Webapp Struct Attribute API Endpoints

Category: webapp (catalog read) Entity: StructAttribute (structs.struct_attribute) Base URL: ${webappBaseUrl} (default: http://localhost:8080, public guild webapp: http://crew.oh.energy) Last Updated: May 13, 2026

Overview

Per-struct typed attributes — health, ambit, build state, and other scalar properties that vary per struct. Cache rows are deleted when the chain attribute reaches zero — missing rows mean “no value”, not “value of zero”.

Responses use the shared envelope ({ "success": true, "errors": {}, "data": [ ...rows ] }); catalog rows are returned directly in data as a flat array with a fixed page size of 100 — if data.length === 100, request the next page. See protocols/webapp-api-protocol.md.
