Description
The Parallel Decisions API is a web-based classification tool designed for developers who create software, enhance data processes, and build workflows for AI agents. When a request is made, it includes specific context along with one or more defined questions, and in return, the API provides structured answers complete with probabilities and references to relevant online sources. This functionality allows multiple questions to be grouped under a single context within one request, enabling various applications such as vendor or company evaluations, lead management, compliance checks, content moderation, and establishing guidelines for agents. By accessing real-time web data, it can evaluate facts that might have evolved since the last training of a model. Developers can interact with the API via a RESTful endpoint using an API key or utilize the web_decisions tool through Parallel's MCP server. To facilitate testing and integration, a hosted playground and comprehensive documentation are available for user convenience. Furthermore, this API empowers developers to make informed decisions by providing up-to-date information that enhances the reliability of their applications.
Description
Perplexity's Decisions API is designed for rapid and structured decision-making that can be directly utilized by software applications. Rather than producing unstructured free-form text, it interprets various inputs such as natural-language text, JSON, or images as a shared context and delivers typed responses accompanied by probabilities. Developers have the flexibility to append multiple named questions to a single input, selecting from three distinct question types. The "noul" type provides yes-or-no evaluations, offering the probability of a "yes" response ranging from 0 to 1. The "choice" type allows developers to specify options and returns the most probable selection, along with the probabilities for each option and a confidence measure. Meanwhile, the "score" type assesses content based on a predetermined rubric, delivering a probability-weighted score, the complete probability distribution, and a confidence level. This API is particularly suited for various applications including classification, routing, rubric-based grading, severity assessments, sentiment analysis, and any decision-making process that can be evaluated against a certain threshold, making it a versatile tool for developers. Additionally, its structured approach enhances the reliability of the decisions made by the software, ensuring that outcomes are both accurate and consistent.
