You need to show gas prices for a specific U.S. ZIP code in your app this week, prove it works in Postman, and ship. By the end of this article, you’ll query real station prices by ZIP and fuel type with the Gas Prices in USA by ZIP Code API from Zyla API Hub, parse the response in code, and understand how to pull station details when you have an ID.
What this API does and when to use it
The Gas Prices in USA by ZIP Code API returns the latest fuel prices for stations in a given U.S. ZIP code and fuel type. It’s designed for developer workflows where you need quick price lookups to power budgeting, cost comparisons, or checkout flows (e.g., estimating fuel cost for delivery, rideshare, or fleet routing). The response includes:
- ZIP and gas type context
- Currency
- Aggregates (average, lowest) and per-station entries (name, address, price)
Typical use cases include:
- Consumer price comparison widgets showing the cheapest regular gas near a location
- Finance and ops tools estimating trip costs based on local fuel prices
- Expense and budgeting apps forecasting monthly fuel spend per driver ZIP
- E-commerce or logistics calculators surfacing real-time fuel surcharges by ZIP
The API is available on Zyla API Hub, a marketplace with more than 10,000 public APIs under a subscription + quota model. One account, one key, consistent auth and usage tracking across your stack.
Getting started on Zyla API Hub
To call this API, open the listing page on Zyla API Hub, click Subscribe (or Start Free Trial when available), and obtain your API key. Zyla uses subscription + quota billing (not pay-per-call). There is no Free Plan. For a first API, you’ll typically see a 7-day trial or 50 requests option—check the API page for current access options and pricing.
Authentication is the same across calls: include your key in the Authorization header as Bearer YOUR_API_KEY.
Endpoints you can call
This API exposes two endpoints through the Hub. The Get Prices endpoint is what you’ll use to query prices by ZIP and fuel type. When you need deeper station details, use Station Data with a station ID you obtained via Get Prices.
1) Get Prices
- Method: GET
- URL: https://zylalabs.com/api/4805/gas-prices-in-usa-by-zip-code/5987/get-prices
- Description: Pass the ZIP code of your choice and the type of fuel that you want to check into. The API returns prices for relevant gas stations in the given ZIP.
- Query parameters:
- zip (number, required): e.g., 90002
- type (string, required): e.g., regular
Copy-pasteable curl (official sample):
curl -s -X GET "https://zylalabs.com/api/4805/gas-prices-in-usa-by-zip-code/5987/get-prices?zip=90002&type=regular" \

}What to read from this payload:
- status: success indicator string
- zip: ZIP code context (string)
- gas_type: fuel type you requested (e.g., regular)
- currency: USD
- gas_prices: an array that starts with aggregates (average, lowest) followed by station-level entries (station, address, price)
Units and formatting: prices are strings with a leading “$” and represent dollars per gallon. Currency is explicitly USD.
2) Station Data
- Method: GET
- URL: https://zylalabs.com/api/4805/gas-prices-in-usa-by-zip-code/23307/station-data
- Description: Returns details for a single station. You must specify a station ID. You can obtain the ID from the Get Prices endpoint.
- Parameters: none documented on the Hub listing beyond requiring a station ID. Use authorization as shown below.
Note: Because the listing does not document station ID as a query parameter name or path variable, treat this endpoint as “ID-required” at a high level and refer to the API page for how to pass it in your use case. Do not invent parameter names.
Example Station Data response:
This payload provides station metadata you can show in a detail view: standardized address, coordinates, contact info, status, ratings, supported fuels, and nearby stations. Currency and price_unit confirm dollars_per_gallon for pricing context.
Test it quickly in Postman
Step-by-step
- Create a new GET request in Postman.
- Enter the URL:
https://zylalabs.com/api/4805/gas-prices-in-usa-by-zip-code/5987/get-prices?zip=90002&type=regular - In the Headers tab, add:
- Key: Authorization
- Value: Bearer YOUR_API_KEY
- Send the request. You should receive a JSON payload like the official sample above.
Tip: Keep an eye on the “average” and “lowest” entries that appear first in gas_prices. Then, iterate station items for names, addresses, and prices to render a list sorted by price.
Code you can paste into your app
Python (requests) example
This script calls Get Prices for ZIP 90002 and fuel type “regular,” then prints the aggregate prices and the top 3 stations by order of appearance.
import os
import requests
API_KEY = os.getenv("ZYLALABS_API_KEY", "YOUR_API_KEY")
url = "https://zylalabs.com/api/4805/gas-prices-in-usa-by-zip-code/5987/get-prices?zip=90002&type=regular"
headers = {
"Authorization": f"Bearer {API_KEY}"
}
resp = requests.get(url, headers=headers, timeout=30)
resp.raise_for_status()
data = resp.json()
status = data.get("status")
zip_code = data.get("zip")
gas_type = data.get("gas_type")
currency = data.get("currency")
items = data.get("gas_prices", [])
# Extract aggregates from the first element if present
average_price = None
lowest_price = None
if items and "average" in items[0]:
average_price = items[0].get("average")
lowest_price = items[0].get("lowest")
print(f"Status: {status}")
print(f"ZIP: {zip_code} Type: {gas_type} Currency: {currency}")
print(f"Average: {average_price} Lowest: {lowest_price}")
# Iterate station entries (skip the first aggregate item)
stations = items[1:] if items else []
for s in stations[:3]:
name = s.get("station")
addr = s.get("address")
price = s.get("price")
print(f"- {name} | {addr} | {price}")Notes that save you time:
- Prices are strings with currency symbols. If you need numeric comparison, strip “$” and cast to float cautiously.
- The first object in gas_prices contains aggregates; handle it separately from station entries.
- currency is USD. For finance tooling, you can treat this as canonical unit when calculating costs.
Production integration details
- Authentication: Authorization: Bearer YOUR_API_KEY on every request.
- Units: Prices are dollars per gallon. currency is “USD”. price_unit surfaced by Station Data is “dollars_per_gallon”.
- Caching: The listing does not document cache headers or refresh intervals. If you call frequently, consider short-term caching per ZIP and fuel type to reduce redundant requests and latency.
- Pagination: Not documented on the listing. Expect one page per call.
- Timeouts: Set a reasonable client timeout (e.g., 30s in the Python example).
- Error handling: Check status fields in your application logic and handle non-2xx HTTP responses with retries where appropriate.
Finance-first use cases you can ship this week
- Trip estimators: Multiply route distance (mi) by vehicle MPG and the local “average” price to estimate fuel costs per trip or job in checkout.
- Reimbursement policy engines: Validate driver-submitted fuel expenses by comparing against the “lowest” or nearby station prices for that day and ZIP.
- Dynamic surcharges: For delivery or moving services, compute a surcharge indexed to local “average” fuel price for the pickup ZIP at booking time.
- Budgeting dashboards: For each driver’s home ZIP, pull “regular” price weekly and project monthly spend per vehicle class.
Call it from an AI agent via MCP
If you build with AI coding tools (Claude Code, Cursor, Windsurf, or any MCP-compatible client), you can route calls through Zyla’s MCP endpoint. Provide your Zyla API key as a query parameter when you initialize your MCP tool:
Endpoint: https://mcp.zylalabs.com/mcp?apikey=YOUR_API_KEY
See the MCP page for client setup details. The same Authorization: Bearer semantics apply for requests that your agent crafts to the Hub endpoints.
Postman and CI tips
- Environment variables: Store YOUR_API_KEY in an environment and reference it in the Authorization header to avoid copy-paste mistakes across requests.
- ZIP coverage tests: Add one request per market you serve (e.g., 90002, 75201, 33101). Inspect that gas_prices is non-empty.
- Parsing assertions: In Postman tests, assert that currency === "USD" and that the first gas_prices element contains average and lowest keys.
- Mask strings: If you convert price strings to floats, ensure you strip the dollar sign and handle rounding consistently when you display computed totals.
