What is MoltSets?

MoltSets is an identity resolution API. You give it a single piece of data, such as an email address, LinkedIn URL, IP address, or hashed email, and it returns enriched contact and company information. Every tool uses the same request and response structure, so once you have made one call you know how to make all of them.

Do I use the API or the MCP?

Both are front doors to the same product, on the same account, data, and credit balance. The REST API is for code: backends, scripts, and platforms like Clay or n8n that call it over HTTPS. The MCP server is for AI assistants: add it to a client like Claude and the model can call MoltSets tools directly in a conversation. If you are not building your own software, the MCP is the faster way to start because there is nothing to build.

What can I look up?

Business, personal, and best-available emails, mobile phone numbers, full LinkedIn and company profiles, company-from-IP, and hashed-email resolution, plus people and company search. Every tool follows the same request and response shape, and the full list with parameters and response schemas is in the API reference.

Does MoltSets really have unlimited data?

Your tokens are unlimited in the sense that they never expire. There's no monthly reset and no rolling expiry, so you can keep using your balance for as long as you like. What we do apply is a per-minute request limit and a daily results limit, both set by your plan, to keep usage fair across everyone. So "unlimited" refers to the lifetime of your tokens, not an uncapped daily volume.

Are the emails and phone numbers valid?

We only return emails and phone numbers that we have previously verified. We don't generate addresses from name-and-domain patterns or hand back unverified guesses, so anything you receive has passed a verification check rather than being inferred. If we don't have a verified contact for someone, we return nothing instead of a guess. Verification reflects the point at which we last checked a contact, so a small number may have changed since then if someone has moved roles or switched numbers.

Which regions does MoltSets cover?

At launch we provide US data only. Coverage for [UK / EU / other regions] is on our roadmap, and we currently expect to begin expanding around Q4. Until then, lookups for contacts outside the US return no results rather than partial or unverified data.
