Cloud browsers and web APIs for AI agents
Spin up scalable, sandboxed headless browsers on demand and drive them with Playwright, Puppeteer, Selenium, or the Stagehand framework.
Find relevant websites from a single query and convert any URL into clean HTML, JSON, or markdown built for LLM context.
Authenticate agents and get through login walls, CAPTCHAs, and anti-bot systems so workflows do not stall mid-task.
Inspect sessions with live view, replay, structured logs, and debugging across prompts, model calls, and browser actions.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
