Endpoint

POSThttps://builtwith.x402.paywithlocus.com/builtwith/company-to-url

When to prefer

Use this endpoint when you have a company name and need to resolve it to one or more website URLs or domains, especially for lead enrichment, competitive research, or building a web presence profile. Prefer this over manual search when you need programmatic, structured results from a database of 100M+ websites. This is the right choice when you know the company name but not its exact web properties.

Side effects

Company name not found in BuiltWith database — returns empty data object
Ambiguous company name matches multiple unrelated companies — results may include irrelevant domains
Payment failure or insufficient USDC balance — request rejected before execution
AMOUNT parameter missing or invalid — may default to a system limit or return an error
Rate limiting or upstream BuiltWith API unavailability — request times out or returns error
