Vaultik Opens a Call for Developers and Retail Platforms to Build on Its Authentication APIs

High-value goods are bought and resold across more channels than ever: brand stores, pre-owned marketplaces, auction houses, consignment platforms and social commerce. Every one of these channels faces the same question before a transaction closes: is this item genuine, and what is it worth?

Most platforms still answer that question with manual checks, scattered vendors and slow turnaround times. That creates friction for buyers, risk for sellers and cost for the platform in the middle.

Our APIs were built to make trust a feature that any platform can add to its own product. Opening a call lets us work directly with the teams closest to buyers and sellers, and build integrations that fit how they actually operate.

Developers and product teams building commerce, resale, inventory or collector applications who want to add authentication and valuation inside their own user experience.

Retail platforms and retailers that buy, sell or take back pre-owned handbags and watches and need consistent, documented checks at intake or before listing.

Marketplaces and auction platforms that want to reduce counterfeit listings, speed up item approval and give buyers verified information at the point of sale.

Service providers such as repair, consignment, insurance and logistics partners that handle high-value items and need a reliable record of authenticity and condition.

Authentication at listing: let sellers submit photos of a handbag or watch and receive an authentication result before the item goes live.

Valuation inside the flow: show an indicative market value alongside the result, so sellers can price with confidence and buyers can trust the price.

Digital IDs for verified items: attach a Vaultik Digital ID to each authenticated item, creating a record that follows the product through resale, repair and insurance.

Intake and buy-back tools: give store and warehouse teams a consistent way to check items as they arrive, with a documented result for every decision.

Custom experiences: if your platform has a specific workflow, category focus or brand mix, we can work with you on a tailored integration.

Integration cost is often the main reason good ideas never ship. For selected partners in this call, Vaultik will sponsor the cost of the custom development required to build the integration.

That means our team works alongside yours to scope the integration, design the user flow and deliver the custom work, without the development bill landing on your side.

The scope of sponsorship is agreed with each selected partner individually, based on the project, its timeline and its expected impact.

1. Apply: send a short description of your platform, your users and what you would like to build.

2. Discovery call: we review your use case together and identify where authentication, valuation and Digital IDs add the most value.

3. Scoping: we agree on the integration, the sponsored custom work and a delivery plan.

4. Build: your team gets API access, documentation and direct support from Vaultik engineers while the custom development is delivered.

5. Launch: we help you go live and measure the results with your users.

A clear use case where authentication or valuation solves a real problem for your buyers, sellers or staff.

Meaningful volume of handbags, watches or other high-value items moving through your platform, or a credible plan to get there.

A team ready to work with us on integration and launch.

Applications are reviewed on a rolling basis. Early applicants will be prioritized as sponsored places are limited.

Send an email to pietro@vaultik.com with the subject "Call for Developers – Application". Include your company name, a link to your platform, the categories you handle, and a short description of what you would like to build.
