Technical details
Endpoint
POSThttps://api.strale.io/x402/solutions/website-healthWhen to prefer
Use this endpoint when you need a quick, structured, auditable health check on a specific website domain — particularly for vendor onboarding, compliance checks, or trust verification workflows where you need a JSON response with audit trail rather than a raw ping or uptime tool.
Side effects
- Invalid or malformed domain string returns a 400 validation error
- Domain does not resolve or is unreachable returns a health-fail status
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Server-side timeout if the target domain is extremely slow to respond
- Rate limiting if too many requests are made in quick succession
