How this service works

Person Enrichment: Enrich one person by professional-profile URL, or by full name plus company domain or company name. Returns the work email (verification status plus all variants found) and the full public profile: headline, current role, experience history, education, skills, location. Unfinished lookups return status "pending"; a settled no-match returns 404 and is not charged. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/enrich_person.

Output

A JSON object containing: work email address(es) with verification status and all discovered variants; full public professional profile including headline, current role and company, full experience history, education, skills list, and location. Unfinished lookups return status 'pending'. If no match is found after processing, a 404 is returned and the call is not charged.

Example use cases

Sales lead email discovery

“I need to reach out to the head of engineering at Notion — can you find their work email and current job title? Their name is Linus Lee and the company domain is notion.so.”

CRM record enrichment from LinkedIn

“We have a new prospect — their LinkedIn is linkedin.com/in/melissastewart. Can you pull their full professional profile including current role, company, past experience, and education so I can update our CRM?”

Conference speaker background lookup

“I'm preparing for a meeting with Sarah Chen who works at Databricks — can you find her headline, job history, skills, and work email using her name and company domain databricks.com?”

When to prefer

Choose this endpoint when you need to enrich a specific individual's professional profile or discover their work email, especially when you have a LinkedIn URL or a name+company combination. It is well-suited for sales prospecting, CRM enrichment, and pre-meeting research. Prefer it over generic web search when you need structured, verified output (email verification status, role history) rather than raw text. Note: phone and personal email lookups are not available; use a different provider for those.

Side effects

404 returned when no match is found after settlement (not charged)
Status 'pending' returned when lookup is still processing — caller should retry
400 returned if want_phone or want_personal_email is set to true (unsupported)
Ambiguous name+company combinations may yield wrong person or no result
Profile data may be incomplete if the person has limited public presence
Payment failure via x402 if wallet has insufficient USDC on Base

Input

Schema · Request body

Field	Type	Description
full_name	string	Person's full name. Required unless profile_url is supplied; the email search also needs a company key.
want_email	boolean	Request the work email (default true). Needs full_name plus company_domain or company_name.
want_phone	boolean	Must stay false — phone lookup is not available and returns a 400.
profile_url	string	Professional-profile URL (e.g. LinkedIn) — the richest key; alone it yields a profile without an email.
company_name	string	Company name — alternative to company_domain for the email search.
company_domain	string	Company domain, e.g. stripe.com — disambiguates the email search.
want_personal_email	boolean	Must stay false — personal-email lookup is not available and returns a 400.
