Moltsets
B2B search and enrichment API for AI.
From $27/mo Free tier MCP server API
Bottom line
B2B enrichment APIs with a free 1,000-record plan. Paid starts at $27/mo for unlimited enrichment under fair use.
Stands out for: Flat plans from $27/mo with unlimited enrichment records, not a per-lookup credit meter.
Watch out for: Unlimited is rate-limited (5k requests per 5 hours on $27). Extra mobile tokens start at $0.20 each.
Overview
Moltsets sells contact enrichment APIs: work email, personal email, carrier-matched mobile, people and company search, email validation, and reverse email lookup. Free covers 1,000 enrichment records for the life of the account and 1,000 requests per 5 hours, plus 10 mobile tokens. Paid starts at $27 per month for unlimited records and 5,000 requests per 5 hours. $97, $397, and $997 raise those rate limits. Extra mobile tokens start at $0.20. Fair-use rules apply to unlimited plans.
Developers pick Moltsets to stop buying credits per lookup. MCP is documented at developer.moltsets.com. Bulk flat files are a separate conversation. There is no numbered day trial beyond the free plan. This is an API console, still marked closed beta on the pricing screen. If you need a visual sequencer, look elsewhere. Buying $27 is self-serve.
