(api_key=os.environ["STABLEOPS_API_KEY"])

order = client.payment_orders.create(
    merchant_order_id="order_123",
    amount="49.00",
    accepted_assets=[
        {"chain": "base", "asset": "USDC"},
        {"chain": "tron", "asset": "USDT"},
    ],
    expires_at="2026-12-31T23:59:59Z",
)

print(order.payment_instructions)

The environment (sandbox / live) is determined by the API key prefix (sk_sandbox_… / sk_live_…). Return only the order id, amount, and payment_instructions to your frontend; the API key stays on your server.
