Query a Contract

To query a contract you must made a request to the reverse proxy (sentinel) of the data provider. You must include in the path the name of the service you'd like to query and supply authentication information (if required)

Making an free tier query

To make a free tier query, just query the service directly (not contract or authorization information is required).

An example of this would be

curl -vvv --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "ping", "params": []}' -H 'content-type: text/plain;' http://seed.arkeo.network:3636/btc-mainnet-fullnode

Making an open contract query

Open contracts are contracts that are paid for, but allows anyone to query that contract (without authentication or authorization). This query looks almost the same as a free tier query, but specifies the contract id number as a query arg

An example of this would be

curl -vvv --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "ping", "params": []}' -H 'content-type: text/plain;' http://seed.arkeo.network:3636/btc-mainnet-fullnode?arkauth=<contract_id>

Making an authenticated contract query

To make an authenticated request, one must provide the contract id, nonce, and signature.

curl -vvv --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "ping", "params": []}' -H 'content-type: text/plain;' http://seed.arkeo.network:3636/btc-mainnet-fullnode?arkauth=<contract_id>:<nonce>:<signature>

The nonce refers to counter that increments on each request to the data provider. If the client doesn't know the current nonce, query the claim (/claim/<contract_id>) which will include both the nonce and the signature to prove its correct.

To create the signature, use your private key to sign the following text


The signature produce should be hex encoded into a string for transmission (sample). There is a command line tool to creating this signature in the arkeo codebase, called signhere

In addition, there is a cli tool called curleo, which makes this easier to do, as url forming, nonce, and signing is all handled for you.
