## Christian evidence APIs

Source-labelled BSB/WEB scripture evidence and bounded devotional products are available under the christian-* capability IDs. Runtime requests do not call third-party scripture providers.

## Capabilities

- [Live Chain State Snapshot](https://macaroonnetwork.com/listings/chain-state-snapshot-v1): Get the current block number and gas price for Base or Polygon mainnet, live, with no caching.
- [Extended Guided Confession Reflection](https://macaroonnetwork.com/listings/christian-confession-guided-v1): Return an extended scripture-grounded examination and repair-oriented reflection. It accepts no confession narrative or identity information and provides no absolution.
