Generate Lightning Invoices with 3 Lines of Python (Coinos API)

Want to accept Lightning payments in your Python app? No node needed. Just Coinos.

3 Lines

import urllib.request, json

data = json.dumps({"invoice": {"amount": 1000, "currency": "SAT", "memo": "Coffee"}}).encode()
req = urllib.request.Request("https://coinos.io/api/invoice", data=data,
    headers={"Authorization": "Bearer YOUR_TOKEN", "Content-Type": "application/json"})
invoice = json.load(urllib.request.urlopen(req))
print(invoice["text"])  # lnbc10u1pn...

That's it. Real Lightning invoice. Payable by any wallet.

Setup (2 minutes)

1. Sign up at coinos.io
2. Go to Settings → API → Generate token
3. Use the token in your Authorization header

No KYC for small amounts. No node to run. No channels to manage.

Full Payment Flow

import urllib.request, json, time

COINOS_TOKEN = "your_token_here"

def create_invoice(amount_sats, memo="Payment"):
    data = json.dumps({"invoice": {
        "amount": amount_sats,
        "currency": "SAT",
        "memo": memo
    }}).encode()
    req = urllib.request.Request(
        "https://coinos.io/api/invoice",
        data=data,
        headers={
            "Authorization": f"Bearer {COINOS_TOKEN}",
            "Content-Type": "application/json"
        }
    )
    return json.load(urllib.request.urlopen(req, timeout=10))

def check_balance():
    req = urllib.request.Request(
        "https://coinos.io/api/me",
        headers={"Authorization": f"Bearer {COINOS_TOKEN}"}
    )
    me = json.load(urllib.request.urlopen(req, timeout=10))
    return me["balance"]

# Create invoice
inv = create_invoice(500, "Widget purchase")
print(f"Pay this invoice: {inv['text']}")
print(f"Amount: {inv['amount']} sats")

# Check if paid (poll balance)
initial = check_balance()
print(f"Current balance: {initial} sats")
# ... wait for payment ...
# new_balance = check_balance()
# if new_balance > initial: print("Paid!")

Use Cases

• Tip jars — embed in your blog/app
• API monetization — charge per request
• Nostr bots — accept payments via DMs
• Micropayments — paywall individual pieces of content
• Donations — accept Bitcoin without running infrastructure

Coinos vs Running Your Own Node

	Coinos API	Own Node (LND/CLN)
Setup time	2 min	Hours/days
Cost	Free	Server + channels
Custody	Custodial	Self-custody
Reliability	Their infra	Your problem
Max amount	Good for small	Unlimited

For prototyping and small amounts, Coinos wins. For production with large volumes, run your own node.

Lightning Address

Every Coinos account gets a Lightning address: [e-mail]. Anyone can send you sats without an invoice — just like email.
