so...is provable depreciated beyond reasonable use? Looks like the testnet is down, and I can't find any examples that will compile. Even the 0.4.22 versions on docs.provable.com fail as the import line to "github.com/provable-things/ethereum-api/provableAPI_0.4.25.sol"; no longer works...
@gwills:[matrix.org](http://matrix.org) probably remix doesn't support github sym link anymore. Try to replace the import string with the following one:
import "github.com/provable-things/ethereum-api/provableAPI_0.5.sol";
This should compile fine
@oraclize-support I am not sure if it is working. https://kovan.etherscan.io/address/0x8ebca32bd42d86ee51f762e968667e40b612b6f1
No callback called for the last 7 days.
where can I see if your Smart Contracts execute callbacks ?
It would make things much easier if I can see if there was some issue in my function or you just don't call the callback. I thought this address is somethign I can use: https://kovan.etherscan.io/address/0x8ebca32bd42d86ee51f762e968667e40b612b6f1 Because this is the SC which executes callback. I think...
@oraclize-support the query I mentioned in my comment above should've executed about 20 minutes ago, but that hasn't happened. Can you guys please give me some assistance with this? We're talking about 0.3 ETH here so it's not a huge amount of money but it would be GREAT if there was some way to recover it.
That's the transaction where the query was created. If there's a way for you guys to force query execution to return a particular result, PLEASE let me know before doing it!
@nicolas-siplis we cannot forge any result unless this is what your contract queries asked for. If you are missing a mainnet result we need to dive deeper to see ifthe error was in your or our end. We’ll look into it and let you know. Feel free to send us an email to info@provable.xyz too, thanks
@nicolas-siplis the calback was just sent. It wasn't sent as you haven't specified any gasprice so the default free one of 20 gwei got used, which is insufficient to get the tx accepted by nodes as the baseprice is currently much higher than that. We have sent it back to your contract with 120 gwei of gasprice paying out the gas for that tx put of our pocket, for the future please select the correct gasprice when sending the query (as recommended by the documentation). Callback tx: https://etherscan.io/tx/0x90034ade4512ac63a7cc201e68011c9a766e0d3a2252103f0f94460ea5e7227d
Hello. Does anyone have a working remix example of getting site data using xpath? I am trying to reproduce https://github.com/provable-things/ethereum-examples/blob/master/solidity/YoutubeViews.sol and deploy to Kovan testnet. It's running without errors but, I can't wait results, they are blank, it's seems __callback does not event start. (I slightly changed xpath to a new manner but it still not works)
Hi @NazarovALAL, unfortunately YouTube doesn't provide the same HTML code you see when accessing the page through your browser, hence why the xpath clause fails to get the views. This happened to other users before and the code there is a bit out of date for that purpose but still valid as an example if you want to access an HTML through .xpath().
You can do a test by looking for an website where you get the same HTML by other means other than the browser (using curl or wget for example)
@oraclize-support Hi, ty for answer, as I said I changed xpath for new version of youtube. Actually example with "provable_query("WolframAlpha", "temperature in London");" was working yesterday, but today, like in the example with YouTube I can't wait response, maybe temporary problems
Yeah tried that but 0.001 ETH is too low for my needs. Found https://app.mycrypto.com/faucet which gives 0.01 3 times, which is just enough!
I know you can use XPath for XML as well as HTML, but I'm wondering how Provable's simplified XML-specific path specification works
Hi @nicolas-siplis, thanks for your question. As XML-specific we are using the
xmltodict python module, you can have more details here: https://pypi.org/project/xmltodict
@Hedge-FX have you tried importing the latest version? It should work fine with little to no changes: https://github.com/provable-things/ethereum-api/blob/master/provableAPI_0.6.sol

I have the same issue, I can't see the __callback Txn by using Rinkeby Testnet
Hey @oraclize-support , btw, here is my query id on
Kovan 0x1d241954e00599797de78a4030297f9e4c45b77a4f018e2ee68d748bb104017c, just in case u need it for investigation. I also try the https://app.provable.xyz/home/check_query but it unable to find my query. I am not sure if that tool only check for query on the main net?
