trustmrr 🐍💸

A Python client for the TrustMRR API,
for people who like their startup data the way they like their coffee:
strong, typed, and delivered in cents.

---

What is this? 🤔

You want to know which startups are on sale. You want to know their MRR, their multiples, their vibes. You want it in Python. You do not want to write requests.get(...) for the seventeenth time this week.

This library does that. You're welcome.

Install 📦

pip install trustmrr

That's it. No build step. No native deps. No "first install Rust." It's 2026 and we're not animals.

60-second quickstart ⏱️

from trustmrr import TrustMRRClient

client = TrustMRRClient(api_key="tmrr_your_api_key")  # don't commit this. don't.

deals = client.list_startups(sort="best-deal", on_sale=True, limit=5)

for s in deals["data"]:
    print(f"{s['slug']:20} MRR ${s['revenue']['mrr']/100:>10,.2f}  multiple {s['multiple']}x")

Output (your numbers will vary, theirs always do):

acmehq               MRR $  35,000.00  multiple 3.2x
widgetco             MRR $  18,420.00  multiple 2.7x
...

Pagination, the lazy way 😴

You could write a while True: with a page counter and a hasMore check. Or you could not.

for startup in client.iter_startups(category="SaaS", min_mrr=100_000):
    print(startup["slug"])

iter_startups yields rows forever until the API politely says "I have no more startups for you." It will then stop. Generators: still good.

All the knobs 🎛️

Every parameter is keyword-only and optional. Set what you need, ignore the rest.

Knob	Type	What it does
page	int	Page number (≥ 1). For when you're feeling sequential.
limit	int	1–50. The API draws the line at 50. We agree with the API.
sort	str	One of: revenue-desc, revenue-asc, price-desc, price-asc, multiple-asc, multiple-desc, growth-desc, growth-asc, listed-desc, listed-asc, best-deal.
on_sale	bool	True for "show me the bargain bin."
category	str	"SaaS", "AI", "fintech", and 20 friends.
x_handle	str	Founder's X/Twitter handle. Skip the @, we'll know.
min_revenue / max_revenue	number	Last-30-day revenue, in cents.
min_mrr / max_mrr	number	MRR, in cents.
min_growth / max_growth	number	Decimal. 0.1 = 10%. 1.0 = "are you sure?"
min_price / max_price	number	Asking price, in cents.

💡 Everything monetary is in cents. 42500 means $425.00. Yes, we checked. Twice. Divide by 100 before showing it to humans.

When things go sideways 💥

Non-2xx responses raise TrustMRRError. It has a .status_code and a .payload, both of which are nicer than a generic requests.HTTPError.

from trustmrr import TrustMRRError

try:
    client.list_startups()
except TrustMRRError as e:
    if e.status_code == 401:
        print("Your key is wrong, or expired, or imaginary.")
    else:
        print(f"API said {e.status_code}: {e.payload}")

Wait, where do I get an API key? 🔑

trustmrr.com. Then read the API docs for the source of truth on parameters and response shape. (This README is the friendly tour; the docs are the legal text.)

Development 🛠️

git clone https://github.com/SergeySetti/trustmrr-python.git
cd trustmrr-python
pip install -e ".[test]"
pytest

All tests are offline — HTTP is mocked, your wallet is safe.
