Web search API and crawler built for AI agents
Run natural-language or keyword queries against a large independent web index with filters for domain, date and category.
Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
Extract structured outputs such as company details, people and other entities for list building and data pipelines.
Agent observability, evals and governance for AI platform teams
Full GenAI spec support means traces from LangChain, LangGraph, CrewAI, Mastra, Pydantic AI, the Vercel AI SDK and any OTel-compatible stack land in the same view, with tokens, cost and cache accounted per span.
Score single outputs or entire conversations with an LLM judge, custom code or a workflow, run evals from a notebook or UI, and evaluate live production traffic in real time.
Simulated text and voice users push agents turn after turn in realistic scenarios, runnable locally and in CI, with tools, skills and MCP servers traced and mockable.
Route OpenAI, Anthropic, Google, Bedrock, Mistral and other providers through one endpoint using your own keys, with budgets per person, team and customer and around 11 microseconds of overhead.
