Strale.io offers free IBAN and email validation API for AI agents with no signup
Strale.io has released a free API layer for AI agents that provides five validation and utility capabilities without requiring signup or an API key. The service is designed as a trust layer for AI agents, returning structured JSON with quality scores and audit trails.
Available capabilities
The five free capabilities are:
- iban-validate
- email-validate
- dns-lookup
- url-to-markdown
- json-repair
Usage example
You can test the IBAN validation with this curl command:
curl -X POST https://api.strale.io/v1/do \
-H "Content-Type: application/json" \
-d '{"capability_slug": "iban-validate", "inputs": {"iban": "DE89370400440532013000"}}'MCP server integration
For users of Claude or Cursor, there's an MCP server available at https://api.strale.io/mcp. This uses Streamable HTTP and requires no installation.
Full platform context
The complete Strale.io platform offers over 270 capabilities including company registries, sanctions screening, and web scraping tools. However, the free tier with these five capabilities is described as genuinely useful on its own for AI agent validation tasks.
