Koios Java Client

Last update: Dec 4, 2022

Overview

Koios Java Client

What is Koios?

Koios Java Client Library is based on Koios Elastic Query Layer for Cardano Node by Cardano Community Guild Operators.
Koios is best described as a Decentralized and Elastic RESTful query layer for exploring data on Cardano blockchain to consume within applications/wallets/explorers/etc.
Resource and maintenance requirements for Cardano blockchain components (e.g. cardano-node, cardano-db-sync) are ever-growing. Along with that, every builder needs to identify how to query complex information from the chain.

Overview

Koios Java Client is a Java REST Client library which allows interacting with Koios Server Instances using Java Objects.

Use as a library in a Java Project

Add dependency

For Maven, add the following dependency to project's pom.xml


    io.github.cardano-community
    koios-java-client
    1.9

For Gradle, add the following dependency to build.gradle

compile group: 'io.github.cardano-community', name: 'koios-java-client', version: '1.9'

Get Koios Backend Service

Mainnet

BackendService backendService = BackendFactory.getKoiosMainnetService();

Testnet

BackendService backendService = BackendFactory.getKoiosTestnetService();

Guildnet

BackendService backendService = BackendFactory.getKoiosGuildService();

Get Koios Backend Services

NetworkService networkService = backendService.getNetworkService();
EpochService epochService = backendService.getEpochService();
BlockService blockService = backendService.getBlockService();
TransactionsService transactionsService = backendService.getTransactionsService();
AddressService addressService = backendService.getAddressService();
AccountService accountService = backendService.getAccountService();
AssetService assetService = backendService.getAssetService();
PoolService poolService = backendService.getPoolService();
ScriptService scriptService = backendService.getScriptService();

Advanced Query Example (Testnet)

Querying a Descending Order of All Address Transactions since Block No. #3168087 to Block No. #3168097 (inclusive), Limited to Maximum of 10 Results.

> transactionsResult = addressService.getAddressTransactions(List.of(address), options);">

String address = "addr_test1qzx9hu8j4ah3auytk0mwcupd69hpc52t0cw39a65ndrah86djs784u92a3m5w475w3w35tyd6v3qumkze80j8a6h5tuqq5xe8y";

Options options = Options.builder()
        .option(Limit.of(10))
        .option(Offset.of(0))
        .option(Order.by("block_height", SortType.DESC))
        .option(Filter.of("block_height", FilterType.GTE, "3168087"))
        .option(Filter.of("block_height", FilterType.LTE, "3168097")).build();

Result> transactionsResult = addressService.getAddressTransactions(List.of(address), options);

Toggle Logging By Environment Variable

Would like to query the data with pool name or ticker not just pool ID.

Is your feature request related to a problem? Please describe. Request

Describe the solution you'd like A clear and concise description of what you want to happen.

Describe alternatives you've considered I am not a Dev, trying to learn it.

Additional context

"Hello, thank you for your API. I am seeking support for the following API call:

curl -X POST "https://api.koios.rest/api/v0/pool_metadata" -H "Accept: application/json" -H "Content-Type: application/json" -d '{"_pool_bech32_ids":["pool100wj94uzf54vup2hdzk0afng4dhjaqggt7j434mtgm8v2gfvfgp"]}'

I need to know the pool bech32 ID in order to make the above curl request. Is it possible to use the pool name or ticker instead of the pool ID?"

THANK YOU.

NullPointerException when KOIOS http endpoint is not available

What operating system are you using, and which version?

[ ] Linux / Ubuntu

Steps to Reproduce

Using the latest version of the koios-java-client 1.15.1 I saw some NPE in my bot logs when the koios (mainnet) endpoint is not available

Here's the stack trace

Bump logging-interceptor from 3.14.9 to 4.9.3

Bumps logging-interceptor from 3.14.9 to 4.9.3.

Changelog

Sourced from logging-interceptor's changelog.

Version 4.9.3

2021-11-21

Fix: Don't fail HTTP/2 responses if they complete before a RST_STREAM is sent.

Version 4.9.2

2021-09-30

Fix: Don't include potentially-sensitive header values in Headers.toString() or exceptions. This applies to Authorization, Cookie, Proxy-Authorization, and Set-Cookie headers.

Fix: Don't crash with an InaccessibleObjectException when running on JDK17+ with strong encapsulation enabled.

Fix: Strictly verify hostnames used with OkHttp's HostnameVerifier. Programs that make direct manual calls to HostnameVerifier could be defeated if the hostnames they pass in are not strictly ASCII. This issue is tracked as [CVE-2021-0341].

Version 5.0.0-alpha.2

2021-01-30

In this release MockWebServer has a new Maven coordinate and package name. A longstanding problem with MockWebServer has been its API dependency on JUnit 4. We've reorganized things to remove that dependency while preserving backwards compatibility.

Maven Coordinate Package Name Description

com.squareup.okhttp3:mockwebserver3:5.0.0-alpha.2 mockwebserver3 Core module. No JUnit dependency!

com.squareup.okhttp3:mockwebserver3-junit4:5.0.0-alpha.2 mockwebserver3.junit4 Optional JUnit 4 integration.

com.squareup.okhttp3:mockwebserver3-junit5:5.0.0-alpha.2 mockwebserver3.junit5 Optional JUnit 5 integration.

com.squareup.okhttp3:mockwebserver:5.0.0-alpha.2 okhttp3.mockwebserver Obsolete. Depends on JUnit 4.

The new APIs use mockwebserver3 in both the Maven coordinate and package name. This new API is not stable and will likely change before the final 5.0.0 release.

If you have code that subclasses okhttp3.mockwebserver.QueueDispatcher, this update is not source or binary compatible. Migrating to the new mockwebserver3 package will fix this problem.

New: DNS over HTTPS is now a stable feature of OkHttp. We introduced this as an experimental module in 2018. We are confident in its stable API and solid implementation.

Fix: Work around a crash in Android 10 and 11 that may be triggered when two threads concurrently close an SSL socket. This would have appeared in crash logs as NullPointerException: bio == null.

Fix: Use plus + instead of %20 to encode space characters in FormBody. This was a longstanding bug in OkHttp. The fix makes OkHttp consistent with major web browsers.

Fix: Don't crash if Conscrypt returns a null version.

Fix: Include the public suffix data as a resource in GraalVM native images.

Maven Coordinate	Package Name	Description
com.squareup.okhttp3:mockwebserver3:5.0.0-alpha.2	mockwebserver3	Core module. No JUnit dependency!
com.squareup.okhttp3:mockwebserver3-junit4:5.0.0-alpha.2	mockwebserver3.junit4	Optional JUnit 4 integration.
com.squareup.okhttp3:mockwebserver3-junit5:5.0.0-alpha.2	mockwebserver3.junit5	Optional JUnit 5 integration.
com.squareup.okhttp3:mockwebserver:5.0.0-alpha.2	okhttp3.mockwebserver	Obsolete. Depends on JUnit 4.

New Endpoints

getPoolDelegatorsHistory - Provides historical record for pool's delegators

getPoolStakeSnapshot - Provides mark, set, and go snapshot values for the pool being queried.

AddressUtxo - Add InlineDatum and ReferenceScript to output

AddressInfo - Additional field address returned in output

AddressAsset - Now returns address and a list of assets

getAccountAddresses - Accepts addressList list and outputs stakeAddress and list of addresses

getAccountAssets - Accepts addressList list and outputs stakeAddress and list of assets
