Saylor Innovations Data Desk — French Company Register Lookup

Choose this endpoint when you need authoritative, official French company data sourced directly from the INSEE Sirene register — especially for KYC, supplier verification, due diligence, or enriching CRM records with legal form, NAF codes, and official addresses. Prefer this over general web search when you need structured, registry-grade data rather than scraped or crowd-sourced business information.

• No matching companies found for the query — returns empty companies array
• Invalid SIREN/SIRET format — may return no results or an error
• Query too ambiguous (very common name) — returns up to the limit with no guarantee of the right company
• Sirene data may lag real-world changes — recently dissolved or created companies may not appear
• Rate limiting or payment failure — HTTP 402 if payment not provided
• limit parameter out of range (must be 1–10) — may default or error
