Overview

Welcome! This reference brings together all NUVA Labs' APIs in one place. Each section provides endpoint routes, required parameters, response models, and example payloads.

What's Inside​

In this reference, we have grouped operations by product. Within each product you'll find feature sections with related operations.

  • ProvConnect (Identity & Access): Accounts, attributes/attestations, authorization and fee‑grants, sanctions, address search and balance details (Plus), and protocol REST queries.

  • AssetManager (Tokenization): Markers (fungible) and scopes (non‑fungible): lifecycle operations, access control, supply and holders, denom metadata, value ownership, records, and NAV.

  • BlockVault (Vault & Proof): Vault write builders for custody-aware flows, confidential data proofing (hash/anchor), off-chain storage locators, sessions, batch ingestion, contract execution jobs (CEE).

  • Trade & Transfer (Settlement): Markets, orders, commitments, payments, and fee estimates to power post‑trade and settlement workflows.

  • Blockchain Integration & Data: Node RPC (JSON‑RPC + WebSockets), protocol REST queries, ABCI, blocks/tx search, event subscriptions, and chain configuration/governance reads.
