# TrueBiz > TrueBiz automates merchant risk assessment by analyzing a business's internet footprint. Its Web Presence Review API scores a merchant's legitimacy and risk from a domain plus submitted business details, and its Monitoring API continuously watches domains and raises alerts. Used by payments providers and financial institutions to streamline underwriting and ongoing merchant due diligence. Authentication: all requests require an API key in the `X-API-KEY` header (a PropelAuth bearer JWT is also accepted). Base URL: https://ae.truebiz.io. Async endpoints return a `request_id`; results are retrieved by polling the history endpoints (submit-and-poll, no webhooks). List endpoints paginate with `limit`/`offset`. ## APIs - [TrueBiz Web Presence Review API](https://ae.truebiz.io/api/v1/docs): merchant web-presence review, blocklist, website status, monitoring, industry discovery, and fraud search. ## Specs - [OpenAPI 3.0.2](https://ae.truebiz.io/api/v1/openapi.json): the machine-readable API definition (19 paths, 23 operations). ## Products / operation groups - Web Presence Review (`POST /api/v1/company/search`, `POST /api/v1/company/async/search`): assess a merchant from a domain + submitted business details. - Website Status (`POST /api/v1/website/status`): check whether a merchant website is reachable. - Blocklist (`GET/POST/DELETE /api/v1/company/block`, `POST /api/v1/company/evaluate`): manage and evaluate blocklisted domains. - History (`GET /api/v1/history/company`, `GET /api/v1/history/company/{request_id}`, `GET /api/v1/history/industry`, `GET /api/v1/history/combined_lookups`): retrieve stored review results. - Monitoring (`POST /api/v1/monitoring/start`, `GET /api/v1/monitoring/domains`, `GET /api/v1/monitoring/alerts`): continuous domain monitoring and alerts. - Industry Discovery (`POST/GET /api/v1/industry-searches`): discover businesses by industry. - Fraud Search (`POST/GET /api/v1/fraud-searches`): run fraud-oriented searches. ## Docs - [API Reference (ReDoc)](https://ae.truebiz.io/api/v1/docs) - [Documentation](https://docs.truebiz.io) - [Blog](https://truebiz.io/blog) - [Contact / Support](https://truebiz.io/contact-us) - [Login / Sign up](https://app.truebiz.io/) ## Artifacts (API Evangelist enrichment) - [Authentication profile](authentication/truebiz-authentication.yml) - [API conventions](conventions/truebiz-conventions.yml) - [Error catalog](errors/truebiz-problem-types.yml) - [Lifecycle](lifecycle/truebiz-lifecycle.yml) - [Data model](data-model/truebiz-data-model.yml) - [Conformance](conformance/truebiz-conformance.yml) - [MCP (candidate)](mcp/truebiz-mcp.yml)
