yatmo

Add real estate maps, points of interest and neighbourhood data to Python applications. yatmo is the official Python client for the Yatmo API: the written neighbourhood text of a property (rendered as HTML on the server, so search engines index it), the nearest schools, nurseries, supermarkets and public transport with real travel times, scores, listing enrichment, isochrones, routes, geocoding and static map images, in 25 countries and 23 languages. Works with Django, Flask, FastAPI, notebooks and scripts, Python 3.9 and later, no dependency.

pip install yatmo

from yatmo import Client, TravelMode, render_html

yatmo = Client(key="your_backend_key", country="BE", language="FR")

# The neighbourhood text as HTML, to write into the property page.
text = yatmo.summary_text(50.8461, 4.3664)
print(render_html(text))
# <div class="yatmo-text"><h3>Commerces près de la Rue de la Loi</h3><p>Un <strong>Carrefour</strong> à 3 minutes...

# The nearest places by category with walking times.
summary = yatmo.summary(50.8461, 4.3664)
for sub in summary.sub_categories():
    place = sub.places[0] if sub.places else None
    walk = place.travel(TravelMode.WALKING) if place else None
    print(sub.label, ":", place.name if place else "-", walk.travel_time_short_label if walk else "")

Install in 5 minutes

1. Get a Yatmo licence key at yatmo.com and use the backend key on the server (keys explained).
2. pip install yatmo.
3. Create one Client per country, call summary_text() and summary() for each property, cache the answers (a neighbourhood rarely changes; summary_text_raw() and summary_raw() return plain dicts for that) and write the HTML into the page.

Runnable example: examples/property_page.py. The interactive map itself is an iframe with your frontend key, no Python needed: iframe plugin.

Client

yatmo = Client(
    key="your_backend_key",
    country="BE",                 # the API host is https://be.yatmo.com/
    language="FR",                # labels and texts, default EN
    transport=None,               # optional: any object with get(url, headers, timeout_seconds) -> (status, body)
    timeout_seconds=15,
)

Errors are typed: BadRequestError (400, position outside the country), AuthenticationError (401), ForbiddenError (403, country or endpoint not in the licence), QuotaError (429), TransportError (unreachable), all subclasses of YatmoError with a status.

Rendering the text

render_html(text, heading="h3", titles="street-city", paragraphs=None, strong=True, css_class="")
render_markdown(text, titles="street-city", paragraphs=None, strong=True)
render_plain(text, titles="street-city", paragraphs=None)

titles: the first heading names the street and the second the city ("street-city"), the city only ("city", for discreet listings) or neither ("generic"). paragraphs keeps some icon ids only among education, shopping, publictransports, transports, tourism, cities.

Django, Flask, FastAPI

# Django view
from django.core.cache import cache

def listing(request, pk):
    listing = Listing.objects.get(pk=pk)
    key = f"yatmo-text-{listing.latitude:.6f}-{listing.longitude:.6f}"
    raw = cache.get(key)
    if raw is None:
        raw = yatmo.summary_text_raw(listing.latitude, listing.longitude)
        cache.set(key, raw, 30 * 86400)
    neighbourhood = render_html(SummaryText.from_wire(raw, request.LANGUAGE_CODE))
    return render(request, "listing.html", {"listing": listing, "neighbourhood": neighbourhood})

In the template: {{ neighbourhood|safe }} below the map iframe.

Tests

python -m unittest discover tests                       # hermetic, the API is faked
YATMO_LIVE_KEY=your_backend_key python -m unittest tests.test_live   # one real call per endpoint
