Example use cases

Technical details
Endpoint
POSThttps://mpp.orthogonal.com/happenstance/v1/research?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, multi-faceted profile of a real person and can provide a natural-language description with identifying details. Prefer this over structured lookup APIs when the input is descriptive rather than a precise identifier like an email or LinkedIn URL, and when you need rich output covering career, education, and personal interests rather than just contact data.
Side effects
- Insufficient identifying information in description leads to low-confidence or empty results
- Person is not found in available data sources
- Ambiguous description matches multiple individuals
- Rate limiting or quota exceeded
- Payment of 0.3 USDC not fulfilled, resulting in authorization error
