## 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 sebra-taxonomy-by-year-ea3bd77d
```

Example prompt: Can you pull the SEBRA government spending category taxonomy for 2019 in EUR so I can see how Bulgaria classified its public payments that year?

## When to prefer this

Use this endpoint when you need structured, machine-readable taxonomy of Bulgarian government spending categories from the SEBRA system for a specific year, especially when building fiscal analytics, transparency dashboards, or year-over-year budget comparisons. Prefer this over general web search when you need authoritative totals per category in BGN or EUR with consistent category keys.

## Known failure modes

- Missing required 'year' parameter returns a 400 or validation error
- Invalid year value (non-integer or out-of-range) may return empty results or an error
- Unsupported currency value (not BGN or EUR) may return an error or default
- Payment failure via x402 (insufficient USDC balance) blocks access to paid endpoint
- Year with no data available returns empty items array
- Network timeout on slow upstream data retrieval

## 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 JSON object containing the requested year, a list of spending category items (each with a Bulgarian-language category name, a machine-readable category_key such as 'salaries', and a total_amount string), and the endpoint name. Currency is BGN or EUR depending on the query parameter.
