The Steemit API ecosystem demonstrates robust performance and reliability, as evidenced by recent operational statistics. The system's uptime since November 24, 2024, spans over 44 days, with steady request rates averaging 4.41 requests per second (RPS) and peaking at 7.32 RPS over 5-minute intervals. The platform has handled a total of 16,850,746 requests during this period, reflecting its extensive usage and scalability.

Among the servers, https://api.justyy.com emerges as the dominant endpoint, processing 63.98% of all requests, equivalent to over 10.7 million calls, with an impressive success rate of 99.644%. Other prominent servers include https://api.steemitdev.com and https://api.steemit.com, handling 19.08% and 14.06% of traffic, respectively. Both these endpoints maintain high success rates above 98%, although they exhibit slightly higher error rates (1.528% and 1.448%, respectively) compared to Justyy's main API.

The API's load balancing mechanism effectively distributes traffic across multiple endpoints, including lesser-used servers like https://rpc.amarbangla.net, https://api.wherein.io, and others. These servers contribute marginally to the total traffic but serve as valuable redundancies, ensuring uninterrupted service during peak loads or outages.

Error counters highlight areas for potential optimization. The main contributors to error rates are https://api.steemitdev.com and https://api.steemit.com, collectively accounting for nearly 83,000 errors. While these rates are minor relative to their high request volumes, further refinements in request handling could improve the overall reliability of the network.

In terms of software versions, the blockchain operates on version 0.23.0, with the latest Steem and fc revisions, ensuring compatibility and security. The backend's commit source and Docker infrastructure ("latest" tag) underline the system's alignment with up-to-date development practices. Together, these statistics highlight a well-maintained, high-performing API infrastructure capable of supporting the dynamic demands of the Steem ecosystem.

The WhereIn API demonstrates its prominence within the Steemit network as it handles the majority of requests routed through its servers. With 82.08% of traffic directed to https://api.wherein.io, equating to 5,498,961 requests, this endpoint operates with impeccable reliability, achieving a remarkable 100% success rate and recording only two errors during its operational period.

While other endpoints like https://api.pennsif.net and https://api.moecki.online contribute to the system’s redundancy and load distribution, their traffic share is significantly smaller, at 12.93% and 2.2%, respectively. Lesser-utilized servers such as https://api.campingclub.me and https://rpc.amarbangla.net collectively handle about 4.65% of requests, reflecting a robust distribution strategy to manage smaller workloads and provide backup options.

The performance of https://api.steemit.com and https://api.steemitdev.com stands in stark contrast. Despite handling fewer requests (0.06% of the total traffic), these servers exhibit higher error rates of 7.164% and 5.45%, respectively. Such figures indicate potential inefficiencies in request processing, resulting in diminished success rates of 92.836% and 94.55%. Addressing these issues could further enhance the reliability of these nodes.

The overall traffic rate for the network is relatively modest, averaging 1.75 requests per second (RPS) over the uptime period. However, the 5-minute peak rate of 2.87 RPS demonstrates occasional bursts in activity. The consistent operation since November 24, 2024, underscores the stability of the underlying infrastructure, even with variations in load distribution.

The system's reliance on up-to-date blockchain software (version 0.23.0) and alignment with the latest Steem and FC revisions further ensures secure and efficient processing. Collectively, these statistics emphasize a high-performing API network with room for targeted improvements in specific endpoints.
