# List culture line prices

> Each priced culture line's current list and wholesale price and its pricing tier, newest first by when the line was first priced. Filter to one culture line with plant_id, or to one tier with pricing_tier.

`GET https://app.xplantpro.com/api/v1/pricing/culture-lines`

- Required scope: `read:pricing`
- Credentials: workspace API key (`xpk_`)
- Idempotency-Key: ignored on this endpoint

Every amount is exact decimal text with its currency. Never add amounts in different currencies.

Needs culture line pricing in the workspace's plan; without it the answer is `FEATURE_NOT_INCLUDED`.

## Query parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `plant_id` | string (uuid) | No | Only this culture line's price. A culture line is identified by its plant id. |
| `pricing_tier` | string | No | Only culture lines in this pricing tier, spelled exactly as your lab names it. 1–40 characters. |
| `limit` | integer | No | Page size. Values above 200 are capped at 200. Default `50`. From 1 to 200. |
| `offset` | integer | No | Number of records to skip. Prefer `cursor` where a list offers it: an offset shifts when records are added ahead of it. Default `0`. At least 0. |
| `cursor` | string | No | Continue from the previous page: pass its `meta.next_cursor` unchanged, with the same filters. Treat it as opaque. Not combinable with `offset`. Up to 2048 characters. |

## Example

**curl**

```bash
curl "https://app.xplantpro.com/api/v1/pricing/culture-lines?plant_id=0b8e2f4c-6a1d-4c3e-9f7a-2d5b8c1e4a90" \
  -H "Authorization: Bearer $XPLANT_API_KEY"
```

**JavaScript**

```js
import { XPlantClient } from "@shmaplex/xplant-sdk";

const client = new XPlantClient({ apiKey: process.env.XPLANT_API_KEY });

const prices = await client.pricing.listCultureLines({ plant_id: "0b8e2f4c-6a1d-4c3e-9f7a-2d5b8c1e4a90" });
```

**Python**

```python
import os
import requests

resp = requests.get(
    "https://app.xplantpro.com/api/v1/pricing/culture-lines",
    headers={"Authorization": f"Bearer {os.environ['XPLANT_API_KEY']}"},
    params={"plant_id": "0b8e2f4c-6a1d-4c3e-9f7a-2d5b8c1e4a90"},
    timeout=10,
)
body = resp.json()
if not body["ok"]:
    raise RuntimeError(f"{resp.status_code} {body['code']}: {body['error']}")
prices = body["data"]
```

## Response

`200` with `{ "ok": true, "data": … }`. `data` is an array. To get the next page, pass `meta.next_cursor` back as `cursor`; it is `null` on the last page. See [Pagination](https://docs.xplantpro.com/docs/pagination.md).

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string (uuid) | Yes | — |
| `plant_id` | string (uuid) | Yes | The culture line this price is for (a plant id). |
| `list_price` | object | Yes | — |
| `list_price.amount` | string | Yes | An exact decimal, as text — for example `"1250.00"`. Never a floating-point number; parse it with a decimal type. |
| `list_price.currency` | string \| null | Yes | ISO 4217 currency code, for example `USD`. Null only when the record carries no currency. Never add amounts in different currencies. |
| `wholesale_price` | object \| null | Yes | — |
| `previous_list_price` | object \| null | Yes | The list price before the latest change, in the currency it was set in. Null until the price has changed once. |
| `pricing_tier` | string \| null | Yes | The line's pricing tier, as your lab names its tiers. |
| `tier_score` | string \| null | Yes | The score the tier was derived from, as exact decimal text. Not money. |
| `price_source` | string | Yes | Who set the list price: `manual`, `store_adopted`, `store_follow`. `manual` is a person typing it, `store_adopted` a person accepting the price from your store, and `store_follow` an automatic update that follows your store's price. |
| `price_source_at` | string \| null | Yes | When the list price was last set that way, as an ISO 8601 timestamp. |
| `notes` | string \| null | Yes | — |
| `created_at` | string \| null | Yes | When the culture line was first priced. |
| `updated_at` | string \| null | Yes | — |

The envelope can also carry `meta`:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `next_cursor` | string \| null | Yes | Pass as `cursor` to fetch the next page. `null` means this is the last page. |

| Response header | Meaning |
| --- | --- |
| `X-Request-Id` | Identifies this request. Include it when you contact support. |

## Errors

| Status | Code | When |
| --- | --- | --- |
| `401` | `UNAUTHORIZED` | The key is missing, malformed or revoked, or its owner is no longer a member of the workspace. |
| `402` | `PAID_PLAN_REQUIRED` | The workspace's plan does not include the API. The full API is included with xPlant+ Teams and Enterprise; on Hobby and Pro Lab, keys can connect devices only. |
| `402` | `FEATURE_NOT_INCLUDED` | Culture line pricing is not included in your plan. |
| `403` | `FORBIDDEN` | The key lacks a scope this operation requires, or its owner's current role in the workspace cannot use it — a key never does more than its owner can in xPlant. `error` names the scope, and for a role, the role it needs. |
| `403` | `DEVICE_TOKEN_NOT_ACCEPTED` | A device token was sent; this operation needs a workspace API key. |
| `404` | `NOT_FOUND` | `plant_id` names no culture line in the key's workspace. |
| `422` | `VALIDATION_ERROR` | Both `cursor` and `offset` were sent; use one. |
| `422` | `INVALID_CURSOR` | The cursor is malformed, or came from a different list or different filters. Start again without it. |
| `422` | `VALIDATION_ERROR` | A query parameter is malformed. `error` names it. |
| `429` | `RATE_LIMIT_EXCEEDED` | Too many requests for this key, device token or workspace. Wait `Retry-After` seconds. |
| `500` | `FEATURE_CHECK_FAILED` | Your plan could not be checked. Retry later. |
| `500` | `CULTURE_LINE_PRICE_QUERY_FAILED` | The prices could not be read. Retry later. |

Branch on `code`, never on the `error` text. See [Errors](https://docs.xplantpro.com/docs/errors.md).
