py-gasbuddy 0.6.0

Python wrapper for GasBuddy GraphQL API

py-gasbuddy

Python async library for retrieving gas station data from the GasBuddy GraphQL API.

Provides three query methods covering single-station detail (prices, hours, amenities, offers), location-based station search, and a price-service query that returns prices plus regional trend data for nearby stations.

---

Installation

pip install py-gasbuddy

---

Quick Start

import asyncio
from py_gasbuddy import GasBuddy

async def main():
    gb = GasBuddy(station_id=205033)
    data = await gb.price_lookup()
    print(data["name"], data["regular_gas"]["price"])

asyncio.run(main())

GasBuddy Class

GasBuddy(
    station_id: int | None = None,
    solver_url: str | None = None,
    cache_file: str = "",
    timeout: int = 60000,
    session: aiohttp.ClientSession | None = None,
)

Parameter	Description
station_id	GasBuddy station ID — required for price_lookup()
solver_url	URL of a FlareSolver instance for Cloudflare bypass
cache_file	Path for the CSRF-token cache file (default: py_gasbuddy/gasbuddy_cache)
timeout	Request timeout in milliseconds (default: 60000)
session	Optional aiohttp.ClientSession to reuse — caller manages lifecycle

Cloudflare / FlareSolver

GasBuddy's homepage is protected by Cloudflare. The library extracts a CSRF token from the HTML before making GraphQL requests. If the direct fetch fails, pass a solver_url pointing to a running FlareSolver instance:

gb = GasBuddy(station_id=205033, solver_url="http://localhost:8191/v1")

Tokens are cached on disk to avoid redundant solver calls across restarts.

Methods

price_lookup() → StationPrice

Returns full detail for a single station including prices, hours, amenities, brand, and offers. Requires station_id to be set at construction time.

gb = GasBuddy(station_id=205033)
data = await gb.price_lookup()

# Station metadata
print(data["name"])           # "Wawa"
print(data["phone"])          # "610-555-0100"
print(data["open_status"])    # "open"
print(data["star_rating"])    # 4.2
print(data["ratings_count"])  # 38
print(data["pay_status"])     # True (GasBuddy Pay available)
print(data["fuels"])          # ["regular_gas", "midgrade_gas", "premium_gas"]

# Address
print(data["address"]["line1"])    # "123 Main St"
print(data["address"]["locality"]) # "Phoenixville"
print(data["address"]["region"])   # "PA"

# Brands
if data["brands"]:
    print(data["brands"][0]["name"])     # "Shell"
    print(data["brands"][0]["imageUrl"]) # logo URL

# Hours
print(data["hours"]["status"])       # "open"
print(data["hours"]["openingHours"]) # "24 Hours"

# Prices (credit and cash)
reg = data["regular_gas"]
print(reg["price"])           # 3.27  (credit price)
print(reg["cash_price"])      # 3.17  (None if not reported)
print(reg["formatted_price"]) # "$3.27"
print(reg["last_updated"])    # "2024-09-06T09:54:05Z"
print(reg["credit"])          # reporter nickname

# Emergency status (fuel/power outage reports)
print(data["emergency_status"]["hasGas"]["reportStatus"])  # None or "has_gas"

# Loyalty offers
for offer in data["offers"]:
    print(offer["id"], offer["types"], offer["use"])

# Amenities
for amenity in data["amenities"]:
    print(amenity["name"])  # "ATM", "Restrooms", etc.

Fuel product keys are dynamic and match whatever the station reports: regular_gas, midgrade_gas, premium_gas, diesel, e85, e15, etc.

---

location_search(lat, lon, zipcode, brand_id, fuel, cursor) → LocationSearchResult

Returns a dict with results (list of StationSummary) and optionally next_cursor for pagination. Pass either lat+lon or zipcode.

# By ZIP code
result = await GasBuddy().location_search(zipcode=85396)

# By GPS coordinates
result = await GasBuddy().location_search(lat=33.465, lon=-112.505)

# Filter to diesel-only stations (fuel ID 4)
result = await GasBuddy().location_search(zipcode=85396, fuel=4)

# Filter to a specific brand (38 = Costco)
result = await GasBuddy().location_search(zipcode=85396, brand_id=38)

for s in result["results"]:
    print(s["station_id"], s["name"], s["distance"])
    print(s["address"]["locality"], s["address"]["region"])
    print(s["fuels"])

# Paginate
cursor = result.get("next_cursor")
if cursor:
    page2 = await GasBuddy().location_search(zipcode=85396, cursor=cursor)

StationSummary fields:

Field	Type	Description
station_id	str	GasBuddy station identifier
name	str	Station/brand display name
address	Address	line1, line2, locality, region, postalCode, country
brands	list[Brand]	Brand name, brandId, logo imageUrl
distance	float | None	Distance from search point (miles)
star_rating	float | None	Community star rating
ratings_count	int | None	Number of ratings
fuels	list[str]	Fuel products sold
price_unit	str | None	"dollars_per_gallon" or "cents_per_liter"

---

price_lookup_service(lat, lon, zipcode, limit, brand_id, fuel, cursor) → PriceServiceResult

Returns prices for nearby stations plus regional trend data. Pass either lat+lon or zipcode. limit defaults to 5.

result = await GasBuddy().price_lookup_service(zipcode=85396, limit=10)

for station in result["results"]:
    print(station["name"], station["distance"])
    if "regular_gas" in station:
        print(station["regular_gas"]["price"])
        print(station["regular_gas"]["formatted_price"])

# Regional trends
for trend in result.get("trend", []):
    print(trend["area"], trend["average_price"], trend["lowest_price"])

# Paginate
cursor = result.get("next_cursor")
if cursor:
    page2 = await GasBuddy().price_lookup_service(zipcode=85396, cursor=cursor)

Results have the same structure as StationPrice (see price_lookup above) minus station-only fields like amenities, hours, offers, and pay_status.

Fuel Types

Filter ID	Product key	Description
1	regular_gas	Regular (85-87 Octane)
2	midgrade_gas	Mid-Grade (89 Octane)
3	premium_gas	Premium (91-93 Octane)
4	diesel	Diesel
5	e85	E85
12	unl88	Unleaded 88 (E15)

The filter ID is the integer passed to the fuel parameter on location_search and price_lookup_service. The product key is the string used as a dictionary key in StationPrice results (e.g. data["regular_gas"]). Both are also available as FUEL_FILTER_IDS and FUEL_PRODUCTS in py_gasbuddy.consts.

---

Data Models

All return types are TypedDict subclasses defined in py_gasbuddy.models.

PriceNode

class PriceNode(TypedDict):
    credit: str | None          # reporter nickname
    price: float | None         # credit price (None = not reported)
    cash_price: float | None    # cash price (None = not reported)
    last_updated: str | None    # ISO 8601 timestamp
    formatted_price: str | None # "$3.27" or "131.9¢"
    deal_price: float | None    # price after GasBuddy Pay discount (None if no offer or no price)

deal_price is computed from the pwgbDiscount field returned by the GasBuddy GraphQL API, which covers the Flash Deal and GasBuddy+ Member Savings components. The Card Savings Boost (available to GasBuddy+ members who select Fleet Card at the pump) is sourced from the mobile REST API and is not included here, so deal_price may be slightly higher than what the GasBuddy app displays for GasBuddy+ members.

TrendData

class TrendData(TypedDict):
    area: str            # "Arizona" or "United States"
    average_price: float # today's average
    lowest_price: float  # today's lowest (0 if not available)

---

Error Handling

Exception	Raised when
MissingSearchData	location_search or price_lookup_service called without coordinates or ZIP
LibraryError	Network or parse error; check logs for details
APIError	GasBuddy's GraphQL returned an errors field

from py_gasbuddy.exceptions import APIError, LibraryError, MissingSearchData

try:
    data = await gb.price_lookup()
except LibraryError:
    print("Network or token error")
except APIError:
    print("GasBuddy API error")

---

Cache Management

# Clear the cached CSRF token (forces a fresh fetch on next request)
await gb.clear_cache()

---
