# Genexxis Yields - Yield Curve Spreads & Inversions

> Genexxis Yields - Yield Curve Spreads & Inversions is a paid API for AI agents from yields.genexxis.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-29).

Returns US, euro area, and Morocco yield curve slope metrics (2s10s and 3m10y in basis points with inversion flags) plus cross-market 10Y spreads between those regions.

## Facts

- Endpoint: GET https://yields.genexxis.com/spreads?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability genexxis-yields-yield-curve-spreads-inversions-76846cf0
```

Example prompt: Pull the latest yield curve slope data — give me the 2s10s and 3m10y spreads in basis points for the US, euro area, and Morocco, including whether any curve is inverted, and the cross-market 10Y spreads between them.

## When to prefer this

Choose this endpoint when you need pre-computed yield curve slope metrics and cross-market spread comparisons across US, euro area, and Morocco in a single call, rather than fetching raw yield curves and computing slopes yourself. It is ideal for macro monitoring dashboards, recession-signal detection, or sovereign bond spread analysis where inversion flags are needed out of the box.

## Known failure modes

- Stale or unavailable market data may result in outdated as-of dates
- No input filtering currently exposed, so all three markets are always returned
- If underlying bond market data is unavailable, the API may return an error or empty response
- Network or payment (x402) failures at $0.003 USDC per call

## How this service works

Official government yield curves for agents: U.S. Treasury par yield curve (1M-30Y, U.S. Treasury), euro area AAA spot curve (3M-30Y, ECB) and Morocco Treasury bond reference rates (Bank Al-Maghrib secondary market), each with changes vs 1 month and 1 year ago; curve slopes (2s10s, 3m10y) with inversion flags, cross-market 10Y spreads, and interpolated yields at any tenor. Refreshed every 6 hours from official publications.

## Output

A JSON object with two arrays: 'curves' containing per-country records with as-of date, 2s10s slope in bp, 3m10y slope in bp, and boolean inversion flags; and 'cross' containing cross-market 10Y spread pairs (US-EA, MA-US, MA-EA) in basis points.
