ACI Developer API

The ACI Developer API enables integration of Aethon Credit Intelligence (ACI) Framework scores into external platforms, providing real-time, deterministic, and methodology-versioned credit scoring data. Designed for institutional subscribers and credit analysts, this API facilitates programmatic access to provider scores and related credit intelligence outputs.

The API is accessible via REST endpoints, with authentication handled through API keys available in the user's Aethon Terminal workspace. Key endpoints allow users to list all provider scores, retrieve detailed score breakdowns for individual providers, and access information on upcoming issuances. Aggregate scores are also available through a public, unauthenticated endpoint. Optional parameters enable filtering by planner type (such as BTC, fiat, or stablecoin) and by issuance status or type. The API supports deterministic outputs, ensuring that results are consistent and reproducible, with all data versioned according to the underlying methodology.

js, browser environments, and both synchronous and asynchronous client usage. The TypeScript SDK is fully typed and has zero runtime dependencies, while the Python SDK provides methods to list provider scores and fetch detailed information for specific providers. Both SDKs include functionality for verifying webhook signatures.

The platform also provides agent workflow templates for large language models (LLMs), enabling analysts to generate risk summaries, investment committee memos, provider comparisons, and allocation risk assessments using deterministic fields from ACI score responses. These templates are designed to keep outputs strictly within the data provided, without extrapolation. Additionally, the MCP Server integration allows MCP-compatible AI agents, such as Claude or those implementing the Model Context Protocol, to connect directly to ACI scoring data, with available tools for retrieving and comparing provider scores, accessing score histories, searching providers, and obtaining methodology details.

A free tier is available with up to 100 requests per hour, while a professional tier increases this limit to 1,000 requests per hour. The API is positioned as a developer-focused tool for integrating institutional-grade credit intelligence into various financial and analytical applications.
