The old way vs the API way

The old way

Call your broker. Wait.

Call or email a freight broker. Describe your shipment. Wait 30 minutes to 4 hours for a rate. Get a quote that does not include fuel surcharges, accessorials, or terminal handling. Ask for a breakdown. Wait again. Compare across 2 or 3 brokers manually. Copy the rate into a spreadsheet. Repeat for every lane, every week.

The API way

One POST. Instant rate.

Send a POST request with origin, destination, pickup date, and item details. Get back an all inclusive rate in under 2 seconds. The rate includes everything: pickup, handling, line haul, delivery. No fuel surcharges. No hidden fees. Compare modes programmatically. Book with the quoteId. Done.

The complete quote request

Every rate request goes to POST https://www.wearewarp.com/api/v1/freight/quote. Authentication is a single header: Authorization: Bearer wak_live_YOUR_KEY. Here is a complete request with every field explained.

  }

const { quotes } = await response.json();
const quote = quotes[0];
console.log(`Rate: $${quote.rate}, Transit: ${quote.transitDays} days`);

Compare rates across modes

One of the most powerful things about the Warp rate API is the ability to compare LTL, box truck, and full truckload rates for the same shipment programmatically. Make three requests with different vehicle types and pick the best option based on cost, transit time, or both. No broker needed for this comparison. Your code does it in seconds.

Python: Compare LTL vs box truck vs dry van

import requests

API_KEY = "wak_live_YOUR_KEY"
BASE = "https://www.wearewarp.com/api/v1"
HEADERS = {"Content-Type": "application/json", "Authorization": f"Bearer {API_KEY}"}

base_payload = {
    "pickupZip": "90001",
    "deliveryZip": "60601",
    "pickupDate": "2026-04-10",
    "pallets": 6,
    "weightPerPallet": 900
}

# Quote LTL
ltl = requests.post(f"${BASE}/freight/quote", headers=HEADERS,
    json={**base_payload, "mode": "LTL"}).json()["quotes"][0]

# Quote FTL (26ft box truck)
box_truck = requests.post(f"${BASE}/freight/quote", headers=HEADERS,
    json={**base_payload, "mode": "BOX_TRUCK"}).json()["quotes"][0]

# Quote FTL (53ft dry van)
ftl = requests.post(f"${BASE}/freight/quote", headers=HEADERS,
    json={**base_payload, "mode": "FTL"}).json()["quotes"][0]

print("LTL:       $" + str(ltl["rate"]) + "  (" + str(ltl["transitDays"]) + " days)")
print("Box Truck: $" + str(box_truck["rate"]) + "  (" + str(box_truck["transitDays"]) + " days)")
print("FTL:       $" + str(ftl["rate"]) + "  (" + str(ftl["transitDays"]) + " days)")

# Pick the cheapest
best = min([ltl, box_truck, ftl], key=lambda x: x["rate"])
print("Best option: " + best["carrier"] + " at $" + str(best["rate"]))

Handling accessorials

Traditional freight quoting treats accessorials as post hoc surprises. You get a rate, book it, then discover you owe an extra $150 for liftgate and $75 for a delivery appointment. Warp prices approved service requirements before dispatch so the shipment economics stay clear. Public self-serve quote requests should use the documented base fields first; confirm account-enabled service options before building accessorial logic.

Pickup services

Add at quote time

Liftgate pickup, inside pickup, residential pickup, limited access, appointment, driver assist, drop and hook, construction site, convention/trade show.

Delivery services

Priced in the quote

Liftgate delivery, inside delivery, residential delivery, limited access, appointment, driver assist, drop and hook, construction site, redelivery.

Additional services

No surprise fees

Sort and seg, extra stop, extra miles, driver assist, white glove, check calls, notification, photo required.

Temperature controlled freight rates

For food, beverage, pharma, or any temperature sensitive freight, Warp can support temperature controlled equipment through approved-account workflows. Confirm that surface before treating temperature requirements as public self-serve fields in a production integration.

Using rate data for cost optimization

Because every rate request and response is structured data, you can build cost optimization logic on top of the Warp API. Compare rates across pickup dates to find the cheapest day to ship. Compare vehicle types for the same lane to see when LTL beats a dedicated box truck. Track rate trends over time by storing quote history. Account-level quote history is available only on enabled account surfaces; confirm the current API reference before building analytics around it.

For recurring lanes, contact the Warp team about custom rate cards. Warp builds rate sheets for high volume shippers with committed capacity and consistent pricing through the Work Queue system, which assigns dedicated carriers to your routes.
