Vehicle Marketplaces

Every listing verified before a buyer sees it

GoodToKnow lets used vehicle marketplaces run automated VIN checks on every listing submission. Surface odometer anomalies, active finance, and total loss category at intake, before publication.

Listing intake verification

Run an automated verification check when a seller submits a listing. Flagged vehicles can be held for manual review before publication.

Mileage consistency verification

Declared mileage is cross-checked against MOT records and service history entries. Inconsistencies are flagged with confidence scores.

Finance encumbrance check

Identify vehicles with outstanding finance agreements before listing. Protects buyers and reduces your platform liability for undisclosed encumbrances.

Residual value banding

Registry-informed residual value band at time of listing provides a reference for pricing guidance tools and partner lender integrations.

Use Case

Automated verification at listing submission

When a seller submits a vehicle listing, your platform calls GoodToKnow. The response returns in time to gate or flag the listing before it enters the moderation queue.

Seller submits listing

Seller enters VIN or registration plate alongside declared mileage, asking price, and listing category. Your platform captures the VIN for verification.

Asynchronous verification

Your intake service calls the GoodToKnow API with the VIN and country code. Single-VIN responses return within 500ms. Batch mode handles bulk re-verification of existing inventory.

Signals gate publication

Your listing rules engine reads the signal set. Clean verification can auto-publish. Flagged signals route to moderation queue. A verified badge can be surfaced to buyers on clean listings.

Platform Value

Why verification changes marketplace trust economics

Marketplace fraud at listing level erodes buyer confidence and concentrates liability at platform level. Registry-backed verification addresses the problem at intake.

Buyer trust through verified listings

Verified vehicle history badges at listing level convert browsers into buyers. Registry-backed verification carries more credibility than seller-uploaded documents.

Reduced platform liability

Systematic verification at intake reduces exposure to disputes from buyers who discover undisclosed finance, odometer manipulation, or total loss category after purchase.

Lender partnership enablement

Finance partners require vehicle history assurance before approving lending against inventory. Consistent GoodToKnow verification simplifies the data requirement for lender integrations.
