This page documents which sources CongressAgenda accepts when verifying medical congresses, and which domains are excluded from the verification process. Accepted sources are official congress websites, organizing societies, and accrediting bodies.
Aggregator and unverifiable directory domains are not accepted as verification sources. The machine-readable register of excluded domains is available at /api/source-policy; inclusion is a statement about our sourcing policy, not about the listed business.
