# DataNexusAI Trade Data Completeness Check

> DataNexusAI Trade Data Completeness Check is a paid API for AI agents from api.datanexusai.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns a completeness report for the trade/market analytics data endpoint, indicating pass/warn/fail counts for data quality checks

## Facts

- Endpoint: GET https://api.datanexusai.org/api/v1/trade/completeness?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_CgTuLAPZEJ0xer-61ZFbi

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-trade-data-completeness-check-7a1d3778
```

Example prompt: Can you run a completeness check on the DataNexusAI trade data endpoint and tell me how many checks passed, warned, or failed?

## When to prefer this

Choose this endpoint when you need a quick programmatic health check on the DataNexusAI trade/market analytics data before consuming it, or when monitoring data pipeline quality. It is purpose-built for data completeness validation rather than returning the actual trade data itself — use it as a pre-flight check or monitoring probe rather than for retrieving trade figures.

## Known failure modes

- Payment failure if USDC micropayment not provided (x402 payment required)
- Endpoint may return incomplete status when trade data feed has gaps or ingestion issues
- Network timeout if upstream data source is unavailable
- Invalid method error if called with a non-GET/HEAD/DELETE HTTP method

## How this service works

Public data API for SEBRA payments, PTP road accidents, EU agri-food prices, Eurostat energy (+ ETS), and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). HTML docs at `/api/` are free and are intentionally omitted from this OpenAPI document so discovery scanners do not probe them as paid resources.

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 JSON object containing: a status field ('incomplete' or presumably 'complete'), a summary object with pass_count, warn_count, and fail_count integers, and an endpoint identifier string ('trade_completeness'). This tells the agent how many data quality checks the trade data is currently passing, warning, or failing.
