Not an incremental feed: re-read the snapshot instead of tracking changes. Ordered by `asset_id`. ## OpenAPI ````yaml api-reference/beta/openapi.json get /public/beta/{env_id}/asset-health-scores openapi: 3.1.0 info: description: > The Elementary Public API is a REST interface for programmatically reading Elementary's assets, columns, lineage, tests, and test results for one environment. **Authentication.** Send a bearer token (personal or account token) in the `Authorization` header. The token resolves to an account; results are scoped to the environments that token may view. **Environment scope.** Every resource lives under `/{env_id}`. Call `GET /environments` first to discover the ids you can access. **Pagination.** List endpoints are keyset-paginated: pass `limit` (default 500, max 2000) and follow `next_cursor` until `has_more` is `false`. Cursors are opaque and bound to the filters that produced them — reusing a cursor with different filters returns `400`. **Incremental sync.** Every dataset supports a full scan (default). Assets, columns, and tests also expose two incremental feeds: `synced_since` (upserts) and `deleted_since` (soft-delete tombstones). A test's `synced_at` tracks its definition — new executions do not bump it. Latest test executions and per-test execution history are **not** incremental. Latest executions are a full snapshot replaced in place: re-read it. Execution history is append-only and scoped to one test, filtered by `start_time_from` / `start_time_to` (last 30 days by default). **Lookback limit.** Explicit lower bounds (`synced_since`, `deleted_since`, `start_time_from`) reach back at most 90 days; an older timestamp is treated as 90 days ago rather than rejected. Omitting the filter still returns the full current snapshot. **Rate limiting.** Requests are rate-limited per account; responses carry `RateLimit-*` headers and `429` responses include `Retry-After`. _Beta: the shape may change while we co-design with early adopters._ title: Elementary Public API version: beta servers: - url: https://prod.api.elementary-data.com security: - bearerAuth: [] tags: - description: Discover accessible environments. name: Environments - description: Lineage assets — tables, views, BI assets. name: Assets - description: Columns of assets. name: Columns - description: Asset-to-asset lineage edges. name: Asset lineage - description: Column-level lineage edges. name: Column lineage - description: Test definitions and their configuration. name: Tests - description: Most recent execution of every sub-test. name: Latest test executions - description: Execution history of a single test. name: Test executions - description: Current data health score per asset. name: Asset health scores paths: /public/beta/{env_id}/asset-health-scores: get: tags: - Asset health scores summary: List asset health scores description: >- Lists the current health score of every asset that has test results in the last 7 days — a full snapshot, recomputed hourly.
