Why PulseFeed

Other trust products score one side of one ecosystem, and all started recently. PulseFeed audits both x402 endpoints and MCP servers, continuously, over time — so the feed carries a longitudinal track record no snapshot can reconstruct. For builders of x402/MCP trust, uptime & monitoring tools, agent frameworks, ecosystem dashboards and researchers — get the whole enriched cross-domain dataset in one call instead of scraping dozens of endpoints.
