Solution Overview

Problem

Generating suitable payloads for API function calls is challenging, especially when accessing data from disparate data sources, as users often struggle to correctly utilize APIs and identify failures prior to deployment.

Innovation Solution

A system utilizing a neural network-based text generation model, such as GPT-4 or LaMDA, generates payloads for API calls based on user queries, aided by API metadata and validation data, to ensure accurate and efficient API integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users directly utilize API function calls to access data from disparate data sources, then data integration capability is improved, but the complexity of correctly utilizing APIs and generating suitable payloads increases

Engineering Contradiction:
Improvedata integration capabilityVSAvoidAPI utilization complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system that includes a prompt generator and text generation model. This intermediary automatically generates API payloads by translating user intent into properly formatted API calls, thereby reducing the complexity of direct API utilization while maintaining data integration capability. The intermediary handles the complex tasks of payload generation, validation, and error handling.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service by allowing users to simply provide natural language queries or basic parameters, and the system automatically generates, validates, and executes the appropriate API calls without requiring users to manually construct complex payloads. The system serves itself by having the text generation model learn from validation feedback to improve future payload generation.

Inventive Principle:
Principle #25Self-service

2Device complexity

If users manually generate API payloads without assistance, then system simplicity is maintained, but deployment errors increase and reliability decreases

Engineering Contradiction:
Improvesystem simplicityVSAvoiddeployment accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs preliminary actions by generating and validating API payloads before actual deployment. The validation data and error handling mechanisms check payloads in advance, identifying potential errors before they cause deployment failures. This preliminary validation improves reliability without significantly increasing system complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback loops where validation results and error messages are used to improve future payload generation. The text generation model learns from validation feedback, and error handling mechanisms provide corrective information back to the system, continuously improving deployment accuracy while maintaining a relatively simple user-facing interface.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If comprehensive validation and error handling are implemented for API calls, then deployment accuracy is improved, but the complexity of the payload generation system increases

Engineering Contradiction:
Improvedeployment accuracyVSAvoidvalidation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies partial validation by focusing on the most critical aspects of payload correctness based on validation data. Rather than implementing exhaustive validation of every possible error condition, the system targets the most common and impactful errors, achieving high deployment accuracy with moderate system complexity. The validation is tailored to the specific API and data source being accessed.

Inventive Principle:
Principle #16Partial or excessive action
