Read your Stripe revenue from Python

Connect your own Stripe account or Lemon Squeezy store, read only, and ask for the numbers a solo founder checks: MRR, who started paying, who cancelled, and what was collected. It is deliberately small. It is also what lets Launch tell you which waitlist signups became customers.

Keys

Secret key (nv_live_…) on your server only. There is no browser part: revenue and contact data must not reach a page a visitor can read. Create both under Dashboard → API keys.

Publishable key pasted into the page that embeds the form
NORDVA_SECRET_KEY=nv_live_…

01Server: Python

revenue.py

import os
import httpx

res = httpx.get(
    "https://api.nordva.dev/v1/revenue/summary?period_days=30",
    headers={"Authorization": f"Bearer {os.environ['NORDVA_SECRET_KEY']}"},
)
if res.status_code >= 400:
    err = res.json()["error"]
    raise RuntimeError(f"{err['code']}: {err['message']}")
data = res.json()["data"]
for m in data["by_currency"]:
    print(m["currency"], m["mrr_minor"] / 100, "MRR;", m["new_subscriptions"], "new,", m["churned_subscriptions"], "churned")

Amounts are in the smallest currency unit and never converted between currencies. Connect Stripe first, read-only, under Dashboard → Revenue; without a connection the API answers STRIPE_NOT_CONNECTED. Indie and up.

Behaviour worth knowing

  • Every response is { data, error, meta }. On failure error.code is a stable string such as VALIDATION_ERROR, PLAN_LIMIT_REACHED or RATE_LIMITED, with a remediation message.
  • POST and PATCH requests accept an Idempotency-Key header; the same key with the same body returns the original response for 24 hours.
  • Rate limits per key: 30 requests a minute on Free, 120 on Indie, 500 on Builder. A 429 carries Retry-After.
  • Browser calls with a publishable key must come from an origin registered on the project, otherwise the API answers ORIGIN_NOT_ALLOWED.
