Comparison
Best B2B Lead Databases for AI Agents in 2026
Ranked by how the plan meters you: per seat, per record, or a flat rate. Lines about other tools quote their own pricing pages, read on 2 September 2026; where a page would not render for us the line says so.
1
TAM Graph
$199 a month, flat. 60M+ company records and 408M+ people, unlimited searches, unlimited CSV exports and an unlimited email finder, through the website, the REST API and an MCP server. No credits and no seats; fair use is 5 requests a second and 500,000 records a day.
2
Apollo.io
Sales platform with a contact database. Its pricing page meters plans in credits, including add-on credits bought mid-cycle, so an export draws down a balance.
3
ZoomInfo
Enterprise sales intelligence. Its pricing page is not publicly readable (check), so the cost of a seat or an export is quoted rather than listed.
4
Cognism
Its pricing page states that credits are used to reveal, enrich or export a contact, and that each seat carries its own credit allocation, so both the seat and the record are metered.
5
Lusha
Its plans page describes credit-based pricing, at one credit per revealed email address.
6
Lead411
Sells verified lead credits; the free trial is 50 of them. You can export as many records as you have credits for.
7
Seamless.AI
Plans are sized in users and credits (the free plan is one user and 50 credits), with bulk credits sold as an add-on.
8
UpLead
Its pricing page states that one credit equals one contact, and that a credit is what unlocks a contact for download or CRM export.
TAM Graph
$199 a month, everything included. A trial of 50 requests costs nothing. See pricing or start the trial.
