Compare State Gas Prices for Travel Cost Planning

Export AAA state gas averages as JSON to estimate road-trip fuel costs per leg — where to fill up, and what the trip will actually cost.

TL;DR — The Fuel Prices Scraper exports AAA's per-state gas averages as JSON. Compare the states on your route, plan fills on the cheap side of borders, and price the trip on the day's actual data.

Why fuel stops are a planning decision

Interstate price gaps are structural — taxes, formulations, distance from supply. A route through five states crosses five different fuel markets, and the difference between filling in one versus the next is real money over a long trip.

The job-to-be-done: a current per-state table, joined to your route, that answers "where should I buy."

How does this compare to the alternatives?

Gas apps while driving AAA trip planner Thirdwatch actor
Cost Free Free Pay per result
Reliability Pump-level, live Route guidance State-level benchmark
Setup time Zero Per trip Minutes
Maintenance In-car decisions Manual Scheduled refresh

Pump-level apps win in the moment. For pre-trip budgeting and recurring route costing, a state-level data pull is the right grain.

How to compare in 4 steps

How do I pull my route's states?

import os
from apify_client import ApifyClient

client = ApifyClient(os.environ["APIFY_TOKEN"])
run = client.actor("thirdwatch/fuel-prices-scraper").call(
    run_input={"states": ["nevada", "california", "oregon", "arizona", "utah"]}
)
rows = list(client.dataset(run["defaultDatasetId"]).iterate_items())

How do I rank the fill stops?

import pandas as pd
df = pd.DataFrame(rows)
print(df[["region", "regular", "diesel"]].sort_values("regular"))

Cheapest first — those are your planned fill states.

How do I estimate the trip cost?

MPG, TANK = 28, 15
legs = {"nevada": 300, "california": 450, "oregon": 250}  # miles per state
cost = sum(m / MPG * df.set_index("region").loc[s.title(), "regular"]
           for s, m in legs.items())
print(f"Estimated fuel cost: ${cost:.0f}")

How do I keep estimates honest?

Refresh the pull the week of departure — week_ago and month_ago columns show whether prices are rising or stable, so you know if today's estimate will hold.

Sample output

{"region": "Arizona", "scope": "state:az", "date": "2026-09-21",
 "regular": 3.55, "mid_grade": 3.84, "premium": 4.10,
 "diesel": 3.72, "e85": 2.91,
 "yesterday": 3.54, "week_ago": 3.50, "month_ago": 3.62, "year_ago": 3.48}

Common pitfalls

State averages mask metro premiums — resort and urban areas run above the mean. Border-town stations know their advantage; the average understates what you'll actually pay at the convenient stop. Prices move daily — refresh close to departure. The actor supplies the comparison; the detour math stays yours.

Frequently asked questions

How much can state choice save on a trip?

State averages routinely differ by over a dollar per gallon — a 15-gallon fill on the cheap side of a border saves $15+ per stop. The records give you the per-state number to plan around.

Does the actor cover all 50 states?

Yes — every state AAA publishes, plus the national average row. List specific states or leave it empty for national only.

How current is the comparison?

AAA updates daily. The record's date field tells you exactly which day's fix you're comparing.

Can I get diesel or premium instead of regular?

Each record carries all published grades — regular, mid_grade, premium, diesel, e85 — so compare whatever your vehicle burns.
