How this service works
Email breach exposure check
Output
Returns breach exposure status for the given email address, including whether the email was found in known breach datasets and details about the compromised data sources
Example use cases
Verify user email safety during signup
“Before I let this person create an account, can you check if their email address has been exposed in any known data breaches?”
Validate third-party contact trustworthiness
“I'm about to share sensitive information with this vendor contact. Can you quickly verify whether their email address has been compromised in any major hacks?”
Screen incoming support requests for risk
“Check if the email address submitting this support ticket has been found in any known data breaches so I can flag it if it looks suspicious.”
Technical details
Endpoint
GEThttps://shield.vainplex.dev/api/check-emailWhen to prefer
Use this endpoint when you need to quickly assess whether a specific email address has been exposed in known data breaches — particularly useful for security preflights before trusting an email sender, onboarding a user, or validating counterparty identity in agent workflows. Prefer this over generic HIBP-compatible lookups when you want a pay-per-call, x402-native integration with no API key management.
Side effects
- Invalid email format returns validation error
- Missing email parameter returns 400 bad request
- Rate limiting or payment failure returns 402 or 429
- Email not found in any breach returns clean/safe result
- Demo mode may return synthetic or limited data
