How this service works
Pull a key market-signal macro series from the Federal Reserve (FRED) by slug: vix, yield-curve-10y-2y, yield-curve-10y-3m, high-yield-spread, ig-spread, breakeven-10y, real-yield-10y, jobless-claims, consumer-sentiment, mortgage-30y, financial-conditions, recession-probability. Each returns the latest value, prior, change, year-over-year, and recent history. No ticker needed. From x402stock
Output
A JSON object with the FRED source label, as-of date, series ID, full title, unit, and frequency, plus the latest {date, value} pair, the prior {date, value} pair, the absolute change, change percent, year-over-year percent change, and an array of recent historical {date, value} data points.
Example use cases
Yield curve inversion monitoring
“Pull the 10-year minus 2-year yield curve spread from FRED and tell me the latest value, what it was before, and whether it's more or less inverted than a year ago.”
Recession risk dashboard update
“Get me the current recession probability from FRED, including recent history, so I can update my macro risk dashboard.”
Credit market stress check
“What's the latest high-yield credit spread from FRED? Show me the current reading, the prior, and the year-over-year change so I can gauge credit market stress.”

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/fred/{series}When to prefer
Use this endpoint when you need quick, no-configuration access to one of 12 pre-curated FRED macro market-signal series (VIX, yield curves, credit spreads, breakeven inflation, real yields, jobless claims, consumer sentiment, mortgage rates, financial conditions, recession probability) without needing a FRED API key or knowing the underlying series ID. It is especially valuable for agents building macro dashboards, risk monitors, or economic summaries where you want latest + prior + YoY context in a single call. Prefer alternatives if you need arbitrary FRED series beyond the 12 supported slugs or require raw FRED API access.
Side effects
- Invalid or unsupported series slug returns an error — only the 12 documented slugs are accepted
- Payment failure via x402 results in a 402 response with no data
- Stale or missing FRED data may return nulls for latest, prior, change, or yoy_percent fields
- Network or upstream FRED API outage may cause 5xx errors
