In case the compiler is not supporting the direct import from sources like GitHub it is necessary to replace the import statement with a local import of the API. The API is needed to give access to addresses and the functions needed to interact with the oracle. The API allows you to request data that meets the specified filter criteria, and to group that data by the dimension of your choosing. The Usage API is used by the Cost Analysis tool in the Console. Also see Using the Usage API for more information.

Oraclize Usage Uses Oraclize to get off-chain exchange rates through API queries to cryptocompare. · Self Executing Smart Contract Code Oraclize functions are 

Unlike the predis composer package, its more reliable and fast and can be used in bigger applications. We will install the PHPRedis extension using PECL. For those who do not know, PECL is a repository for PHP Extensions.

Pastebin is a website where you can store text online for a set period of time. Is there any way to only encrypt the api key in a GET oraclize query. 2. Transaction api question for using remote Node such as infura.

Oraclize does the query off-chain Oraclize sends a tx calling your _callback function with the result of the API call So none of the nodes or miners call an external service, Oraclize puts the data on the chain once The first one imports the Oraclize API contract containing methods such as oraclize_getPrice,oraclize_query that we will use to interact with oracle and allows us to implement a __callback method that will be called when oraclize returns result after a successfull request. Oracle API Manager Cloud Service enables developers to create new custom APIs and expose them to internal or external consumers in a secure way to help develop innovative offerings for end users. For more information, see the press release and the announcement blog post , and for Datasheets, Pricing, Demo Videos and more, visit the SOA Cloud In result we end up with a simple contract using the Oraclize service to request Fuelprice (let's consider fuel as equivalent to oil). As you can see, we start by importing the Oraclize API: import "./oraclizeAPI_0.5.sol";. Then, we inherit the usingOraclize contract to access the library methods. As a note, I downvoted due to some incorrect points.

For working examples of how to integrate the Provable API into your own smart-contracts, head on over to the Provable Ethereum Examples repository. Here you'll find various examples that use Provable to feed smart-contracts with data from a variety of external sources. The oraclize-lib enables the use of the Provable engine capabilities also in a non-blockchain context, by providing an abstraction layer which resolves to Provable HTTP API. The oraclize-lib is currently in an experimental stage. Oraclize provides a way to get outside data from any web API onto the blockchain To use it, you’ll use Oraclize’s smart contracts to send a query to Oraclize with your API call. Once they get a Yes. I was using oraclize before. Had been some time and when I tried to run oraclize, I was not getting the callback for the query.

In case the compiler is not supporting the direct import from sources like GitHub it is necessary to replace the import statement with a local import of the API. The API is needed to give access to addresses and the functions needed to interact with the oracle. Getting started with the Oraclize API. For a contract to use the Oraclize service, it needs to inherit the usingOraclize contract. You can find this contract at https://github.com/Oraclize/Ethereum-api. The usingOraclize contract acts as the proxy for the OraclizeI and OraclizeAddrResolverI contracts. Users who have contributed to this file 1347 lines (1209 sloc) 56.7 KB Raw Blame Using Oraclize, we’ll see how your smart contracts can get data from outside the blockchain and execute any API call.

java.text Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages. For further API reference and developer documentation, see Java SE Documentation. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. Oracle Integration (OIC). REST API documentation for Oracle Integration. Also includes JavaScript APIs for Visual Builder.

I have read the Oraclize documentation: https://docs.oraclize.it/#home. and similar topic like: How do oracle services work under the hood. But is still have a question, take this example: I have a simple smart contract that makes a Oraclize call (or an API call) to a data source.

Oraclize API fees, 590.2, $36,202 Includes refunds handled by Oraclize smart contracts.

The TopicShare's Oracle smart contract uses oraclize.it's `oraclize-api` library to retrieve the message text of posts on Twitter via URL. These messages are stored on the Ethereum blockchain within this smart contract and is publicly accessible by any other smart contract.

So I start to do research about making API calls with Solidity over Ethereum network.
