Use tool ↗About Bytemine
Bytemine sells B2B prospect data: it claims 135M+ contacts, 80M+ mobile numbers and 10M+ company records, searchable in a no-code app that looks up contacts, builds lists, enriches uploaded CSVs and validates emails, with an autonomous LinkedIn prospecting agent on top. The developer side is the unusual part: REST API families for contacts, lookalikes, ICP building, crawling and signals, plus an MCP server so Claude, ChatGPT or Cursor can query the data directly, and an agent storefront that publishes prices and payment instructions for software buyers. Plans are credit-based, one credit per complete contact, from a free 100 credits a month up to $2,500.

Pros & cons of Bytemine
A data vendor built for developers and agents first: the APIs and MCP server are the product as much as the web app, and an agent can buy access without a human signup. A $250 Starter plan now sits below the old $1,000 entry, which opens it to small teams, though per-credit cost only drops sharply from the Business tier up.
Pros
- Unlimited seats instead of per-user pricing
- REST API families and an MCP server, not just a web app
- Paid entry is now $250/month, with month-to-month billing
- Free tier of 100 credits a month needs no card
Cons
- Starter credits cost $0.025 each, 2.5x the Business-tier rate
- Coverage and accuracy claims are the vendor's own with no third-party benchmark
- No legal entity, address or country found on the site
- The agent storefront sells access without a human in the loop, which is a governance question for buyers
Best for
- Engineering teams wiring enrichment into their own pipeline
- Agent builders who need a purchasable data source over MCP
- Sales orgs that would otherwise pay per seat on a legacy data vendor
Not for
- Solo sellers who need only a few dozen contacts a month beyond the free 100
- Buyers who need compliance paperwork and a named legal entity up front
Watch out: Buying contact data brings GDPR and CCPA obligations onto you as the controller — confirm sourcing and opt-out handling before you load it into an outreach tool.
