Invalid API Key when using claude 2.0

[shirubei]

Windows 11 with Pythno 3.10 and used these codes . It turned out to an "Invalid API Key" error.
But I'm sure the api_key is good because I could get good response via unofficial API call (from other github repository).

from anthropic import Anthropic, HUMAN_PROMPT, AI_PROMPT

anthropic = Anthropic(api_key = "sk-ant-XXXXXX")

def getResponse(prompt):
msg=f"{HUMAN_PROMPT} {prompt} {AI_PROMPT}"
print(msg)
completion = anthropic.completions.create(
model = "claude-2",
max_tokens_to_sample = 30000,
prompt = msg,
)
res = completion.completion
print(res)
return res

if name == "main":
getResponse("Hello, Claude")

the last 3 lines of error messages:
File "D:\Python310\anthropic\lib\site-packages\anthropic_base_client.py", line 761, in _request
raise self._make_status_error_from_response(request, err.response) from None
anthropic.AuthenticationError: Error code: 401 - {'error': {'type': 'authentication_error', 'message': 'Invalid API Key'}}

Appreciate your help. Thanks.

Hmm, that's surprising. Can you share the request ID for one working request and one non-working request?

[shirubei]

Thanks for your reply. I have no idea on how to get request ID. Would you please show me those steps ? @rattrayalex

In this library, it's like this:

from anthropic import Anthropic, HUMAN_PROMPT, AI_PROMPT, APIStatusError

anthropic = Anthropic(api_key="sk-ant-XXXXXX")

def getResponse(prompt):
  msg=f"{HUMAN_PROMPT} {prompt} {AI_PROMPT}"
  print(msg)
  try:
    completion = anthropic.completions.create(
      model="claude-2",
      max_tokens_to_sample=30000,
      prompt=msg,
    )
  except APIStatusError as e:
    print('request-id:', e.response.headers['request-id'])
    raise e
    
  res = completion.completion
  print(res)
  return res

Outside of this library, you can make a request with curl and view the headers with -i, eg:

curl -i --request POST \
     --url https://api.anthropic.com/v1/complete \
     --header 'accept: application/json' \
     --header 'anthropic-version: 2023-06-01' \
     --header 'content-type: application/json' \
     --header 'x-api-key: sk-ant-XXXXXX' \
     --data '
{
  "model": "claude-2",
  "prompt": "\n\nHuman: hello? \n\nAssistant:"
  "max_tokens_to_sample": 30000
}
'

Thanks again.
I run this cmd：
curl -i --request POST --url https://api.anthropic.com/v1/complete --header 'accept: application/json' --header 'anthropic-version: 2023-06-01' --header 'content-type: application/json' --header 'x-api-key: sk-ant-XXXXXXXXXXXXXX' --data '{"model": "claude-2", "prompt": "\n\nHuman: hello? \n\nAssistant:", "max_tokens_to_sample": 30000 }'

and output from this curl cmd :

Output from python code provided by you (same as the top thread). @rattrayalex

[rattrayalex]

I think you may need to quote the URL in your curl request, eg; --url "https://api.anthropic.com/v1/complete"

[shirubei]

Thanks.
curl -i --request POST --url "https://api.anthropic.com/v1/complete" --header 'accept: application/json' --header 'anthropic-version: 2023-06-01' --header 'content-type: application/json' --header 'x-api-key: sk-ant-XXXXXXXXX' --data '{"model": "claude-2", "prompt": "\n\nHuman: hello? \n\nAssistant:", "max_tokens_to_sample": 30000 }'

It looks like you're having some trouble sending a valid curl request. Once you're able to show that you can make a successful curl request (or other request) with the exact same API key and can share a request-id header from that request, we can reopen this issue.

[shirubei]

Just want to make sure if there's any ip restrict on your side.
I run the same cmd on a remote machine and it turned out successfully. @rattrayalex

request-id: 5d91bd3b74ebca7c4b167f1c181525123ef7eeac2b58ea3b1ccdd33ae9516b40

PS：I made a mistake. This one also failed with same error "Invalid API Key".

[rattrayalex]

Got it, thank you. Were you able to try the request from the SDK on the same remote machine?

You can use the ANTHROPIC_API_KEY environment variable (instead of passing an api_key kwarg) to ensure it's the exact same one as you use in the curl request (with --header "x-api-key: $ANTHROPIC_API_KEY", of course).
