Describe the bug

Using foundry on docker.

Trying to get forge clone to retrieve contract source code.

forge clone works OK on ETH mainnet (chain_id=1):
forge clone --no-git --no-commit --etherscan-api-key {api_key} --chain 1 0x3554A54BC0F1f3aDABa5E3a4CcB35E84418bF553

but fails on BSC (chain_id=56):
forge clone --no-git --no-commit --etherscan-api-key {api_key} --chain 56 0x55aBdae5B1b94a203362c49be12550e77D73171e
with
Error: Invalid API Key

curl works OK in both cases, so I know the contracts, the chain_id and the api_key are all good:

ETH mainnet:
curl -d "address=0x3554A54BC0F1f3aDABa5E3a4CcB35E84418bF553" "https://api.etherscan.io/v2/api?chainid=1&module=contract&action=getsourcecode&apikey={apikey}"

BSC:
curl -d "address=0x55aBdae5B1b94a203362c49be12550e77D73171e" "https://api.etherscan.io/v2/api?chainid=56&module=contract&action=getsourcecode&apikey={apikey}"

@alandixon we currently don't support the v2 API (looking to add in #9196) please try using a v1 bsc api key

[grandizzy]

@alandixon please reopen if you still hit the issue with a v1 bsc api key. will close this a dupe of #9196 Thank you!

[alandixon]

Actually, curl doesn't even work on api v1, using bscscan example code, so it looks like a bscscan problem.
I'll probably look at using v2 when #9196 is complete,
and work round it for the time being.
Thanks for your help!
