# Service Contracts Content providers and CDNs negotiate the terms of a delivery contract in the capacity marketplace that defines the service schedule, footprint bitrates and SLA needed. Contracts incorporate multiple sources of truth such as signed delivery requests, cache node logs (masked for personal information as in [draft-ietf-cdni-logging-extensions](https://datatracker.ietf.org/doc/draft-ietf-cdni-logging-extensions/)) which are verified by the challenger network for payment settlement to participating nodes, and refunded in case of a service failure. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
