Multi-Purpose
Requiems API vs API Ninjas
API Ninjas provides 135+ production-ready APIs covering finance, AI/vision, health, entertainment, transportation, and more β used by 600,000+ developers including Fortune 500 companies. Zero data storage policy.
Validation depth
API Ninjas has breadth but shallow validation APIs. Requiems API's email, phone, and IP validation goes deeper β SMTP checks, HLR lookup, threat scoring.
Real-time data
API Ninjas sources some data from static datasets. Requiems API does live checks for email, phone, and IP on every call.
Enterprise-ready billing
Both offer volume pricing. Requiems API adds per-team usage dashboards, per-key rate limits, and invoice-based billing.

Philosophy
API Ninjas is a data catalogue β thousands of facts served via REST. Requiems API is a validation and enrichment platform β we do live checks against real-world systems, not just database lookups. If you need historical earnings transcripts or animal facts, API Ninjas wins. If you need to know whether an email address actually receives mail right now, Requiems API is the right tool.
