# Claidex > The failure record for biomedicine. Claidex publishes mechanistic post-mortems on terminated and withdrawn clinical trials. Every claim traces a drug's biological hypothesis to where it broke in humans. Preprint Watch cross-references new bioRxiv preprints against this clinical failure record daily. ## Core pages - [Overview](https://app.claidex.com/): Agent-first workspace and recent failure activity - [Failure Claims](https://app.claidex.com/claims): Indexed post-mortems on terminated clinical trials - [Preprint Watch](https://app.claidex.com/preprint): bioRxiv signals checked against clinical failures - [API Docs](https://app.claidex.com/dashboard/api): REST API reference and live examples - [MCP Docs](https://app.claidex.com/mcp): Model Context Protocol server for AI clients ## Data products - [Claidex Failure Atlas](https://app.claidex.com/claims): Queryable failure dossiers with Mechanism Risk Scores - [Failure Atlas DOI](https://doi.org/10.5281/zenodo.20301162): Zenodo dataset for citation and bulk download - [REST API](https://app.claidex.com/api/v1/failures): JSON endpoint for programmatic access ## Citation and usage - License: [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) - Cite individual claims from their page citation panel (APA, BibTeX, RIS, DataCite) - Attribution: Claidex (https://claidex.com) - Contact: https://claidex.com ## Optional - [Extended documentation](https://app.claidex.com/llms-full.txt)
