Build on Nexaria's asset framework
A preview REST API and a pluggable adapter framework designed to reach across the xSPECTAR, XRPL, and EVM ecosystems from a single integration surface.
Partner API preview. The public REST API is not yet live — the endpoints below describe the planned surface so partners can design ahead. Adapters marked Live are already operating inside the platform today (XRPL wallet reads, NFT minting, and on-chain checkout); the rest are integration-ready and switch on as providers are onboarded.
Design
One adapter framework, many worlds
Each ecosystem is reached through a dedicated adapter with a shared interface. Add a world without rewriting your integration — the framework normalizes assets, listings, and events into one shape.
Adapters
Ecosystem adapter framework
Adapters flip to Live automatically the moment their provider is connected — the rest ship integration-ready behind the same shared interface.

REST API
Preview endpoints
A REST-style surface for assets, listings, and webhooks. Shapes may change before general availability.
| Method | Endpoint | Description |
|---|---|---|
| GET | /api/v1/assets | List and filter digital assets across connected adapters. |
| GET | /api/v1/listings | Retrieve active marketplace listings (sell / rent / lease). |
| POST | /api/v1/webhooks | Register a signed webhook for listing and payment events. |
Signed webhooks
Every webhook payload will carry a signature you verify against a shared secret — the same pattern we use for Stripe events — so you can trust the source.
API keys
Keys will be issued to Enterprise and White-Label plans, scoped by role, with rotation and revocation from your dashboard.
