The indexer can be run by setting up a development environment. *** ### Who it's for * Developers — inspect policy structures, schemas, and credential documents during development * Registry operators — monitor activity across a Standard Registry and all associated policies * Technical auditors — trace relationships between documents and verify credential chains * VVBs — locate and review policy records, verification documents, and token activity * Researchers — query across the full history of Guardian's on-chain output *** ### Features * Global search across the entire dataset: policy IDs, schema names, VC content, schema properties, and more * Per-section keyword search with AND logic across Accounts, Methodologies, Documents, and Others * Standard Registry detail pages with full activity summaries linking through to all associated records * Policy detail pages covering activity, schemas, tokens, and roles * Schema pages with a field tree diagram and list of all credentials issued against each schema * VC and VP detail pages with document content, full history, and a relationship map * NFT transaction history and topic content listings * Policy comparison view — inspect structural differences between two policy versions * Priority loading queue — push any document, topic, or policy ahead of the standard sync schedule *** ### Source code The Indexer spans several folders in the Guardian monorepo: Relevant directories include `indexer-frontend/`, `indexer-service/`, `indexer-api-gateway/`, `indexer-common/`, `indexer-interfaces/`, `indexer-worker-service/`, `indexer-web-proxy/`. The `docker-compose-indexer.yml` file in the repository root is the starting point for running the stack locally. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://guardian.hedera.com/docs/develop/explorers/guardian-indexer.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
