Ocean.io Bulk Company Lookup & Enrichment

Use this endpoint when you have a batch of company domains (up to 1000) and need to enrich them all in one API call rather than making individual lookups. Ideal for CRM enrichment workflows, prospect list qualification, or any scenario where you already have domain names and need structured firmographic data at scale. Prefer the single Company Match endpoint for one-off lookups or when you only have a company name rather than a domain.

• Domain not found in Ocean.io database — company returned as unmatched or null
• Exceeding 1000 domain limit per request — request rejected with validation error
• Invalid domain format — malformed URLs or non-domain strings cause per-record errors
• Insufficient credits — request fails if account balance is depleted
• Rate limiting — too many requests in a short window returns 429 error
• Partial matches — some domains in a batch may enrich successfully while others do not
