Check whether a public web source contains claimed text using exact, normalized, or deterministic fuzzy matching, with passage context and retrieval provenance.

Probe a public HTTPS URL and recommend the lowest-cost likely retrieval strategy (plain HTTP, browser render, PDF/feed/JSON/XML parser, authentication required, blocked, or unsupported) with the evidence that produced the recommendation.

Compare Apify datasets and get a clean change feed showing only new, removed, and modified records. Perfect for scheduled scrapers, price monitors, lead feeds, SEO checks, and automation workflows in Make, Zapier, n8n, AI agents, and custom APIs.
