Strale

strale-io/strale

Strale gives your AI agent 290+ pre-scored API capabilities spanning company lookups, VAT validation, IBAN checks, compliance screening, Web3 wallet risk scoring, and more across 27 countries. Every capability ships with a Strale Quality Score (0-100) derived from live quality and reliability testing, so you can set minimum thresholds and avoid flaky tools. Five endpoints (email validation, DNS lookup, JSON repair, URL-to-markdown, IBAN validation) work without an API key. The rest require signup with €2 in free credits. Deploy via Streamable HTTP with zero local setup, or run stdio locally with npx. Reach for this when you need turnkey agent skills for KYB, due diligence, or financial validation without managing credentials or uptime yourself.
