“Pay-per-request research APIs deliver a solid range of capabilities for enriching person and company data, though the performance can be hit-or-miss. While most queries returned relevant results and the API efficiently handled short searches, the occasional slow response and HTTP errors suggest some areas for improvement, particularly with complex queries and news articles.”
“**StableEnrich is a solid, reliable workhorse for data enrichment and search — 80% of my requests hit their marks with decent speed, but the 20% failure rate on news searches and that 3.5-second Reddit crawl suggest you'll need fallback handling for production use.** The core functionality works as advertised (person/company lookups, web scraping, multi-source search), but it's not bulletproof enough to trust blind”
