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.
Example use cases
Pre-investment insider sentiment check
“Before I take a position in this Belgian stock, can you check whether the company's managers have been net buyers or sellers lately? The enterprise number is 0428750985 — I want the aggregate buy/sell flow for the last 12 months from FSMA filings.”
Equity research insider activity report
“I'm writing a report on UCB SA (Belgian enterprise number 0428750985). Can you get me a breakdown of all MAR Article 19 insider transaction notifications filed with the FSMA over the past year — total counts, gross buy/sell amounts, and which category of insiders is most active?”
Compliance monitoring for a listed issuer
“Our compliance team needs to review insider dealing disclosures for our Belgian listed entity, enterprise number 0428750985, from 2024-01-01 onward — can you pull the FSMA MAR insider transactions summary including the underlying notifications?”
Technical details
Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/:pays/:id/transactions-dirigeantsWhen to prefer
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.
Side effects
- 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
