Endpoints cover company enrichment, research & discovery, competitor and sales-signal analysis, lead qualification, person enrichment & search, hiring and job-change signals, intent signals, domain/tech intelligence, KYB entity verification, news sentiment, outbound personalization, and real-time validation/normalization utilities (email, phone, URL, address, domain resolution, NAICS). Every response is normalized JSON built for agent-to-agent workflows. All endpoints are live and x402-validated (indexed on Agentic/Bazaar via real settled USDC payments on Base). Per-call pricing starts at $0.005 depending on the endpoint. Additional intelligence agents are actively in development and will ship under the same api.qonoro.ai base.
