AgenticAPI provides a powerful set of features to build action-oriented APIs tailored for AI agents and intelligent systems. These features enable developers to create intuitive, scalable, and agent-friendly interfaces that go beyond traditional RESTful APIs. Below is a summary of the core capabilities that make AgenticAPI unique.

• Custom HTTP Methods / Verbs
  Define action-oriented methods (e.g., SUMMARIZE, CHECK, NOTIFY) to reflect task intent, replacing generic CRUD operations with clear, purpose-driven endpoints.
• Action-Oriented Design
  Categorize operations into meaningful types (Acquire, Compute, Transact, Communicate, Orchestrate), aligning APIs with real-world tasks and agent reasoning.
• Semantic Discoverability
  Use OpenAPI extensions (x-action, x-category) to make endpoints machine-readable, allowing agents to dynamically explore and invoke capabilities without external documentation.
• Workflow Orchestration
  Chain multiple actions via the CHAIN endpoint to support complex workflows, such as fetching data, summarizing it, and notifying users, with built-in error handling.
• Type-Safe Payloads
  Leverage Pydantic schemas to ensure clear, validated inputs with intent modifiers (e.g., format, style), context references (e.g., document_id), and execution hints (e.g., output_format).
• Adaptive Responses
  Provide standardized outputs with execution clarity (status, next_action) and flexible formats (JSON, text), supporting agent usability and decision-making.
• REST Compatibility
  Alias action methods to traditional REST endpoints (e.g., POST /document → SUMMARIZE /document), ensuring seamless integration with existing systems.
• Scalability and Performance
  Built on FastAPI for high-throughput, asynchronous processing, with rate limiting to ensure fair usage.
• Extensibility
  Support custom methods and categories, enabling tailored solutions for specific domains or use cases.
• Planned Enhancements
  Future features include test mode for action simulation, intent weighting for action optimization, and OAuth2 security for restricted access.
