## 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-unusual-payments-detection-d8dfdb11
```

Example prompt: Pull the top 10 unusual payments from Bulgaria's SEBRA system for calendar year 2022, in BGN.

## When to prefer this

Use this endpoint when you need to programmatically surface statistically unusual or anomalous payment records from Bulgaria's official SEBRA government payment system. It is the right choice for fiscal transparency research, investigative journalism, anti-corruption monitoring, or budget analytics focused specifically on Bulgarian public sector payments. Prefer it over generic financial APIs when the domain is Bulgarian government spending and you need date-range or year-based anomaly filtering with BGN/EUR denomination.

## Known failure modes

- Missing required 'from'/'to' or 'year' parameter returns a 400 bad request
- Invalid currency value (not BGN or EUR) may return a validation error
- Date range too broad or no anomalies found returns an empty result set
- Payment required (402) if USDC micropayment via x402 is not included
- Rate limiting or quota exhaustion returns a 429 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.

## Output

A list of unusual or anomalous payment records from the Bulgarian SEBRA government payment registry, filtered by the specified date window or year. Each record typically includes payment amounts, identifiers, and metadata that flag it as statistically irregular. Results are returned up to the configured limit and denominated in the requested currency (BGN or EUR).
