How this service works
Check whether an email address appears in known data breaches. Returns breach count, source names, dates, and exposed data types (passwords, emails, etc). Call before trusting a new user identity or granting elevated access.

Example use cases
Example prompt
“Can you check if the email address john.doe@example.com has ever shown up in any known data breaches, and tell me which ones and what type of data was exposed?”
Technical details
Endpoint
POSThttps://atq6wtkp6k.execute-api.us-east-1.amazonaws.com/prod/v1/payg/breachWhen to prefer
Use this endpoint when you need to check whether a specific email address has appeared in known public data breaches, particularly when you need breach-level detail (name, domain, date, data classes). Prefer this over generic HIBP-style checks when operating within the RelayShield security suite for consistent risk scoring alongside wallet and URL checks.
Side effects
- Invalid or malformed email address returns validation error
- Email not found in any breach database returns empty breaches array with breach_count 0
- API gateway timeout or cold start may cause temporary 5xx errors
- Payment failure (x402) if USDC balance is insufficient or payment header is missing
- Rate limiting if too many requests are sent in quick succession
