How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

Output

Returns a JSON object with an array of Treasury yield data points (yield %, maturity label, months, FRED series ID, as-of date) covering all standard maturities, plus meta fields: inversion boolean, 2s10s spread, 3m10y spread, and the as-of date. Includes source attribution to FRED/Federal Reserve Bank of St. Louis.

Example use cases

Example prompt

“What does the US Treasury yield curve look like right now — is it inverted, and what are the 2s10s and 3-month-to-10-year spreads?”

Technical details

Endpoint

GEThttps://2s.io/api/econ/yield-curve?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a complete, current snapshot of the US Treasury yield curve with inversion status and key spread metrics in a single call, sourced authoritatively from FRED. Prefer over scraping Treasury.gov or building your own FRED integration. Ideal for macroeconomic analysis, recession signal detection, and fixed-income context in AI agent workflows.

Side effects

FRED data unavailable or delayed — stale as-of date returned
Network timeout reaching upstream FRED source
Payment not fulfilled via x402 — 402 response with no data
Malformed response if upstream FRED API changes schema
