## 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 sirenic-belgian-insider-trading-transactions-mar-art-19-95466784
```

Example prompt: Pull the FSMA insider dealing summary for Belgian listed company with enterprise number 0428750985 — I want to see whether managers have been net buyers or sellers over the past 12 months.

## When to prefer this

Use this endpoint when you need FSMA-sourced, regulation-compliant (MAR Article 19) insider dealing data for a Belgian listed company and want an aggregated, anonymised view rather than raw per-individual disclosures. It is the right choice for investor due diligence, equity research, or compliance monitoring workflows focused on Belgium. Do not use it for French, Dutch, or other EU markets — use the appropriate country-specific endpoints instead.

## Known failure modes

- 404 emetteur_inconnu — enterprise number is valid but the company is not in the FSMA listed-issuer register
- 404 pays_non_couvert — country code is not BE (only Belgium is supported)
- 400 parametre_invalide — malformed date in the 'depuis' query parameter; payment is cancelled
- No transactions found — company is listed but has filed zero insider notifications in the period
- Non-10-digit enterprise number causes validation failure before payment

## How this service works

Director transactions and insider transactions at Belgian and German listed companies — managers transactions (directors' dealings) under MAR Article 19, as notified to the FSMA and BaFin: are the company's managers buying or selling? Issuer-level aggregate over a rolling 12 months — counts, gross buy and sell amounts, net flow, breakdown by declarer category, and the underlying notifications. BE: 10-digit enterprise number. DE: LEI or ISIN. No individual is ever named.

## Output

A JSON object containing: aggregate counts of buy and sell notifications, gross buy and gross sell amounts in euros, net insider flow (buy minus sell), a breakdown of transaction counts and amounts by declarer category (e.g. board member, senior executive, person closely associated), and a list of the individual underlying FSMA notification records — all anonymised with no individual named.
