Tools

• hibp_generate_domain_verification_dns_token ~219 tokens
  Generate the TXT record value required to verify domain control via DNS, creating or reusing the private HIBP domain-verification records needed for the request. Requires an authenticated subscription with domain-verification access.
• hibp_get_breach ~166 tokens
  Look up a single public HIBP breach by its canonical breach name, such as Adobe.
• hibp_get_breached_account ~392 tokens
  Search HIBP for breaches affecting a single email address. Requires an OAuth bearer token linked to an active HIBP API subscription; use domain and verification filters to refine the result.
• hibp_get_breached_account_range ~370 tokens
  Query the authenticated HIBP k-anonymity breached-account range endpoint with the first 6 characters of a SHA-1 email hash. Requires a subscription with k-anonymity access; compare each returned suffix with the remaining hash characters locally because a prefix alone cannot identify an account.
• hibp_get_breached_domain ~263 tokens
  Return breached aliases for a verified domain. This tool requires an authorized subscription via OAuth bearer token.
• hibp_get_latest_breach ~134 tokens
  Return the most recently added public breach currently loaded into HIBP.
• hibp_get_paste_account ~285 tokens
  Search for public pastes containing a single email address. Requires an OAuth bearer token linked to an active HIBP API subscription; run this separately from breached-account lookup.
• hibp_get_pwned_passwords_range ~365 tokens
  Query the public Pwned Passwords k-anonymity API with a 5-character SHA-1 or NTLM prefix and return matching suffixes with prevalence counts.
• hibp_get_stealer_logs_by_email ~295 tokens
  Return website domains historically observed in stealer logs for an email address. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_get_stealer_logs_by_email_domain ~306 tokens
  Return email aliases and associated website domains historically observed in stealer logs for an email domain. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_get_stealer_logs_by_website_domain ~299 tokens
  Return email addresses historically observed in stealer logs for a website domain. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_get_subscription_status ~176 tokens
  Return the current plan, quotas, rate limits, expiry, and feature flags for the active HIBP API subscription linked to the authenticated OAuth connection. Use it to confirm access before feature-dependent lookups.
• hibp_list_breaches ~318 tokens
  List public HIBP breaches, optionally filtered by domain, spam-list flag, and verification status.
• hibp_list_data_classes ~142 tokens
  List the data classes used across public HIBP breach models, such as email addresses or passwords.
• hibp_list_subscribed_domains ~224 tokens
  List the domains associated with the authenticated HIBP subscription.
• hibp_send_domain_verification_email Sends messages · ~226 tokens
  Send a domain verification email to an approved alias such as admin or security. Requires an authenticated subscription with domain-verification access.
• hibp_verify_domain_verification_dns_token ~192 tokens
  Complete domain verification by checking the expected HIBP TXT record on the target domain. Requires an authenticated subscription with domain-verification access.
