How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
Returns a JSON object with the FRED series title, unit, frequency, source, latest date/value, prior date/value, absolute change, percent change, year-over-year percent change, an as-of timestamp, and a history array of recent data points.
Example use cases
Check latest CPI inflation reading
“Pull the latest CPI inflation data from FRED — give me the current reading, how it changed from the prior period, and the year-over-year percent change so I can see where inflation stands right now.”
Fetch current unemployment rate
“What's the most recent unemployment rate from FRED? Grab the UNRATE series and show me the latest figure, the change from last month, and how it compares to a year ago.”
Look up Fed funds rate today
“I need the current federal funds rate — pull it from FRED and tell me the latest value, what it was before the last change, and the year-over-year difference.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/fred/%7Bseries%7DWhen to prefer
Use this endpoint when you need structured, pre-processed economic indicator data from FRED with computed change metrics (absolute, percent, YoY) in a single call — ideal for AI agents that need clean JSON without parsing raw FRED XML/JSON themselves. Prefer over direct FRED API access when you want pay-per-call pricing with no API key management, and when you need VIX, CPI, unemployment, GDP, Fed funds rate, or similar macro series with delta computations already done.
Side effects
- Invalid or unknown series ID returns an error or empty response
- Series exists but has no recent data (discontinued series)
- Payment failure via x402/USDC prevents request from completing
- Rate or network timeout for slow FRED data fetches
- Malformed series ID path parameter causes 400-style error
