How this service works
Pay-per-call data for AI agents: skill-ranked Polymarket traders, FDA drug and hospital data, oil markets, Wikipedia attention, travel delay risk and SEC filings, plus a daily Morning Brief. Paid in USDC on Base with x402, no API key or account.
Output
Returns a structured dataset including: current daily yields for all standard Treasury maturities (1M, 3M, 6M, 1Y, 2Y, 3Y, 5Y, 7Y, 10Y, 20Y, 30Y), the 10Y-2Y and 10Y-3M spreads, boolean inversion flags for each spread, and yield changes versus the prior day, one month ago, and one year ago.
Example use cases
Recession signal monitoring for macro dashboard
“Check the yield curve right now and tell me if it's inverted — specifically the 10Y-2Y and 10Y-3M spreads — and how that compares to where we were a month and a year ago.”
Daily fixed income briefing for portfolio manager
“Give me today's full Treasury yield curve snapshot, from the 1-month bill out to the 30-year bond, including how each yield has moved since yesterday.”
Interest rate trend analysis for economic research
“What does the current U.S. yield curve look like and how have rates shifted over the past year? I need the spreads and inversion flags too.”
Technical details
Endpoint
GEThttps://www.x402pulse.dev/v1/wallstreet/yield-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, ready-to-use snapshot of the entire U.S. Treasury yield curve with recession-signal flags and multi-horizon change data already computed. It eliminates the need to hit multiple Federal Reserve or Treasury data feeds and manually calculate spreads or inversions. Ideal for macro dashboards, economic monitoring agents, or any workflow where yield curve inversion is a key signal.
Side effects
- Treasury market closed (weekends/holidays) may result in stale or unavailable data
- Upstream data source delay may cause temporary unavailability
- Payment failure (insufficient USDC balance) results in 402 response
- Rate limiting if fair-use thresholds exceeded without Pro subscription
