# Tools Chainhook Documentation

## Pages

- [Chainhook](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook.md): Chainhook is a reorg-aware indexer that serves reliable blockchain data for Bitcoin and Stacks.

#### (chainhook cli)

- [Service deployment](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(chainhook-cli)/service-mode.md): Deploy Chainhook for real-time blockchain event streaming.

#### (event handling)

- [Build a custom indexer](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(event-handling)/custom-indexer.md): Create your own blockchain indexer with Chainhook.

- [Payload handling](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(event-handling)/payload-handling.md): Process and handle Chainhook webhook payloads.
- [Webhook setup](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(event-handling)/webhook-setup.md): Configure webhook endpoints to receive blockchain events.

#### (integrations)

- [Deployment](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(integrations)/deployment.md): Deploy Chainhook in production environments.
- [Node integration](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(integrations)/node-integration.md): Configure Chainhook with Bitcoin and Stacks nodes.

#### (overview)

- [Concepts](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(overview)/concepts.md): Chainhook's power comes from its predicate-based architecture and automatic handling of blockchain reorganizations. Understanding these concepts helps you build reliable blockchain indexers.
- [Scanning for events](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/(overview)/quickstart.md): Create your first Chainhook predicate to scan blockchain events.

#### Examples

- [Observing contract calls with Chainhook](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/examples/observing-contract-calls.md): Learn how to use Chainhook to observe a function call for a voting contract.
- [Register Chainhooks on devnet](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/examples/register-chainhooks-on-devnet.md): Learn how to register chainhooks on devnet.
- [Run Chainhook as a service](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/examples/chainhook-as-a-service.md): Learn how to run Chainhook as a service to evaluate your "if this, then that" predicates against the Bitcoin and Stacks blockchains.
- [Run Chainhook as a service with a Stacks node](https://hiro-systems-docs-git-develop-hirosystems.vercel.app/tools/chainhook/examples/chainhook-as-a-service-with-stacks-node.md): Learn how to run Chainhook as a service with a Stacks node to evaluate Stacks blocks against your predicates.
