How this service works
Search for a person using a variety of parameters such as LinkedIn slug, LinkedIn URL, or their current company information. Returns profile data for the person if found.
Output
Returns matched LinkedIn profile data including name, current job title, employer, location, education history, and optionally deep education details. Results are sorted by best match and limited to the requested number of profiles. May include cached or live-fetched LinkedIn data depending on the liveFetch setting.
Example use cases
Lead enrichment from email
“I have an email address for a sales prospect — sarah.johnson@techstartup.io — can you pull her LinkedIn profile and professional details so I can personalize my outreach?”
Find decision maker at target company
“I'm trying to reach the Head of Product at Stripe. Can you look up that person's LinkedIn profile and current role using Stripe's company domain?”
Verify prospect identity before outreach
“Before I reach out, can you confirm whether this LinkedIn URL is correct for our contact — https://www.linkedin.com/in/markrobinson-cto — and pull their current job title and company?”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/fiber/v1/kitchen-sink/personWhen to prefer
Use this endpoint when you need to look up a specific professional's LinkedIn profile data using any combination of identifiers (name, email, LinkedIn URL, company). It is especially well-suited for B2B lead enrichment, sales prospecting, and verifying professional identity. Prefer it over generic web search when you need structured LinkedIn-style profile data with fields like job title, employer, and education. The fuzzy search option makes it resilient to minor name variations, and the companyIdentifier field significantly boosts match accuracy when the target company is known.
Side effects
- Person not found in database — returns empty results or no match
- Ambiguous name with no company context — low-confidence or multiple unrelated matches
- LinkedIn URL or slug is stale or incorrect — no result returned
- liveFetch enabled but LinkedIn rate-limits or blocks the request — slower or failed response
- Invalid profileIdentifier shape — API rejects the request with a schema error
- Company identifier not recognized — reduces match accuracy
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| jobTitle | object | |
| liveFetch | boolean | Whether to fetch the freshest copy of the found profiles's LinkedIn data (costs extra). If omitted or set to false, we'll give the cached data present in our database. The boolean flag is deprecated and will be removed in future. Please use the object instead. |
| personName | object | |
| companyName | object | |
| fuzzySearch | boolean | Whether to use fuzzy search on names, job titles and other parameters. This is good if you are not sure about the exact name or job title. |
| numProfiles | integer | The maximum number of profiles you want to fetch. Profiles are sorted by best match first. |
| emailAddress | string | The email address of the person to search for |
| companyDomain | object | |
| companyIdentifier | string | The company the profile is currently working at. If provided the accuracy of the lookup increases. You do not need to pass in any other company parameters if you pass this. |
| forceCompanyMatch | boolean | Whether to strictly match the company. If true, we will strictly lookup prospects which belong to given company details. |
| profileIdentifier | object | Object identifying the profile — NOT a bare string. Shape: { "identifier": <id type>, "value": <the id> }, e.g. {"identifier":"linkedinUrl","value":"https://www.linkedin.com/in/jdoe"}. If provided and correct, no other fields are needed. If you are unsure of the identifier type, omit this and instead pass emailAddress, or personName together with companyName / companyDomain. |
| getDetailedEducation | boolean | Whether to include deep details about each educational item, like the school's LinkedIn URL, website, location, etc. That'll be put in the detailedEducation array. This slows down the API call, so only enable this if you need it. |
| getDetailedWorkExperience | boolean | Whether to include deep details about each work experience item, like the company's LinkedIn URL, website, location, etc. That'll be put in the detailedWorkExperience array. This slows down the API call, so only enable this if you need it. |
