# DataNexusAI Market Anomalies API

> DataNexusAI Market Anomalies API is a paid API for AI agents from api.datanexusai.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-03).

Detects statistical anomalies in EU agri-food commodity prices across countries using Z-score thresholds and percentage change filters

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-market-anomalies-api-46c8117d
```

Example prompt: Show me the top 10 EU agri-food price anomalies for wheat (commodity 1001) in Bulgaria and Romania, using a Z-score threshold of 2.5 and a minimum 40% price deviation.

## When to prefer this

Use this endpoint when you need statistically-driven anomaly detection on EU agri-food commodity pricing — particularly when you want to filter by specific country codes, commodity identifiers, Z-score sensitivity, or minimum percentage deviations. Prefer this over raw price lookup endpoints when the goal is market surveillance, early-warning detection, or identifying outliers rather than retrieving baseline prices.

## Known failure modes

- Missing or invalid required query parameters may return 400 Bad Request
- Payment not received or USDC micropayment failure returns 402 Payment Required
- Unsupported country codes or commodity codes may return empty results or 422
- Rate limiting or quota exceeded may return 429 Too Many Requests
- No anomalies found for given filter combination returns empty result set

## 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`.

Human docs: `/docs` and `/api/`.

## Output

A list of detected price anomalies in EU agri-food commodity markets, each record likely including the commodity code, country, statistical deviation metrics (Z-score), percentage price change, and contextual pricing data that flagged the anomaly.
