{"jsonrpc":"2.0","id":1,"method":"tools/list"}sos_search — Search US state business-entity registries (Secretary of State) by company name — FL, NY, CO, OR, CT, PA, and TX (Comptroller franchise-tax registrations). Returns each match with entity number, legal name, entity type, status, formation date, principal address, registered agent (an agent's address only when the agent is a business), and the state source, plus data_as_of per state. Name matching is "starts with"; if nothing starts with the name it retries as "contains". Omit state to search all seven at once. Use the entity_number with sos_entity for officers. Sourced from each state's official registry publications.sos_entity — Full registry record for one business entity by state and entity number: legal name, type, status, formation date, principal address, registered agent, and officers/directors/managers as [{name, role}] where the state publishes them (FL up to six officers, CT principals, PA parties, NY chairman/CEO, OR authorized representative; CO and TX publish none). Individuals' addresses are never included. Get entity_number from sos_search or sos_new_entities.sos_new_entities — Business entities newly formed in one state since a date — new LLCs, corporations and partnerships, newest first (formation dates from `since` through today; delayed-effective future dates are left out), with entity number, name, type, formation date, principal address and source, plus data_as_of. Optional name and entity-type filters. Deterministic order (formation date, then entity number). Florida reaches back 70 days; the other states any date. Use for new-business lead lists and formation monitoring.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
