# Get JSON Web Key Set

Gets a JSON object that represents a set of JWKs. The JSON object MUST have a keys member, which is an array of JWKs.

Endpoint: GET /projects/{project_id}/jwks.json
Version: v1

## Path parameters:

  - `project_id` (string, required)
    Login project ID from Publisher Account.

## Response 200 fields (application/json):

  - `keys` (array)
    The value of the 'keys' parameter is an array of JWK values.  By default, the order of the JWK values within the array does not imply an order of preference among them, although applications of JWK Sets can choose to assign a meaning to the order for their purposes, if desired.
    Example: [{"alg":"RS256","e":"10001","kid":"NjVBRjY5MDlCMUIwNzU4RTA2QzZFMDQ4QzQ2MDAyQjVDNjk1RTM2Qg","kty":"RSA","n":"yeNlzlub94YgerT030codqEztjfU_S6X4DbDA_iVKkjAWtYfPHDzz_sPCT1Axz6isZdf3lHpq_gYX4Sz-cbe4rjmigxUxr-FgKHQy3HeCdK6hNq9ASQvMK9LBOpXDNn7mei6RZWom4wo3CMvvsY1w8tjtfLb-yQwJPltHxShZq5-ihC9irpLI9xEBTgG12q5lGIFPhTl_7inA1PFK97LuSLnTJzW0bj096v_TMDg7pOWm_zHtF53qbVsI0e3v5nmdKXdFf9BjIARRfVrbxVxiZHjU6zL6jY5QJdh1QCmENoejj_ytspMmGW7yMRxzUqgxcAqOBpVm0b-_mW3HoBdjQ","use":"sig"}]

  - `keys.alg` (string, required)
    The specific cryptographic algorithm used with the key.
    Example: "RS256"

  - `keys.e` (string)
    The exponent for the RSA public key. The value is encoded according to the Base64 standard.
    Example: "AQAB"

  - `keys.kid` (string, required)
    The unique identifier for the key.
    Example: "e600c72b-125a-4b30-86a5-9697af62f2a1"

  - `keys.kty` (string, required)
    The family of cryptographic algorithms used with the key.
    Example: "RSA"

  - `keys.n` (string)
    The modulus for the RSA public key. The value is encoded according to the Base64 standard.
    Example: "eWVObHpsdWI5NFlnZXJUMDMwY29kcUV6dGpmVV9TNlg0RGJEQV9pVktrakFXdFlmUEhEenpfc1BDVDFBeHo2aXNaZGYzbEhwcV9nWVg0U3o="

  - `keys.use` (string, required)
    How the key was meant to be used; sig represents the signature, enc represents the encryption.
    Example: "sig"

  - `keys.x5c` (array)
    The x.509 certificate chain. The first entry in the array is the certificate to use for token verification; the other certificates can be used to verify this first certificate.

  - `keys.x5t` (string)
    The thumbprint of the x.509 cert (SHA-1 thumbprint).
    Example: "NjU3NDI5ZTZhODU0YjQzMGFiYzkwNGNkZDkwNmZkMzZmOWEzNWVmMQ"

## Response 400 fields (application/json):

  - `error` (object, required)

  - `error.code` (string, required)
    Error code.
    Example: "003-061"

  - `error.description` (string, required)
    Error description.
    Example: "Object not found."

  - `error.details` (object)
    Additional information.

## Response 404 fields (application/json):

  - `error` (object, required)

  - `error.code` (string, required)
    Error code.
    Example: "003-061"

  - `error.description` (string, required)
    Error description.
    Example: "Object not found."

  - `error.details` (object)
    Additional information.
