# DataNexusAI US-EU Inflation Differential API

> DataNexusAI US-EU Inflation Differential API is a paid API for AI agents from api.datanexusai.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-28).

Returns the current inflation differential between the US and EU, including individual US and EU inflation rates and the computed spread.

## Facts

- Price: $0.01/call

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 datanexusai-us-eu-inflation-differential-api-235a954e
```

Example prompt: What's the current inflation differential between the US and EU — give me both individual rates and the spread between them.

## When to prefer this

Choose this endpoint when you need a quick, ready-computed inflation differential between the US and EU without building your own calculation from raw CPI data sources. It is ideal for agents that need a single numeric spread for dashboards, trade analytics, or economic monitoring workflows. Prefer this over general economic data APIs when you specifically need the US-EU pairing and want micropayment-based pay-per-call access with no subscription overhead.

## Known failure modes

- Payment not provided or USDC micropayment rejected — 402 Payment Required response
- Invalid HTTP method used (only GET/HEAD/DELETE supported) — 405 Method Not Allowed
- Service unavailable or upstream data source outage — 503 response
- Rate limiting or wallet balance exhausted — payment failure or 429 Too Many Requests

## How this service works

Public data API for SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices, and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). Docs and discovery endpoints are free.

Machine-readable discovery: `https://api.datanexusai.org/openapi.json`, `https://api.datanexusai.org/llms.txt`, `https://api.datanexusai.org/.well-known/x402`.

## Output

Returns a JSON object with four fields: an indicator string ('US_EU_INFLATION_DIFFERENTIAL'), the individual US inflation rate, the individual EU inflation rate, and the computed differential (US minus EU) as a numeric value.
