The company research API for AI agents
Query companies programmatically and receive structured, sourced answers that your own agents or applications can consume.
Match against a maintained business index or search the open web when the company you want is not in any list.
Define a brief with sector, size, location, and capability filters, and get back candidates rated for fit.
Every answer includes its origin, so findings can be verified and audited rather than accepted blindly.
Real human data for AI training, evals, and research — in minutes
Access hundreds of thousands of vetted participants across 40+ countries, with demographic screening so you can target the exact population your study or evaluation needs.
Purpose-built workflows for collecting human preference judgments, red-teaming feedback, and benchmark ratings for large language and multimodal models.
Programmatic access that lets engineering teams pipe real human feedback into model evaluation and agent workflows without leaving their own tooling.
Launch a study in minutes, set quotas and reward levels, and scale sample sizes up or down while keeping response quality consistent.
