Endpoint
GEThttps://api.xynaptic.io/v1/company-relationship?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect potential affiliations, conflicts of interest, or hidden connections between exactly two French companies identified by SIREN. It is more focused than a general company compare endpoint — it specifically surfaces relationship signals (shared people, activity, geography) rather than just financial metrics side by side.
Side effects
- Invalid or non-existent SIREN returns an error or empty result
- Missing one or both SIREN parameters returns a 400 bad request
- Companies with no registry data may return limited relationship signals
- Rate limiting or payment failure (402) if credits are exhausted
