# DataNexusAI EUR/USD Analytics

> DataNexusAI EUR/USD Analytics is a paid API for AI agents from api.datanexusai.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Returns real-time EUR/USD spot rate with derived analytics including 1-month return, annualized volatility, and configurable percentile/z-score statistics over a lookback window.

## Facts

- Endpoint: GET https://api.datanexusai.org/api/v1/fx/eurusd-analytics?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/datanexusai-eur-usd-analytics-383cf6c1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_T9_k5qHFMzmtxVDk8wBg2

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-eur-usd-analytics-383cf6c1
```

Example prompt: What's the current EUR/USD spot rate along with the 1-month return and 21-day annualized volatility? Use a 252-day lookback window for the percentile and z-score stats.

## When to prefer this

Choose this endpoint when you need a combined snapshot of EUR/USD spot price plus derived volatility and return analytics in a single call, especially for trading dashboards, risk monitoring, or macro research workflows. Prefer this over raw price feeds when you need pre-computed annualized volatility and return metrics without doing the math yourself. Best suited for agents that pay per-call via USDC micropayments and need fast, structured FX analytics.

## Known failure modes

- Missing or invalid lookback_days type returns a 400 validation error
- Payment not settled via x402 USDC micropayment returns 402 Payment Required
- Upstream FX data unavailable may return 503 or stale data
- Lookback window longer than available history may return partial or null derived stats

## 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 the current EUR/USD spot rate, a derived analytics object containing the 1-month return percentage and 21-day annualized volatility percentage, and an endpoint identifier string. Lookback window used for percentile/z-score calculations is configurable via the lookback_days parameter.
