Query in plain English

No schema. No joins. Ask for exactly what your agent needs — Watt resolves the query against 81,000+ signals per person.

query.ts

const result = await watt.query(
  'Series B SaaS CTOs in NYC actively researching CRM tools'
)

// Structured results with full signal payload
console.log(result.records[0])
// → { job_title_inferred: 'CTO', funding_stage: 'Series B',
//     search_intent_category: 'CRM software',
//     location_metro_area: 'New York Metro', ... }

Export production-ready lists

Push enriched records directly to your CRM, data warehouse, or downstream agent — or pull them via MCP.

export.ts

// Push to CRM
await watt.export({
  query: result,
  destination: 'salesforce',
  mapping: {
    job_title_inferred: 'Title',
    funding_stage: 'Account_Stage__c',
