Commercial-register publications of a Swiss company

The Swiss Official Gazette of Commerce publishes each company's life. This route reads its public API live and serves the structured part of each publication — the company before and after, closed-list change flags — without the free text, which names persons.

What the route returns

Catalogue description, exactly as agents read it:

Swiss commercial-register publications from the Official Gazette of Commerce (SOGC/SHAB, SECO public API, live, since July 2018): every registration, change and deletion carrying the UID — date, number, canton, office, the company as published (name, UID, seat, legal form, purpose, capital, address without c/o) and closed-list change flags (name, seat, address, purpose, capital, form, bankruptcy, liquidation…); free text withheld (persons). Query: /v1/eu/entreprise/CH/CHE-102.732.681/evenements.

Expected identifier

UID in the form CHE-xxx.xxx.xxx (dots and hyphen optional).

A wrongly formatted identifier in the path 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. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

Price and billing

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.

What this route does not do

texte_retenu: true on every publication: persons are never served; online archive since 1 July 2018, an absence goes no further back.

How you pay

Every 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.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

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.
