Prospect enrichment in 2026 goes beyond appending job titles and emails. Sales teams want real-time web signals, content activity, and market context layered onto lead records. The best enrichment APIs combine firmographic data with live web intelligence. We ranked five APIs on data breadth, real-time signals, API design, and cost.
Scavio wins for web-signal enrichment. It adds real-time Google, YouTube, Reddit, Amazon, and TikTok data to prospect records, showing what prospects are searching for, discussing, and publishing across platforms. At $0.005/credit, it layers web intelligence onto leads at a fraction of traditional enrichment costs.

Why Scavio Wins
- Web-signal enrichment adds context that traditional enrichment misses: what prospects search on Google, discuss on Reddit, and watch on YouTube.
- At $0.005/credit, enriching 1K leads with web signals costs $5 versus $15K+/year for ZoomInfo or variable per-enrichment fees from Clearbit.
- Apollo and ZoomInfo are necessary for contact data (emails, phones, job titles). Scavio complements them with web intelligence, it does not replace them.
- MCP integration lets AI SDR agents enrich leads with real-time web data during outreach sequence creation.
- Credit-based pricing with no annual contracts means enrichment costs scale with pipeline size, not a fixed annual commitment.
