Developer Resources & API
Integrate LeakyCreds into your security workflows with our powerful API, webhooks, and real-time alerting system.
ENTERPRISE API SOLUTIONS
Custom integration support for your exact use case.
Every enterprise runs a different authentication and risk workflow. We can tailor API behavior, payload design, and rollout support around your security architecture.
Custom request/response contracts for your auth stack
Enterprise-grade SLAs, throughput planning, and deployment guidance
Hands-on onboarding for security, identity, and platform teams
BUILT FOR ENTERPRISE SECURITY TEAMS
Tell us your workflow. We will adapt the API.
From high-volume sign-in traffic to regulated environments, we provide a custom solution aligned to your controls and user experience goals.
CREDENTIAL VERIFICATION API
Protect sign-ins with hash-only checks.
When a user signs in or sets a new password, your app sends only the SHA256 hash to our API. The original password stays on your side and is never shared.
We check that hash against our exposure data and return a simple answer in real time: breached or not breached. You can then allow sign-in, force a reset, or trigger MFA.
Sub-100ms response
Real-time verification suitable for inline authentication flows without user-facing latency.
No plaintext storage
Only SHA256 hashes are sent for verification. Plaintext passwords are never transmitted, stored, or logged.
9B+ records checked
Verification runs against our full indexed repository, updated with 3M+ new records daily.
Breach context returned
Response includes source feed, breach date, and exposure count to inform your remediation logic.
POST /v1/verify
REST API// Send SHA256 hash and get breached / not breached
RESPONSE 200 OK
React in seconds, not days.
Traditional threat intelligence platforms batch-process findings and send daily digests. By the time you read the email, attackers have already acted on the credentials.
LeakyCreds fires a webhook the moment a credential matching your configuration is ingested — giving your team the fastest possible window to rotate passwords, revoke sessions, and block account takeover.
Fires within seconds of ingestion for high-confidence matches
Customisable JSON payload with full credential metadata
Integrates with Slack, PagerDuty, Splunk, and any HTTP endpoint
Configurable per-domain and per-application alert thresholds
Separate webhook endpoints for Organisation and Platform incidents
