-H "Authorization: Bearer YOUR_API_KEY"Narwhal Free includes 5,000 successful requests each month and permits commercial apps. Use that allowance for a dashboard, scheduled data fetches or an agent integration. Move to Basic for 100,000 monthly requests as usage grows, with the same account and authentication.
REST and hosted MCP reach the same data through one account. Your application can fetch JSON while an agent uses the hosted tools, with every successful call counted once against the shared allowance. One quota makes the combined workload straightforward to budget.
Narwhal's economics catalogue spans 36 countries, with a coverage table for each indicator. Country and indicator paths organize requests around the data your application uses. Combine observations with FX, public holidays and release dates to build country dashboards through the same account.
Tiingo covers stocks, ETFs, mutual funds, forex, crypto and news. Power provides 10,000 requests an hour and 100,000 a day for $30 a month. Internal commercial use costs $50 a month. Redistribution is priced through sales.
Yes. Narwhal Free includes 5,000 successful requests per month, commercial app use and both REST and hosted MCP access. FX values are the previous day's close. Free history covers the last 12 months, subject to available records.
Tiingo Starter is limited to internal use. Internal commercial access costs $50 a month, while redistribution is priced through sales. Narwhal Free permits commercial apps; resale needs Enterprise.
Replace the request URL and authentication, then map the JSON response into your application's fields. The examples use standard fetch in JavaScript and requests in Python, so integration fits an ordinary HTTP client. Keep your key on the server and carry the response's units, dates and missing values into your display or calculations.
The shared cap applies to successful REST and MCP requests together. There are no automatic overage charges. Basic includes 100,000 monthly requests; quotas reset each month even when you pay yearly.
