A quick look at how eu_delivery and eu_warehouse shape the score and what that means for your next product pick
THE REAL COST OF GUESSING
You spend hours researching a product, you check the margin, you glance at the price point, and you feel ready to order. Then a few weeks later the shipment sits in customs, the delivery date slips, and your ad budget burns while you wait for stock. That sinking feeling isn’t just about late packages. it’s about money you could have kept if you had known earlier whether the product could actually reach your EU customers in time.
The O-Score API was built to turn that guesswork into a clear number. It doesn’t just add up margins and price points; it weighs how fast the item can get to your door and whether it’s stored locally in the EU. Those two pieces. eu_delivery and eu_warehouse. are not optional details. They are hard requirements that can push a product from “maybe” to “avoid” in a single score.
WHAT EU_DELIVERY AND EU_WAREHOUSE ACTUALLY MEASURE
When you call the O-Score endpoint you receive five component scores: margin, eu_delivery, eu_warehouse, price_point, and risk. Each component is normalized to a 0-100 scale before being combined into the final score.
eu_delivery looks at the typical transit time from the supplier’s location to the EU border. If the supplier ships from outside the EU and the average delivery exceeds 10 days, the component drops sharply. Faster shipments. think 3-5 days from an EU-based warehouse. keep the eu_delivery score high. The metric is binary in spirit: either the product can realistically reach your customers within the window you need, or it cannot.
eu_warehouse checks whether the supplier holds inventory inside the EU. Stock held locally means you avoid customs delays, you reduce the chance of lost parcels, and you can promise faster delivery to your buyers. If the supplier has no EU warehouse, the eu_warehouse component receives a low penalty, reflecting the added risk of longer lead times and potential holdups.
Both components are weighted equally with the other three factors. A weak eu_delivery or eu_warehouse score drags the total down, even if your margin looks fantastic and the price point is attractive.
HOW THE SCORE BUILDS FROM THESE PARTS
The final O-Score is a simple sum of the five normalized components, then scaled to 0-100. Because each component contributes equally, a low score in eu_delivery or eu_warehouse can offset a high margin. For example, a product with a 90 margin score but a 30 eu_delivery score and a 20 eu_warehouse score will end up far below the threshold for a strong candidate.
The API returns four verdicts based on the total:
* STRONG CANDIDATE. score 75 or higher
* CANDIDATE. score 60 to 74
* MARGINAL. score 45 to 59
* AVOID. score below 45
If you are aiming for a product you can confidently advertise and sell, you need at least a CANDIDATE rating. Anything lower means you are likely to lose money on delayed shipments, increased customer service costs, or wasted ad spend.
WHAT THE VERDICTS MEAN FOR YOUR WALLET
Imagine you pick a product that scores 70. a CANDIDATE. You move forward, run a test ad campaign, and the item arrives in five days because the supplier ships from an EU warehouse. Your ads convert, you keep your margin, and you avoid the dreaded “out of stock” message.
Now imagine you ignored the eu_delivery and eu_warehouse signals and chose a product that scored 40. an AVOID. The same ad spend brings clicks, but the shipment takes three weeks, customers cancel, you issue refunds, and your profit evaporates. The difference between those two outcomes is often just a few points in the eu_delivery and eu_warehouse components.
Because the free tier gives you 25 scores per month, you can test a handful of product ideas without spending a cent. Each call tells you instantly whether the EU logistics side will support your business model or undermine it.
TURNING INSIGHT INTO ACTION
Start by listing the products you are considering. For each one, make a quick O-Score call. Look at the breakdown: if eu_delivery or eu_warehouse is below 50, treat that as a red flag. You don’t need to be a data scientist to see the pattern. the API does the heavy lifting.
If a product fails the EU logistics test, you have two options: look for an alternative supplier with EU stock, or move on to another idea. Either way you save yourself the headache of delayed shipments and the cost of wasted advertising.
When you find a product that scores in the CANDIDATE or STRONG CANDIDATE range, you can proceed with confidence, knowing the delivery side is already accounted for.
