NASD API

Introduction

The NASD vendor API gives licensed partners programmatic access to the OTC Securities Exchange: live market data, company and sector reference data, order management, and corporate actions. It is a REST API that returns JSON over HTTPS.

Base URL: https://stagingmobile.nasdng.com/v2
Authentication: Bearer API key, see Authentication
Format: JSON request and response bodies, UTF-8
Versioning: Current version v2, carried in the path

The response envelope

Almost every endpoint wraps its payload in a consistent envelope. Read success to branch, message for a human-readable summary, and data for the result. Paginated list endpoints add a meta or nested pagination object.

One documented exceptionThe market depth order book returns a top-level object rather than the standard envelope. It is called out on that page.

Base currency and time

Amounts are in Naira (₦). Timestamps are ISO 8601 in UTC. Prices are quoted to the exchange's tick precision.

Next steps

Create an API key and authenticate your first request in Authentication, learn the failure model in Errors, then jump into Market data.
