Returns 404 if it doesn't exist in this environment. ## OpenAPI ````yaml api-reference/beta/openapi.json get /public/beta/{env_id}/assets/{asset_id} openapi: 3.1.0 info: description: > The Elementary Public API is a REST interface for programmatically reading Elementary's assets, columns, and lineage 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 and columns also expose two incremental feeds: `synced_since` (upserts) and `deleted_since` (soft-delete tombstones). **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 paths: /public/beta/{env_id}/assets/{asset_id}: get: tags: - Assets summary: Get an asset description: >- Fetches a single asset (common fields) by id.
