# DataNexusAI Agri-Food Data Completeness Check

> DataNexusAI Agri-Food 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 2026-10-23).

Returns a completeness status report for the EU agri-food prices dataset, summarizing how many data checks passed, warned, or failed.

## Facts

- Endpoint: GET https://api.datanexusai.org/api/v1/agrifood/completeness?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_1zkQHzGpaNgTUAAx8Pv0p

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-agri-food-data-completeness-check-0efd42df
```

Example prompt: Can you check the current completeness status of the EU agri-food prices dataset on DataNexusAI — I want to know how many checks passed, warned, or failed?

## When to prefer this

Choose this endpoint when you need a quick, structured data quality summary for the EU agri-food prices dataset specifically — particularly before ingesting or analyzing that data, or when setting up automated monitoring of pipeline health. Prefer it over manually inspecting raw data records when you want a single pass/warn/fail summary. Not suitable for retrieving actual agri-food price values.

## Known failure modes

- Payment not provided or rejected — endpoint returns 402 Payment Required if valid USDC micropayment header is missing
- Dataset temporarily unavailable — may return 503 or error status if upstream EU agri-food data source is down
- Malformed request — passing unsupported HTTP methods returns 405
- Network timeout if the completeness check takes too long to complete upstream

## 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 with a 'status' field (e.g. 'partial', 'ok', 'fail'), an 'endpoint' field identifying this as the agrifood_completeness check, and a 'summary' object containing integer counts for pass_count, warn_count, and fail_count across all data quality checks run against the EU agri-food prices dataset.
