Best Lead Enrichment APIs in 2026
Enrichment is where credit pricing bites hardest: a mobile number can cost ten times an email, and unused credits may not carry over. Each line below is what the vendor's own pricing page said on 2 September 2026.
1
TAM Graph
Enrichment is included in the plan. GET /v1/company/{domain} returns the merged record for a domain across every dataset, and GET /v1/email-pattern/{domain} returns the naming pattern, generic inboxes and MX records. The email finder is unlimited under fair use at $199 a month, with no per-enrichment charge and nothing to expire.
2
FullEnrich
Waterfall enrichment. Its pricing page publishes a per-credit rate, charges ten credits for a mobile number against one for a work email, and rolls credits over for three months.
3
Dropcontact
Email finding and contact cleaning. Sold as monthly credit packages; API and MCP access come with the plan.
4
Hunter
Domain search and verification through one monthly credit allowance shared by the finder and the verifier.
