JSON
JSON
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.Starting Price: Free -

Welcome and thanks for using Newsletter2Go. Our REST API exchanges data in the JSON data format. Every parameter/payload you pass (with very few exceptions, e.g., when you upload files) should therefore be formatted in JSON and our API will always return results in JSON as well. Our API follows a very RESTful approach. Most importantly, we support the four standard request methods for CRUD operations. A transactional mailing is a type of mailing that is highly customized, sent to a single individual at a custom time mostly through the system and triggered by an API call. One, if not the most important purpose, of using the Newsletter2Go API is to send transactional emails. Over the last couple of years we have optimized this process in order to offer this very powerful feature to single developers as well as professional teams. First, you will have to create a new mailing. -

ManyPI supports scalable extraction tasks, global infrastructure for performance and uptime, and integration into existing apps or pipelines via code or dashboard, and it also provides visual schema building and connectors for no-code platforms like Zapier and Make, so workflows can automate data collection, enrichment, and reporting without heavy engineering.Starting Price: $5 per month -

Telize
Telize
Telize is a REST API built in C with Kore allowing to get a visitor IP address and to query location information from any IP address. It outputs JSON-encoded IP geolocation data, and supports both JSON and JSONP. Geolocation operations are performed using libmaxminddb which caches the database in RAM. Therefore, Telize has very minimal overhead and should be blazing fast. The default Telize configuration does not have logging enabled, it must be configured manually. There are commented out accesslog directives in conf/telize.conf for each domain block. If your Telize instance produces lots of logs, Logswan might be of interest. Since version 3.0.0, Telize now dynamically calculates timezone offsets (UTC time offset) and adds data to the payload. -

Etheno
Crytic
Etheno is an Ethereum-testing, JSON RPC multiplexer, analysis tool wrapper, and test integration tool. It eliminates the complexity of setting up analysis tools like Echidna on large, multi-contract projects. If you are a smart contract developer, you should use Etheno to test your contracts. If you are an Ethereum client developer, you should use Etheno to perform differential testing on your implementation. Etheno runs a JSON RPC server that can multiplex calls to one or more clients. API for filtering and modifying JSON RPC calls. Enables differential testing by sending JSON RPC sequences to multiple Ethereum clients. Deploy to and interact with multiple networks at the same time. Integration with test frameworks like Ganache and Truffle. Run a local test network with a single command. Use our prebuilt Docker container to quickly install and try Etheno. Etheno can be used in many different ways and therefore, has numerous command-line argument combinations.Starting Price: Free -
