Pricing API

WARNING

The order-service pricing endpoints (/api/data/v0/order/price and /api/data/v0/order/price/batch) are deprecated. Use the DPAP service endpoints instead:

GET https://app.open-cosmos.com/api/data/v1/dpap/policies/{policy_id}/catalog/price
POST https://app.open-cosmos.com/api/data/v1/dpap/policies/{policy_id}/catalog/price/batch

The deprecated endpoints still work but will be removed in a future release.

Before placing an order you can retrieve the price for one or more catalogue items. Prices are contract-specific — the rate per km², currency, and any applicable discounts are all determined by your contract terms. This is why a contract_id (used as the policy_id in the DPAP endpoints) is required on every pricing request.

There are two ways to get pricing information:

Dedicated pricing endpoints (this page) — call the DPAP /catalog/price or /catalog/price/batch endpoints directly with a policy_id.
Inline with STAC search — pass contract_id (or project) as a query parameter on any STAC search or item request and prices will be embedded directly in the returned items as opencosmos:price and opencosmos:price_currency properties. See A Note on Pricing for details.

Both approaches return the same contract-specific prices.

NOTE

All endpoints require a valid bearer token. See the Authentication page for details.

Get Price for a Single Item

Returns the computed price for a single catalogue item.

Endpoint

GET https://app.open-cosmos.com/api/data/v0/order/price

Query Parameters

Parameter	Type	Required	Description
`collection`	string	Yes	The STAC collection ID.
`item`	string	Yes	The STAC item ID.
`contract_id`	integer	Yes	The contract ID under which the purchase is made. See how to retrieve your contract ID.
`satellite`	string	No	Satellite name (e.g. `Sentinel-2A`). Avoids an extra STAC lookup when provided.
`level`	string	No	Processing level (e.g. `L2A`). Avoids an extra STAC lookup when provided.
`area`	number	No	Area in km². Avoids an extra STAC lookup when provided.
`origin`	string	No	Origin identifier passed through to the pricing engine.

NOTE

The satellite, level, and area parameters are all optional optimisations. When provided together they allow the service to skip a STAC item lookup, reducing latency. If any of the three is missing the service fetches the details from STAC automatically.

Python

import requests

# Get bearer token and add to session (see Authentication docs)

response = session.get(
    "https://app.open-cosmos.com/api/data/v0/order/price",
    params={
        "collection": "sentinel-2-l2a",
        "item": "S2A_MSIL2A_20230615T100559_N0509_R022_T33UUP_20230615T135959",

Get Prices for Multiple Items

Calculates prices for a batch of catalogue items in a single request.

Endpoint

POST https://app.open-cosmos.com/api/data/v0/order/price/batch

Query Parameters

Parameter	Type	Required	Description
`contract_id`	integer	Yes	The contract ID under which the purchases are made. See how to retrieve your contract ID.
`origin`	string	No	Origin identifier passed through to the pricing engine.

Request Body

An array of item objects. Each object identifies the STAC item and optionally carries pre-fetched STAC item details to avoid additional lookups.

Field	Type	Required	Description
`collection`	string	Yes	The STAC collection ID.
`item`	string	Yes	The STAC item ID.
`satellite`	string	No	Satellite name. Avoids an extra STAC lookup when provided with `level` and `area`.
`level`	string	No	Processing level.
`area`	number	No	Area in km².
`project_id`	string	No	Project ID to associate with the item.

Response

An array of price objects, one per input item, in the same order as the request.
