Developer Guide

The XNDR Network REST API is a read-only interface over indexed ALX Blocks.

Choose an Interface

	Block Explorer	REST API
Needs	A browser and a complete blockHash or contentHash.	A server-side HTTP client. An operator-issued key is optional.
Returns	The Block's identifiers, source observations, and relationships, navigable by clicking.	JSON from nine read-only GET routes under /api/v1, plus a tenth serving the OpenAPI 3.1 document.
Use for	Manual lookup, inspecting one Block, and following lineage without writing code.	Scripts, services, and any integration that reads indexed Blocks on a schedule.

Start Integrating with XNDR Network

1. Make a First Request. Getting Started sends one curl request for a Block hash.
2. Read the Contract. API Overview defines routes, scope, authentication, rate tiers, and errors.
3. Build a Workflow. Integrate with XNDR Network covers discovery, lineage, and verification; the ALX Block Model explains canonical fields.

For every integration, preserve source scope and response boundaries. For code to adapt, see Reference Implementations.

Developer Access

Anonymous requests need no credentials. An XNDR Network operator issues keys for the higher tier; see Authentication.
