Today, I'm sharing a significant upgrade of the #OpenLedger Dev Docs.

#OpenLedger's developer documentation has recently undergone a significant upgrade! This update is not just a small tweak, but rather the launch of an entirely new API framework aimed at paving the way for AI and the blockchain economy. This document was updated on July 3, 2025, exactly two days ago, making it "fresh out of the oven!" The core of the upgrade is to provide more powerful tools, allowing developers to more easily build AI-driven applications while making the entire ecosystem more transparent and sustainable. This upgrade also reflects OpenLedger's evolutionary approach—not a one-time effort, but an ongoing iteration based on the actual needs of developers.

Detailed Explanation of the Three Major APIs
This upgrade brings 3 brand new APIs, each unlocking new gameplay for developers like "super weapons:"
Completions
- Function: Through the /v1/completions endpoint, developers can send prompts to any deployed SLM (Small Language Model) to obtain intelligently generated outputs.

Budget & Spend Tracking
- Function: Developers can track the usage costs of AI models in real-time through the /spend/logs endpoint.
- Highlights: You can view spending details by user ID, request ID, API key, or time period. Even cooler, the fees are directly allocated to data contributors and model developers, achieving a fair mechanism of "earn as much as you use." It's like a transparent "ledger" where it's clear who contributes and who earns!

Model Management
- Function: Through the /v1/models and /model/info endpoints, developers can browse all available models (including those created by themselves or contributed by the community) and obtain detailed metadata (such as pricing, inference modes, access groups, etc.).
- Highlights: Supports team range filtering and compatibility with OpenAI tools, providing developers with immense flexibility. It's like a "model supermarket" where you can easily pick any model or check any details!

How do these upgrades benefit developers?
The launch of these APIs allows developers to create smarter, fairer, and more worry-free AI applications:
- Control Upgrade: Developers can finely manage model selection and access permissions, like being in charge, taking control of the overall situation.
- Cost efficiency doubled: Real-time budget tracking avoids the "money-burning black hole," allowing for more precise resource allocation, saving money and worry.
- Transparency and Fairness: Through blockchain technology, data contributors and model developers can directly benefit, creating a "rewarding" ecosystem. Users can also see everything behind the AI, experiencing greater peace of mind.
- Development experience optimization: These tools simplify complex processes, allowing developers to focus on creativity rather than being hindered by technical details. It's like adding a buff to the "superpowers" of developers!
