# ADDX Open API

**Canonical:** https://apis.io/apis/addx/addx-open-api/  
**Provider:** ADDX — https://apis.io/providers/addx/  
**Documentation:** https://api-docs.addx.co/open-api/

ADDX Open API is published by [ADDX](https://apis.io/providers/addx/) on the [APIs.io](https://apis.io/) network. Tagged areas include Digital Securities Exchange, Private Markets, Wealth Management, Digital Assets, and Capital Markets. The published artifact set on APIs.io includes an API reference, authentication docs, and rate-limit docs.

Publicly documented REST API that connects an external system to the ADDX platform. Roughly 68 operations across five documented groups — Account Management (account, balance, EAM investor, portfolio, transaction and wallet detail, plus STO subscription, subsequent-subscription and redemption flows for both self and EAM-managed investors), Market Data (aggregated order book, market depth, market state, token list, ticker feed, trade feed, account balances on the trading engine), Reporting (report types, report listing, downloads), Fiat Flow (bank-account management, document upload, fiat deposit and withdrawal with OTP confirmation, wealth-manager distribute/collect) and Digital Assets (balances, deposit addresses, withdrawal fees, email and mobile OTP, identity verification, withdrawal confirmation). Requests are signed with an HMAC-SHA256 X-Signature over the timestamp and HTTP method using a Key ID and secret passphrase the user generates in the platform's API Settings. The base URL is deliberately not published — ADDX issues it per environment and per use case on request — so the documented paths are relative to a host only a provisioned partner holds.
