/**
 * Verify a business entity by name in a specific jurisdiction. Returns verification results synchronously if available within timeout, or a job ID for async retrieval via GET /v1/verify/status/:jobId. Charges credits based on tier: quick (1 credit), deep (15 credits), deep + force_refresh (25 credits). The response includes `full_verification_available` indicating whether deep verification is supported for the jurisdiction. When deep is not available, a `reason` object is returned. When webhook_url is provided, the result is delivered as a POST request to that URL once the async job completes, fails, or is refunded.
