Getting Started with the Vaultera API: A Developer's Guide

Why build on Vaultera?

The Vaultera API gives developers programmatic access to the same transparent banking infrastructure that powers our consumer platform. Whether you are building a payroll system that needs verifiable payment records, a marketplace that requires escrow with real-time proof of funds, or a financial dashboard that surfaces on-chain verification data, our API provides the primitives you need.

Every API response includes a verification hash that can be independently checked against the public ledger. This means your application inherits Vaultera's transparency guarantees without any additional implementation work. Your users can verify transactions directly, and your compliance team can audit the complete trail programmatically.

Authentication and setup

Vaultera uses OAuth 2.0 with scoped API keys for authentication. To get started, create an API application in your Vaultera dashboard and generate a key pair. All API requests must be made over HTTPS, and we enforce mutual TLS for production environments.

curl -X POST https://api.vaultera.com/v1/auth/token \
  -H "Content-Type: application/json" \
  -d '{
    "client_id": "your_client_id",
    "client_secret": "your_client_secret",
    "grant_type": "client_credentials",
    "scope": "accounts:read transfers:write"
  }'

Core endpoints

The API is organized around five core resource types. Each endpoint returns JSON responses with consistent pagination, error formatting, and verification metadata.

• Accounts: Create, read, and manage deposit accounts. Each account includes a real-time balance and a verification hash that can be checked against the on-chain Merkle tree.
• Transfers: Initiate ACH, wire, and internal transfers. Every transfer generates a verification ID upon settlement.
• Transactions: Query the complete transaction history for any account, with filtering by date, amount, type, and verification status.
• Verification: Look up on-chain proofs for any transaction or account balance. Returns the Merkle path, block hash, and a direct link to the public ledger.
• Webhooks: Subscribe to real-time events for account changes, transfer completions, and verification confirmations.

Rate limits and best practices

The Vaultera API enforces rate limits of 1,000 requests per minute for standard keys and 10,000 requests per minute for enterprise keys. We recommend using webhooks for real-time updates rather than polling, caching verification proofs locally since they are immutable once confirmed, and batching related operations using our bulk endpoints when processing more than 50 items.

The best integrations we have seen treat verification as a first-class feature, not an afterthought. Surface the verification hash in your UI. Let your users click through to the proof. Transparency compounds -- the more visible it is, the more trust it builds.

Getting help

Our developer documentation lives at docs.vaultera.com and includes interactive API explorers, code samples in Python, JavaScript, Go, and Ruby, and a sandbox environment with test data. If you get stuck, our developer relations team monitors the Vaultera Discord and responds to GitHub issues within 24 hours. We are building this API for developers, and your feedback directly shapes our roadmap.
