Resty is a high-level HTTP client library for Go designed for consuming REST services. It provides a streamlined interface for executing network requests, managing server-sent event streams, and automatically mapping JSON and XML responses into data structures. The library includes built-in mechanisms for service resilience and traffic management, such as circuit breakers to prevent cascading failures, token-bucket rate limiting, and automated request retries with exponential backoff. It also features client-side load balancing to distribute outgoing traffic across multiple base URLs and requ

Refit based web api client management, but resilient (retry, connectivity, cache, auth, log, priority, etc...)

RestSharp is a .NET HTTP client library designed for interacting with RESTful web services. It provides a high-level request wrapper and a dedicated REST API client to manage endpoints, headers, and query parameters. The library includes a serialization mechanism that automatically converts objects to and from JSON or XML formats for API payloads. It also features a system for managing API credentials and security tokens to ensure authorized access to protected remote resources. The toolkit covers broad capabilities for external web service integration, including generic type-based deseriali

A tool that generates boilerplate code for substrate-based chains (calls, storage access, events, etc) using go-substrate-rpc-client.

Ajuna SDK is a .NET toolchain featuring .NET framework extensions and code generation utilities to build substrate storage services and clients quickly. This toolchain ideally extends Ajuna.NetApi library, which provides raw access to substrate nodes.

Axios is an isomorphic, promise-based HTTP client designed for making asynchronous network requests across different JavaScript execution environments, including the browser and Node.js. It functions as a JSON API client that serializes JavaScript objects into JSON and parses server responses into structured data. The project features a system for managing reusable client instances with shared configurations, such as base URLs and default settings. It includes a mechanism for intercepting outgoing requests and incoming responses globally, allowing data to be transformed before it reaches the

Interact with REST services in an ActiveRecord-like manner

flashheart is built on http-transport to provide everything you need to build HTTP-based services with confidence.

node-fetch is a lightweight HTTP client library that implements the browser-standard Fetch API for Node.js. It provides a promise-based interface for making asynchronous network requests to retrieve or send data from server-side environments. The project specializes in memory-efficient data handling by utilizing request and response streaming. This allows for the incremental processing of large network payloads through native system streams to prevent memory exhaustion. The library covers a broad range of networking capabilities, including the use of custom HTTP agents for DNS and SSL config

This is a non-blocking network client for Java applications that provides asynchronous HTTP request capabilities and bidirectional WebSocket connectivity. It leverages a Netty-based architecture to handle high volumes of network input and output. The library utilizes native transport abstractions such as Epoll, KQueue, and io_uring to reduce system latency. It supports HTTP/2 multiplexing to run multiple concurrent request-response streams over a single connection and provides automatic response body decompression for various formats. Core capabilities cover the management of complex network

Ajuna .NET API Full-featured substrate node API

Substrate RPC client in Go. It provides APIs and types around Polkadot and any Substrate-based chain RPC calls. This client is modeled after polkadot-js/api.

Easy-to-use typesafe REST API client library for .NET Standard 1.1 and .NET Framework 4.5 and higher, which is simple and customisable. Inspired by Refit

Our goal is to create a general purpose library for the Cosmos ecosystem. Through this library, blockchains that use cosmos-sdk, as well as Cosmos hub (Gaia), can create their own API for JavaScript client side.

A python3 wrapper around Cosmos API/RPC brought to you by ChihuahuaChain

This project is a Node.js HTTP reverse proxy middleware designed to route incoming HTTP and WebSocket traffic to target backend services. It functions as a dynamic routing engine and API gateway tool, providing the capability to consolidate multiple backend services behind a single entry point. The middleware features a WebSocket proxy bridge that manages protocol upgrade handshakes to maintain persistent bidirectional communication. It also includes a request and response transformer used to intercept and modify headers, bodies, and URL paths during transit. The system provides broad traffi
