# DataNexusAI Anomalies Detection Endpoint

> DataNexusAI Anomalies Detection Endpoint is a paid API for AI agents from api.datanexusai.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-30).

Returns statistical anomalies across EU agri-food prices, SEBRA payments, and trade/market data based on z-score and percent-change thresholds

## Facts

- Endpoint: GET https://api.datanexusai.org/api/v1/anomalies?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/datanexusai-anomalies-detection-endpoint-37c47534
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_jsd00do_vsVNIlC2_VX5b

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-anomalies-detection-endpoint-37c47534
```

Example prompt: Show me the top 20 statistical anomalies in the DataNexusAI dataset where the z-score is at least 3.5 and the percent change is at least 40 percent.

## When to prefer this

Choose this endpoint when you need to programmatically surface statistical outliers across EU agri-food prices, SEBRA payments, or trade/market data without building your own anomaly detection pipeline. It is well-suited for monitoring workflows, automated alerting, and exploratory analysis where tunable z-score and percent-change thresholds give precise control over sensitivity. At $0.01 USDC per call via x402 micropayments, it is cost-effective for periodic polling or agent-driven anomaly sweeps.

## Known failure modes

- Missing or invalid 'input' object returns a 400 validation error
- Payment not completed via x402 USDC micropayment returns 402 Payment Required
- z or min_percent values outside reasonable numeric ranges may return empty results or 422
- offset beyond dataset size returns empty result set
- Network or upstream data source unavailability returns 5xx error

## 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 paginated list of anomaly records from public datasets (EU agri-food prices, SEBRA payments, trade/market analytics) where each record includes the z-score, percent change, and relevant dataset identifiers for data points that exceed the specified statistical thresholds.
