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?
@Hedge-Fx the callback is the entrypoint so if you want to do anything with the result you can postprocess it within callback and then call your own minter function straight from there, there are plenty of examples in our official doc at docs.provable.xyz or on github in the ethereum-examples repo of the provable-things org
function update() public payable
{
emit LogNewProvableQuery("Provable query was sent, standing by for the answer...");
currentID = provable_query("URL", 'html(https://www.youtube.com/watch?v=9bZkp7q19f0).xpath(//*[contains(@class, "watch-view-count")]/text())');
}currentID parameter to store the query id, the rest is the same as the sample code in YoutubeViews.sol
@nhatminh12369 - unfortunately that sample code is deprecated (we will mark as deprecated soon, since there are a lot of users reporting the same issue) because the youtube html page retrieved by our engine misses the html element containing the number of views.
You can check that yourself running this command
`curl https://www.youtube.com/watch?v=9bZkp7q19f0` -o youtube.html
and check the content of the youtube.html\ page.
We suggest you to run the test above before running the query in order to be 100% sure that the html element you're looking for exists inside the page.
@oraclize-support it worked for me now when I try with my own API. However, it took 1h20 mins for the callback to be called on Kovan and that's very long (https://kovan.etherscan.io/address/0xCB511504a4Dd627a395d043a9C41a23A1CB47706). I tried ChainLink before and it usually took around 1-2 minutes to receive the callback call. Why does Provable take so long to make the callback call? Is it the same on other test nets and main net?
unfortunately that sample code is deprecated
btw, thanks for letting me know, I didn't notice that an html element was missing
@oraclize-support your service down or?
@coiny123 - yes, you can use the
ethereum-bridge for that: https://github.com/provable-things/ethereum-bridge
Hope this isn't a feature of main net
@0x1hack - we're not integrated there but you can use the
ethereum-bridge if you want to on bsc: https://github.com/provable-things/ethereum-bridge
