# Market Intelligence API – Euro Area Interest Rates & Yield Curves

> Market Intelligence API – Euro Area Interest Rates & Yield Curves is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Returns euro area government spot yield curves (AAA and all issuers, 3M–30Y maturities), daily changes, 2s10s/3m10y slope metrics, key ECB policy rates, and 10-year sovereign yields with spreads vs the German Bund.

## 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 market-intelligence-api-euro-area-interest-rates-yield-curves-77157e76
```

Example prompt: Give me a snapshot of the euro area interest rate environment right now — the full government yield curve from 3 months to 30 years for both AAA and all issuers, today's ECB rates, and the 10-year spreads of each eurozone country versus Germany.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call snapshot of the euro area rates environment — covering both the full sovereign yield curve by maturity and issuer tier, key ECB policy rates, and country-level spread decomposition. Prefer it over generic macro data APIs when European fixed income context (curve shape, ECB stance, peripheral spreads) is specifically needed, such as for bond pricing, macro strategy, risk assessments, or FX analysis involving the euro.

## Known failure modes

- Data may lag official ECB publication windows if queried very early in the trading day
- No query parameters are accepted — any request body or query string is ignored
- If ECB data source is unavailable, the endpoint may return an error or stale data
- Network timeout if upstream data provider is slow to respond
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Euro bond yields and ECB interest rates: euro area government spot yield curves (AAA and all issuers, 3M to 30Y) with daily changes and 2s10s/3m10y slopes, the key ECB rates, and 10-year yields per country with spreads vs the Bund. Use for the euro rate backdrop.

## Output

A JSON object containing: euro area government spot yield curves for AAA-rated and all-issuer buckets across maturities from 3 months to 30 years; daily basis-point changes for each tenor; 2s10s and 3m10y slope metrics; the three key ECB policy rates (deposit facility, main refinancing, marginal lending); and a per-country table of 10-year sovereign yields with their spread relative to the German Bund.
