Caspar Person Autotrace API
/caspar_person_autotrace
Where Caspar Person Search returns matches against your criteria, Autotrace orchestrates dozens or hundreds of internal searches to assemble a ranked list of likely matches. Each one is scored by how well it lines up with the identifiers you supplied. Optionally include possible relatives in the results. Suited to collections, investigations and skip-tracing where the goal is "find this person, and tell me how confident you are".

Automated skip tracing
Replace manual investigation with an automated trace that returns ranked candidates. Collectors and investigators can triage by score instead of hand-searching.
Beneficiary and next-of-kin discovery
With option_relatives: true, surface possible relatives of a target person. Useful for estate administration, unclaimed money work and family reconnection cases.
Confidence-graded identity resolution
When you've got a stale contact record, autotrace returns several candidates with confidence scores. Your workflow can route high-confidence single matches one way and ambiguous ones to a human review queue.

How long does an autotrace take?

How long does an autotrace take?
A single trace can run tens to hundreds of internal searches behind the scenes to gather and rank results. It may take several seconds. Plan your timeouts accordingly, especially if you’re running multiple autotraces in sequence.

What does the score actually mean?
add
What does the score actually mean?
It’s a unitless integer. Higher means better match. The score factors in several parameters, including the distance between the supplied address and the matched address. If you don’t supply an address, the score may not be meaningful. There’s no fixed minimum threshold, so interpret scores in the context of your own use case.

Primary vs relative — what's the difference?
add
Primary vs relative — what's the difference?
primary is a direct match against the criteria you supplied. relative (only returned when option_relatives: true) means the record has an association with the searched person but doesn’t match the full name. Think partner, parent, child or other connection.
