  title: API Evangelist enhancements for the WAODAO Agent API
  version: 1.0.0
extends: openapi/waodao-agent-api-openapi.json

  The harvested contract (openapi/waodao-agent-api-openapi.json, OpenAPI 3.1.0) is already strong:
  operationIds, tags, summaries, descriptions, component schemas, response headers and live
  externalValue examples on every 200. This overlay adds only API Evangelist enrichment metadata
  and the gaps we observed live — it never mutates the harvested original. Apply with any
  Overlay 1.0.0 processor against openapi/waodao-agent-api-openapi.json.

      Record the observed response size of the full index snapshot so agent clients can budget for
      it (measured 2026-08-09) and prefer per-day traversal for depth.

        Read this once to map the collection (first_day, latest_day, total_days, items[]), then
        traverse per-day with getArtChainDay rather than re-fetching the index.
