Example prompt: Can you check if this LinkedIn URL is valid and accessible, and tell me what type it is (profile, company, or job): https://www.linkedin.com/in/jane-doe-12345/?

## When to prefer this

Use this endpoint when you need to programmatically verify that a LinkedIn URL is properly formed before storing it in a database, sending it to another service, or displaying it to users. Ideal for lead enrichment pipelines, CRM integrations, or any workflow that ingests user-supplied LinkedIn URLs and needs to distinguish profiles from company pages or job listings.

## Known failure modes

- Non-LinkedIn URL submitted — may return valid_format: false
- Malformed URL string — parser may fail to extract slug
- LinkedIn page may be private or removed — accessible: false even if format is valid
- Network timeout when checking accessibility — accessible may be unreliable
- Rate limiting or payment failure — returns x402 payment required error
