https://api.lead.springbolt.app/resolve/keyword_to_lead

The flagship Springbolt X endpoint. Submit any keyword set: product terms, competitor brands, problem statements, buying-stage phrases, and Springbolt X resolves them against a rolling 8-day window of real search activity, returning the actual people who searched. Unlike Bombora or G2 (account-level surges, monthly latency), Keyword-to-Lead delivers person-level intent within hours of the search itself, the highest-converting window in the entire buying cycle. Output is ready to push directly into Meta, Google, LinkedIn, and CTV custom audiences, into email and SMS sequences, or into your CRM as priority outbound calls.
