Changelog

Stay up to date with the latest MoltSets updates and features.

Beta

MoltSets is in beta. Functionality may change at any time without notice. Uptime is not guaranteed during beta.

September 2026

September 22, 2026 - [Update] State filter accepts full names and abbreviations

  • The state filter on search_people and search_companies now accepts a full state name or its abbreviation, so "Texas" and "TX" both work. exclude_state accepts the same values. Lists can mix both forms, for example state: ["Texas", "FL"]. All other location filters still need exact full names, including country and city.

September 22, 2026 - [Update] Positive filters on search_people and search_companies now accept lists

  • Every positive filter now accepts a list of values, matching how exclude_* filters already worked. A list is OR within its field, AND across fields, so title: ["CEO", "CMO"] with country: ["United States", "Canada"] returns (CEO or CMO) in (US or Canada) as one ranked search instead of several separate ones.

September 21, 2026 - [Update] Documentation for ChatGPT, Grok, Cursor, and more

September 18, 2026 - [Change] New personal email endpoints

  • We've added US-only versions of the two personal-email endpoints. The old endpoint names still work for now but are deprecated and will be removed — we'll announce the date in advance. Same data, same format — non-US records are now filtered out. To migrate, add _usa to the end of the tool or route name:

    • linkedin_to_personal_email → linkedin_to_personal_email_usa

    • linkedin_to_best_personal_email → linkedin_to_best_personal_email_usa

September 18, 2026 - [Fixed] Resolved personal-email lookup consistency issues across endpoints

  • All personal-email lookups now read from the same source. Previously the same LinkedIn URL could return an email from one endpoint and "not found" from another.

September 16, 2026 - [Update] API calls now require User-Agent

  • API calls now require User-Agent to be added to the header in order for a successful call to be made. API connections created prior to September 16 will experience a 403 error until User-Agent is added to the header. More information

September 15, 2026 - [Added] $397 mid-tier plan introduced

  • We've introduced a new mid-tier plan for $397 per month that has 10x the rate limits of the $97 plan. At the same time, the $997 plan's rate limits have also increased to be 15x those of the $97 plan.

September 11, 2026 - [Added] MCP now allows for native and CLI connections

  • The MoltSets MCP now accepts http:// redirect URIs for loopback addresses (127.0.0.1, ::1, localhost), in line with RFC 8252 for native and CLI applications. Previously only https redirect URIs were accepted, which made the connection unworkable for command-line tools that listen on a local port rather than hosting HTTPS. More information

September 11, 2026 - [Update] Search endpoint Fair Use accounting

  • search_business_email_by_name, search_linkedin_profile, and search_business_profile_by_name now correctly count against the search Fair Use Policy (FUP) limit, consistent with other search endpoints. Usage from these endpoints was previously not being counted, which has been corrected.

September 10, 2026 - [Fix] Fixed SMS sign-up/login issue

  • Fixed the issue with SMS sign-up and login whereby users were not receiving the SMS containing their access code. SMS sign-up remains restricted to North American numbers at this time.

September 9, 2026 - [Update] No-result lookups now return 200, not 404

  • No-result lookups now return 200 with status: "not_found" and full metadata instead of a 404, on both single and batch calls; 404 is reserved solely for tool_not_found. MCP responses also gain a one-line note clarifying that a miss is a normal, uncharged outcome rather than an error.

September 9, 2026 - [UX Update] 'Terminal' input prompt changes

  • Renamed the dashboard's "Ask me anything about MoltSets" input prompt to "Learn more about MoltSets — type /help to get started," since the original text referenced a sidebar prompt list that's since been removed and left users unsure how to use the input.

September 9, 2026 - [Removed] UGC program will not be launching

  • The UGC program previously mentioned in the MoltSets app will not be launching. We had originally planned to introduce it once the beta period ended, but we've since decided against it. The program never became active.


August 2026

August 25, 2026 - [Update] Changes to search_people

  • The following parameters have been added to search_people, enabling users to exclude variables from search results: exclude_company_domain, exclude_country, exclude_state, exclude_industry, exclude_seniority, exclude_employee_range.

August 24, 2026 - [Fix] Fixed a LinkedIn URL parsing bug caused by unsupported characters

  • Fixed a LinkedIn URL parsing bug that could truncate slugs at unsupported characters, sometimes matching and charging for the wrong profile. Slugs are now validated in full (including international characters) instead of silently cut short.

August 21, 2026 - [Update] Updated Terms of Service

  • MoltSets has updated its Terms of Service. If you do not agree with the updated Terms, please cease use of MoltSets immediately.

August 12, 2026 - [Update] External tokens no longer apply to email addresses

  • External token usage no longer applies to email addresses. "External tokens" have now been renamed to "Phone tokens" and only apply to mobile phone numbers. Phone numbers cost 1 token instead of 10. The price of purchased tokens has been adjusted accordingly (read: $5 buys you 10 tokens now instead of 100, etc.). Please see Phone Tokens for the current price of ad hoc phone tokens.

August 12, 2026 - [Update] 'Personal email address' endpoints no longer available on the $997 plan

July 17, 2026 - [New] Company Accounts

  • If you sign up with an email domain that already has a MoltSets account, we no longer create a duplicate account. Instead, you'll verify your email and your request will be routed to your account owner for approval — with a status page so you can track where things stand while you wait.

July 15, 2026 - [Fixes] Subscription bugs fixed

  • Two subscriptions bugs have been fixed; one that prevented users from purchasing the $997 plan and another that affected users who were attempting to resolve past due subscription payments.

  • Mobile phone numbers now return a last_validated_at date to show the date that the number was last validated.
