A signal no company record carries: what directors do with their own shares. The integration trap is scope — the issuer must belong to the queried authority's register. Take its identifier from that register rather than guessing it, otherwise the call returns a perfectly correct 404.

Catalogue description, exactly as agents read it:
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.
The authority's country code, then the issuer's identifier in that register.
A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

}Price: $0.02. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.
An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

/v1/eu/entreprise/{pays}/{id} — $0.01/v1/eu/agrements — $0.01Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
