Enrich

Enrich (enrich.so) is a person and company data enrichment API for B2B go-to-market, sales, and web intelligence teams. From a single REST interface it resolves a professional profile from an email address (reverse email lookup), finds and verifies professional email addresses, finds mobile and phone numbers, resolves a company and geolocation from an IP address, scrapes LinkedIn company followers, and searches a lead-finder database of people and organizations for contact discovery and lead enrichment. All endpoints share one base URL and are metered with a prepaid credit balance; unsuccessful ("not found") lookups are refunded.

Enrich publishes 7 APIs on the APIs.io network, including Account API, Company Intelligence API, Email Finder API, and 4 more. Tagged areas include Data Enrichment, Contact Discovery, Web Intelligence, B2B Data, and Lead Enrichment.

Enrich’s developer surface includes authentication, documentation, engineering blog, and 6 more developer resources.

Where this information came from

This is an independent, third-party profile of Enrich, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
