Endor Labs uses conventional gRPC and HTTP response codes to indicate the success or failure of an API request.

<Note>
  When making API requests, always implement proper error handling to gracefully manage these response codes.

## gRPC status codes

<YamlTable>
  {`


    - Value: 0
    Code_Name: OK
    Description: Not an error; returned on success.
    - Value: 1
    Code_Name: CANCELLED
    Description: The caller typically cancelled the operation.
    - Value: 2
    Code_Name: UNKNOWN
    Description: Unknown error; typically indicates an unexpected error.
    - Value: 3
    Code_Name: INVALID_ARGUMENT
    Description: The client specified an invalid argument.
    - Value: 4
    Code_Name: DEADLINE_EXCEEDED
    Description: The deadline expired before the operation could complete.
    - Value: 5
    Code_Name: NOT_FOUND
    Description: The API did not find the requested entity, such as a file or directory.
    - Value: 6
    Code_Name: ALREADY_EXISTS
    Description: The entity that a client attempted to create already exists.
    - Value: 7
    Code_Name: PERMISSION_DENIED
    Description: The caller does not have permission to execute the specified operation.
    - Value: 8
    Code_Name: RESOURCE_EXHAUSTED
    Description: Some resource no longer has capacity, perhaps a per-user quota, or the entire file system is out of space.
    - Value: 9
    Code_Name: FAILED_PRECONDITION
    Description: The system is not in a state required for the operation's execution.
    - Value: 10
    Code_Name: ABORTED
    Description: A concurrency issue like a sequencer check failure typically aborted the operation.
    - Value: 11
    Code_Name: OUT_OF_RANGE
    Description: The client attempted the operation beyond the valid range, such as seeking past the end of a file.
    - Value: 12
    Code_Name: UNIMPLEMENTED
    Description: The operation is not implemented or is not supported or enabled in this service.
    - Value: 13
    Code_Name: INTERNAL
    Description: Internal errors; the underlying system broke invariants it expected to hold.
    - Value: 14
    Code_Name: UNAVAILABLE
    Description: The service is currently unavailable. This is most likely a transient condition; retry with a backoff to recover.
    - Value: 15
    Code_Name: DATA_LOSS
    Description: Unrecoverable data loss or corruption.
    - Value: 16
    Code_Name: UNAUTHENTICATED
    Description: The request does not have valid authentication credentials for the operation.

## HTTP status codes

<YamlTable>
  {`


    - Value: 200
    Code_Name: OK
    Description: Everything worked as expected.
    - Value: 400
    Code_Name: Bad Request
    Description: The request was unacceptable, often due to missing a required parameter.
    - Value: 401
    Code_Name: Unauthorized
    Description: No valid API key provided.
    - Value: 402
    Code_Name: Request Failed
    Description: The parameters were valid but the request failed.
    - Value: 403
    Code_Name: Forbidden
    Description: The API key doesn't have permissions to perform the request.
    - Value: 404
    Code_Name: Not Found
    Description: The requested resource doesn't exist.
    - Value: 409
    Code_Name: Conflict
    Description: The request conflicts with another request, possibly due to using the same key.
    - Value: 429
    Code_Name: Too Many Requests
    Description: You sent too many API requests to Endor Labs in a short time. We recommend using an exponential backoff strategy for your requests.
    - Value: "500, 502, 503, 504"
    Code_Name: Server Errors
    Description: Something went wrong on the Endor Labs side (these are rare).

    `}

<Note>
  When receiving a 429 status code, implement an exponential backoff strategy to avoid overwhelming the API.
