Bring your own key. This API needs your own nFusion Solutions Market Data API key - get one from the provider, add it once below, and the proxy injects it on every call. Your OmniStream plan covers the unified SDK, key storage, and proxy - the provider's own rate limits still apply to your key.

This is a community listing. If you own this API, you can request ownership.

Install the SDK

npm install omnistream-sdk

import { OmniClient } from "omnistream-sdk";

const omni = new OmniClient({ token: process.env.OMNI_KEY! });

// One key reaches every API on the marketplace.
const data = await omni.call("nfusionsolutions/Currencies_History_GET");

One install, one key - the same client calls every API on the marketplace.

Frequently asked questions

Do I need an API key to use nFusion Solutions Market Data API?

Yes. nFusion Solutions Market Data API uses apiKey authentication, so you bring your own key from the provider. You store it once on OmniStream and the proxy injects it into every call, so your code only ever sends your Omni key.

What can you do with the nFusion Solutions Market Data API API?

nFusion Solutions provides REST APIs that deliver enterprise-grade financial data. It exposes 17 endpoints over GET, including GET /api/v1/Currencies/history, GET /api/v1/Currencies/history/supported, GET /api/v1/Currencies/rate.

How do I call nFusion Solutions Market Data API from Python, TypeScript, Rust or Go?

Install the OmniStream SDK for your language and call nFusion Solutions Market Data API through it. The client is generated from this API's OpenAPI spec, so parameters and responses are fully typed, and the same client also calls every other API in the marketplace.

Is nFusion Solutions Market Data API free to use on OmniStream?

You can start on the free plan. OmniStream charges for the unified SDK, key storage and proxy rather than for nFusion Solutions Market Data API itself, and nFusion Solutions Market Data API's own rate limits still apply to your provider key.
