# 30MHz

> 30MHz is a Rotterdam-based horticulture technology company. It builds wireless in-crop sensors and
> the ZENSIE data platform for greenhouse and controlled-environment growers, and exposes a public
> REST API — the ZENSIE API — for reading sensor data, pushing external data in, and managing the
> platform. This file was GENERATED by API Evangelist from 30MHz's own published surface on
> 2026-09-05. 30MHz does not publish an llms.txt; /llms.txt returns 404 on 30mhz.com, api.30mhz.com
> and support.30mhz.com.

## API

- [ZENSIE API base](https://api.30mhz.com/api): REST, Swagger 2.0, 425 paths and 558 operations.
- [Swagger contract](https://api.30mhz.com/api/swagger.json): the machine-readable definition, served
  by the API host itself. The Swagger UI is at https://api.30mhz.com/api/swagger.
- Authentication: a bearer JWT API key in the `Authorization` header. Create it in the ZENSIE web app
  under Account Settings > Developer > Request new API key. No OAuth, no scopes.

## Core concepts

- **check** — a data source. Every sensor channel, imported feed or manual input sheet is a check,
  addressed by `checkId`. `checkId` is the primary key of the whole data surface; it appears in the
  ZENSIE URL when a data source is selected.
- **organization** — the tenant. Most reads are scoped by `organizationId`.
- **site / location** — a physical growing site. `location` is the legacy vocabulary and is deprecated
  in the contract; `site` is the live one.
- **zone** — a subdivision of a site, used for maps.
- **sensor type** — the measurement schema a check reports against.
- **import check** — an externally-fed check, populated through the ingest surface.
- **cultivation** — a crop cycle, with targets.

## Key operations

- `getDataForSensors` — POST /data/sensors — the main read: measurements for a set of checkIds.
- `getOrganizationChecks` — GET /check/organization/{organizationId} — find every checkId you own.
- `getCheckLastRecordedState` — GET /stats/check/{checkId} — latest value for one check.
- `getCheckStatsByTimeInterval` — GET /stats/check/{checkId}/from/{startDate}/until/{endDate}
- `getChecksStatsByTimeInterval` — POST /stats/from/{startDate}/until/{endDate} — many checks at once.
- `getNetworkStatusOverview` — GET /stats/network/organization/{organizationId}
- `ingestImportChecks` — POST /ingest/organization/{organizationId} — push data in, max 100 events per
  call (HTTP 413 beyond that).
- `createDataExport` — POST /data-export — schedule a bulk export.

## What 30MHz does NOT publish

Recorded so an agent does not go looking. Every one of these was probed on 2026-09-05.

- No OpenAPI 3.x. The contract is Swagger 2.0.
- No MCP server, no agent card, no A2A surface.
- No AsyncAPI and no advertised webhooks. The only outbound mechanism is a scheduled export-partner
  push to a URL you register.
- No `/.well-known/` documents of any kind on any host, and no security.txt.
- No published rate limits, no `RateLimit-*` headers, no documented 429.
- No idempotency key on any of the 240 mutating operations.
- No RFC 9457 problem+json. Errors are `{"message": "..."}`.
- No public SDK on npm, PyPI, RubyGems or crates.io. A first-party Python client exists but is only
  available on request through support.
- No CLI, no public Postman collection, no sandbox or test mode.
- No status page, no SLA, no deprecation policy — even though 19 operations are marked deprecated.
- No public API changelog. The support centre's "What's new" is an undated product changelog.
