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.

Clean, validated invoice data for any ERP
AI pulls headers, totals, line items and references from invoices, receipts, purchase orders and statements into structured data.
IF checks, formulas and conditional logic catch wrong totals, missing fields and bad supplier IDs, or transform data on the fly.
Map any supplier alias on a document to your internal supplier ID once, and Harold applies it automatically from then on.
Shape exports to match your ERP, finance team or Zapier flow with CSV, Excel, JSON and webhook output templates.
