The docs state that the RPC comes with a few defaultRPCs and then links to polkadotJS documentation on the available API calls. This doesn't help me if I want to call a method using curl.

Does anyone know how to call contractInfoOf using curl?

I've tried storage_contract_info_of, storage_contractInfoOf, and various other combinations using contracts as the prefix.

e.g.

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "contracts_contractInfoOf", ["5CYKEXWU3L4zWregopd2bTjoZLH9yHBpfXaqkFaTfxacaSA1"]}' http://substrate-node:9933/

However, none of these seem valid. I've used grep to look for a list of rpc calls in substrate and I got the following:

> grep -rPo '#\[rpc\(name\s=\s"([A-Za-z_]*)' | sort | uniq | awk -F '"' '{print $2}'

No mention of contractInfoOf. Where is it located and how do I call it?

    curl rpc_methods will show you all calls exposed by the node. contractInfoOf is a state call, e.g. the correct storage key to stage_getStorage

  • Is the storage key the encoded contract address? e.g. u8aToHex(decodeAddress("5CYKEXWU3L4zWregopd2bTjoZLH9yHBpfXaqkFaTfxacaSA1"))

    It is encoded using the hasher for the map. One of the examples that show the key I can think of is the apps UI chain-state app, e.g. Canvas on Rococo has contracts, so if you navigate in that app to contracts.contractInfoOf you can see how the key is generated in the details below.

I'm reposting the answer from Jaco above, so that this question no longer shows up as one without answers.
