VALR

About VALR

VALR provides a REST API and a companion WebSocket service for interacting with a cryptocurrency exchange. The REST endpoints handle transactional operations such as accessing current and historic market data, submitting trade orders, buying and selling over 60 cryptocurrencies, and withdrawing cryptocurrencies or fiat from VALR wallets. The WebSocket API streams market, order, and balance updates in real time.

Authentication uses API keys with scoped permissions covering view access, trading, transferring funds between primary and subaccounts, withdrawing, and linking bank accounts. Requests must use HTTPS and the application/json content-type, and authenticated calls require a request signature generated via HMAC-SHA512 using the API secret, timestamp, HTTP verb, path, and body. Two-factor authentication must be enabled on an account before API keys can be generated.

The documentation is intended for developers building applications or trading tools against the VALR exchange, including code examples for request signing in Node.js, Go, C#, Python, and Java. An AI Agent Skill is also provided to give AI coding agents context and tools for interacting with the VALR API without prior knowledge of its authentication scheme or endpoints, compatible with agents supporting the Agent Skills specification.
