How this service works
Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.
Output
Returns a list of macroeconomic data sources available through the Fathom API, likely including source names, IDs, and descriptions from the FRED database ecosystem — helping callers identify which sources to query for specific economic indicators.
Example use cases
Exploring available FRED data sources
“What data sources are available through the Fathom macro API? I want to see which institutions or agencies publish economic data I can pull from.”
Finding sources for inflation research
“I'm building an inflation dashboard — can you list all the data sources on Fathom's FRED-powered API so I can identify which ones cover CPI and price index series?”
Scoping economic data for a research project
“Before I start pulling unemployment and interest rate data, can you fetch all the available sources from the Fathom macroeconomic API so I know what's covered?”
Technical details
Endpoint
POSThttps://fredfathom.vercel.app/api/sources?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what macroeconomic data sources are available before querying specific time series. It is the right first step when building economic dashboards, research tools, or automated data pipelines that rely on FRED data. Prefer this over direct FRED API access when you want a pay-per-call model with no API key management, or when operating within an x402 micropayment workflow.
Side effects
- Payment failure (insufficient USDC balance for the $0.04 x402 payment)
- Invalid or malformed POST body causing 400 error
- Service unavailability on the Vercel-hosted endpoint
- Rate limiting or quota exceeded
- Empty or unexpected response if no sources match filter criteria
