Financial Data API

One API, Five Real-Time Financial Data Categories

FinanceFlowAPI’s Financial Data API gives you a single key and one consistent JSON format to query economic calendar events, commodity prices, government bond yields, currency exchange rates and macroeconomic indicators, all real-time and historical, without integrating a separate data vendor for each asset class.

Financial Data API Catalog

FinanceFlowAPI’s Financial Data API is organized into topical categories, each with its own dedicated endpoint page covering parameters, response schema, errors and code examples. This page indexes every category currently documented. Start here to find the right one, then follow through for the full reference. For plans, billing and account setup, see the FinanceFlowAPI homepage.

Global API Capabilities

  • One key, one format: every endpoint below shares the same api_key authentication and the same JSON response envelope (success, code, message, meta, data).
  • Real-time and historical: several categories return live data plus a date-range history. Exact historical support varies by category, see each endpoint page for specifics.
  • Consistent error handling: the same HTTP status codes mean the same thing across every endpoint (see below).
  • Per-tariff rate limits: request volume and your per-minute rate limit scale with your subscription plan.

Endpoint Catalog

Five data categories, each with a dedicated endpoint page. Pick one to see live examples, parameters and errors. More categories are being added.

API Authentication

Every endpoint above uses the same authentication: pass your key as an api_key query parameter on any request. One key works across every data category. There is no separate key per endpoint. See the full API documentation for the exact parameters of each endpoint.

Common Response Format & Errors

Every endpoint returns the same JSON envelope:

{
  "success": true,
  "code": 200,
  "message": "OK",
  "meta": {
    "timestamp": 1787485535,
    "request_id": "6a8add5f5274d"
  },
  "data": [...]
}
HTTP codeMeaning
200OK: request succeeded
400Bad request: missing or invalid parameters
403Invalid or missing API key, expired subscription, request limit reached, or the endpoint isn’t included in your plan
404No data found for the request, or unknown endpoint
429Rate limit exceeded for your subscription plan
500Internal server error (rare)

Exact error conditions vary slightly by endpoint. See each endpoint page’s own Errors table for specifics.

Quick Start

  1. Get an API key. Create a FinanceFlowAPI account and choose a plan. See Pricing & Access below for current plans and limits.
  2. Make your first request. Every request follows the same shape: GET https://financeflowapi.com/api/v1/{endpoint}?api_key=YOUR_API_KEY&.... Pick a category above for its exact endpoint name and parameters.
  3. Go deeper. See the full API documentation for every parameter, response field and error code.

Why FinanceFlowAPI

Most financial data needs mean juggling several vendors: one for market events, another for commodities, a third for FX, a fourth for bonds. FinanceFlowAPI replaces that with a single integration:

  • One key, one format, five categories: the same api_key and the same JSON response envelope work across economic calendar, commodities, government bonds, currency rates and economic indicators, so you build one integration instead of five.
  • Consistent error handling: the same HTTP status codes (400/403/404/429/500) mean the same thing across every endpoint, instead of a different error contract per data vendor.
  • Real-time and historical together: several categories expose both current values and date-range history through the same endpoint family, without a separate historical-data product.
  • Broad, verified coverage: 83 countries for economic events, 102 commodities, 54 countries for government bonds, 628 currency pairs and 660+ economic indicators across 131 countries. See the Endpoint Catalog above for details.

FAQ

Is there a free trial or free plan?

No. FinanceFlowAPI is a paid API from the first request. See Pricing & Access above for current plans, limits and pricing.

Do I need a separate API key for each data category?

No. One api_key authenticates every endpoint across all five categories, subject to which endpoints your plan includes.

What’s the difference between this page and the category pages?

This page indexes all five categories and documents what’s common to every endpoint: authentication, response format and errors. Each category has its own page with the exact parameters, response schema and code examples for that category’s endpoints.

Is data available for both real-time and historical use cases?

It varies by category: some endpoints return live values only, others also support a date-range history. Check each category’s own page for what it supports.
