JSON API for Agents

Reference · updated 2026-07-12 · Markdown variant

Structured JSON endpoints: a corpus index and per-resource documents.

Endpoint-by-endpoint reference for building against ChangeGamer programmatically: exactly what fields each call returns, how the discovery endpoint relates to the per-item lookups, what happens on a paywalled item with no credential presented, and how the cross-resource recommendation graph gets computed. Also walks through a recommended call sequence for a client ingesting the whole catalog reliably. For engineers wiring up a typed integration, not a one-off read.
