API accepting requests with new keys?

[dacut]

Hello there,

I just applied for and received an API key for api.gsa.gov, but I'm not seeing the expected responses.

GET https://api.gsa.gov/acquisition/cap/v1/documents responds with a 403 Forbidden:

  {"type":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html#sec10.4.4","title":"You do not have access to this resource.","status":403,"detail":"Forbidden."}

GET https://api.gsa.gov/acquisition/cap/v1/search/documents/Test1 responds with a 500 Internal Server Error, showing what looks like an ElasticSearch/OpenSearch error:

  {"type":"http:\/\/www.w3.org\/Protocols\/rfc2616\/rfc2616-sec10.html#sec10.5.1","title":"Search API Exception: Unknown index with ID document_library..","status":500,"detail":"Server configuration error."}

Here's what the request/response (sanitized, omitting API key, cookies) looks like:
gsa-api-list-documents.txt

Thanks!
