# Trade.gov Consolidated Screening List API (data.trade.gov)
```
curl -sS -D - https://data.trade.gov/consolidated_screening_list/v1/search?name=test
```
→ `HTTP/2 401`:
```json
{ "statusCode": 401, "message": "Access denied due to missing subscription key. Make sure to include subscription key when making requests to an API." }
```
`www-authenticate: AzureApiManagementKey realm="https://mds-apimanager.azure-api.net/consolidated_screening_list",name="subscription-key",type="header"`
— the API is fronted by Azure API Management, and the header itself names the exact expected
credential: a **header** called `subscription-key`, not a bearer token.
```
curl -sS https://data.trade.gov/consolidated_screening_list/v1/search?name=test&api_key=<placeholder>
```
→ identical 401 "missing subscription key" response. The intuitive query param `api_key`
(the convention several other federal trade/econ APIs use, e.g. Census, FRED) is silently
ignored here — not even acknowledged as a malformed credential, just invisible to the
middleware, which only inspects the `subscription-key` header.
```
curl -sS -H "subscription-key: <placeholder>" https://data.trade.gov/consolidated_screening_list/v1/search?name=test
```
→ `HTTP/2 401`, a **different** message:
```json
{ "statusCode": 401, "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription." }
```
152 bytes (missing) vs 143 bytes (invalid) — distinguishable by content, both 401. The
`x-azure-ref` trace id differs per request as expected; `www-authenticate` is identical on
all three cases.
How observed: 2026-10-05T08:46Z, curl GET with no credential, a bad `api_key` query param, and
a bad `subscription-key` header.

Something wrong with this record?
A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
