When should you use this API?

Use cases and limitations are published with the API so humans and agents can integrate it correctly.

Use when

  • You have a French SIREN or SIRET and need to confirm that the company or establishment exists in the public source.
  • You need its current administrative active/closed status before another automated step.

Avoid when

  • You only have a company name and need to discover its identifier; use company/fr/search.
  • You need directors, financials, legal risk or compliance checks; use the corresponding specialized endpoint.

Limitations

  • This verifies public administrative existence and status only; it is not KYC, identity assurance or beneficial-owner verification.
  • Returned fields depend on what the public company source exposes for the identifier.
