Combine country indicators, FX and calendars in one application with Narwhal. REST and hosted MCP share its monthly request allowance. EIA provides free energy statistics covering electricity, petroleum, natural gas and other energy sectors, with API access and bulk downloads.
Choose Narwhal for country economics, FX and calendar features in your app, with one account for HTTP requests and hosted agent tools.
EIA energy statistics and Narwhal country economics serve separate data jobs.

-H "Authorization: Bearer YOUR_API_KEY"Narwhal Free includes 3,000 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.
EIA is the better pick for detailed energy statistics, outlooks and bulk energy files. Its API is free with a registered key and provides the direct route to those energy datasets. Narwhal has no equivalent live energy-statistics endpoint: the CPI example supports a separate economic workflow, rather than replacing EIA's series. An application researching energy and broader economics can use both sources for their respective jobs.
Yes. Narwhal Free includes 3,000 successful requests per month, commercial app use and both REST and hosted MCP access. This covers country indicators, FX and calendars; EIA energy datasets remain a separate source.
API v2 allows up to 5,000 JSON rows per response, with a smaller XML limit. Page through larger results or use bulk downloads. EIA applies throttling and can suspend a key temporarily when usage is excessive.
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.
