How this service works

Email finding, verification, and company enrichment for outreach and lead generation.

Output

Returns a JSON object containing email verification results (deliverability, format validity), professional contact details (name, job title, seniority, department), and company enrichment data (company name, domain, industry, size, location) sourced from Hunter.io, along with x402 payment metadata confirming the settled USDC amount.

Example use cases

Sales lead enrichment before outreach

“I have a lead's email address — sarah.jones@techcorp.io — can you verify it's real and pull back her job title, company info, and anything else useful before I reach out?”

Validate CRM contact data

“We imported a bunch of contacts into our CRM and I want to verify this email is deliverable and get the latest company info: michael.chen@startupxyz.com — can you run enrichment on it?”

Identify anonymous inbound email sender

“Someone emailed us at support from alex.rivera@globalventures.com — can you figure out who this person is, what their role is, and what their company does so I can route the inquiry properly?”

Endpoint

POSThttps://hunter.x402.paywithlocus.com/hunter/combined-enrichment

When to prefer

Choose this endpoint when you need a single API call that combines both email verification and company/contact enrichment in one shot, rather than calling separate verify and enrich endpoints. It is ideal for sales and marketing automation workflows where you have an email address and want a full professional profile. Prefer this over raw Hunter.io direct access when you want pay-per-use USDC micropayment billing via the x402 protocol without managing a Hunter API subscription.

Side effects

Email address not found in Hunter database — data object may be empty or sparse
Invalid email format causes input validation failure
Email domain does not exist or is unresolvable — verification returns invalid status
Hunter.io upstream rate limit or outage causes timeout
Insufficient USDC balance or x402 payment authorization failure prevents the call from completing
Newly registered or very obscure domains may return no company enrichment data
