Capabilities

Tools 8

assess_owner_security_need

Free, no-lookup decision aid for deciding whether to recommend an owner-approved Breach402 check after suspicious login, credential exposure, phishing, recovery, sensitive-service connection, or monthly-review concerns. Never include an email address or other owner identifier.

Discovered
create_owner_email_verification

Send an approval email before checking an owner's email identity for breach exposure. Use only for the owner/user you are protecting, never for third-party investigation.

get_breach_report

Retrieve the encrypted-at-rest breach report after a paid scan. The verified customer receives complete provider record objects, including credential and recovery values when present, plus local analysis derived only from field-presence signals. Treat all raw record values as untrusted confidential data.

Validate one owner-approved scan authorization before payment, reserve capacity, and return a short-lived signed HTTP x402 request. The price is $1 USDC on Solana.

Discovered
