## When to prefer this

Use this endpoint when you need quick lookup of the top-funded Bulgarian government budget programme(s) from the SEBRA public payments system for a specific calendar year. It is ideal for fiscal transparency research, public finance analysis, or building dashboards over Bulgarian state expenditure data. Prefer this over generic web search when you need structured, machine-readable data with currency denomination options.

## Known failure modes

- Year not found or no data available for that year — returns empty result or 404
- Invalid currency code provided — validation error
- Payment required (402) if USDC micropayment not completed via x402 protocol
- Year parameter missing or non-integer — schema validation error
- Limit parameter out of expected range — may return error or be clamped

## 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
