Data Platform Overview - Hexel Studio

The Data Platform solves two problems for agents: giving them knowledge to search (product docs, policies, internal wikis) and memory to retain (conversation history, user preferences, past decisions). Without these, every agent invocation starts from zero. It provides searchable knowledge stores, scoped memory, connectors that keep content in sync with external sources, and context bundles that assemble grounded context for a run.

Capabilities

Knowledge Stores

Ingest content and search it semantically.

Memory

Record and recall agent memory across scopes.

Connectors

Sync data from Amazon S3 into knowledge stores.

Documents & Uploads

Upload files for automatic chunking and embedding.

Syncs

Monitor ingestion runs across your environment.

Context Bundles

Assemble grounded context for a task run.

Base URL

All Data Platform requests use the REST API:

https://api.hexelstudio.com/data/v1/...

Authenticate with a Bearer token. See Authentication.

The Data Platform is accessed via the REST API and Console only. The Python and TypeScript SDKs cover Compute, Orchestration, and Tools; Data Platform examples in these docs use curl against the REST API.

Errors

Data Platform endpoints return a consistent JSON error body: { "code": "<error_code>", "message": "<human_message>" }. Permission errors include the required permission in details.

`code`	HTTP	When
`AUTH.REQUIRED`	401	Missing or invalid credentials.
`AUTH.PERMISSION_DENIED`	403	Authenticated but lacking the required `data-platform:*` permission.
`RESOURCE.NOT_FOUND`	404	The store, document, datasource, or memory item doesn’t exist.
`VALIDATION`	400	Invalid parameters (out-of-range chunk size, bad query length, etc.).
—	429	Rate limit exceeded (10,000 requests/hour per organization).

Security

Concern	How it’s handled
Authentication	Every request uses a short-lived Bearer token.
Authorization	Each operation requires a `data-platform:<resource>:<action>` permission (for example, `data-platform:knowledge:write`).
Scoping	Knowledge stores, memory, datasources, and documents are scoped to your organization, workspace, and environment.
Storage	Content and embeddings are stored on platform-managed infrastructure; you don’t provision or manage the underlying stores.

Rate limits

Scope	Limit
Per organization	10,000 requests / hour

Pagination

List endpoints accept page (starting at 1) and page_size (1–100, default 20).

curl "https://api.hexelstudio.com/data/v1/knowledge?page=1&page_size=20" \
  -H "Authorization: Bearer $TOKEN"
