How this service works
Xynaptic Company Changes — what recently changed in a French company: officers, status, HQ, activity, accounts — detected against the last snapshot (shared with company-monitor). Parameter: ?siren=.
Output
A structured diff showing what has changed since the last snapshot for the specified French company, potentially including new or removed officers, changes in legal status, headquarters address updates, NAF/activity code changes, and shifts in annual account data.
Example use cases
Due diligence before signing a contract
“Before we finalize this supplier agreement, can you pull the latest changes for the French company with SIREN 342317157 — I need to know if their legal status, directors, or registered address have changed recently.”
Monitoring a competitor for strategic shifts
“Keep an eye on SIREN 410769175 for me — has anything changed at that company lately, like new officers, a different activity code, or a new headquarters?”
Compliance check on a portfolio company
“Can you tell me what has changed recently for the company with SIREN 800508100? I need to flag any officer replacements or status changes for our compliance records.”

Endpoint
GEThttps://api.xynaptic.io/v1/company-changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect recent changes to a French company's official registered data — especially for due diligence, compliance monitoring, or competitive intelligence workflows. It is specifically designed as a change-detection diff against a snapshot, making it more efficient than fetching full company profiles when you only care about what is new or different. Prefer it over static company lookup endpoints when the goal is monitoring or alerting on mutations.
Side effects
- Invalid or non-existent SIREN returns an error or empty result
- No changes detected since last snapshot returns an empty diff
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Malformed SIREN parameter (not 9 digits) may return a validation error
- Company not covered in the registry snapshot may yield no data
