Each entry includes the latest daily metrics snapshot (`latest_metrics`) when available; for products in `pending_deploy` status the metrics field is `null`. Most dashboards call this once on page load and cache the response for ~60 seconds. ## OpenAPI ````yaml /openapi.yaml get /api/partner/products openapi: 3.0.3 info: title: Barker Yield Engine API version: 1.0.0 description: > Yield-embed API for partners (wallets, payment apps). Authentication: `X-Api-Key` header, self-served from portal.barker.money. Revenue: 100% via on-chain fee split inside the engine contract — calling this API is free. Rate limit: 1000 req/min for production keys (`bk_live_*`), 100 req/min for sandbox keys (`bk_test_*`). Anti-abuse, not usage billing. Two integration modes — same engines, same key, same fee split, different UI surface: - Embed (iframe): drop-in UI hosted at app.barker.money, no contract calls in your code. - Headless API: your UI calls BarkerEngine (ERC-4626) directly with the user's wallet; this API serves metadata, position, fee stats, and webhooks. See https://docs.barker.money/integration-modes for the decision guide. Error responses share `{ success: false, code, message }`.
