## Overview
This API provides a Hypermedia-driven interface (HATEOAS) to interact with Ghidra's CodeBrowser, enabling AI-driven and automated reverse engineering workflows. It allows interaction with Ghidra projects, programs (binaries), functions, symbols, data, memory segments, cross-references, and analysis features. Programs are addressed by their unique identifier within Ghidra (`project:/path/to/file`).
This API provides a Hypermedia-driven interface (HATEOAS) to interact with Ghidra's CodeBrowser, enabling AI-driven and automated reverse engineering workflows. It allows interaction with Ghidra projects, programs (binaries), functions, symbols, data, memory segments, cross-references, and analysis features. Each program open in Ghidra will have its own instance, so all resources are specific to that program.

### Addressing and Searching
Resources like functions, data, and symbols often exist at specific memory addresses and may have names. The primary identifier for a program is its Ghidra path, e.g., `myproject:/path/to/mybinary.exe`.
Resources like functions, data, and symbols often exist at specific memory addresses and may have names.
- **By Address:** Use the resource's path with the address (hexadecimal, e.g., `0x401000` or `08000004`).
- Example: `GET /programs/myproject:/mybinary.exe/functions/0x401000`
- Example: `GET /functions/0x401000`
- **Querying Lists:** List endpoints (e.g., `/functions`, `/symbols`, `/data`) support filtering via query parameters:
- `?addr=[address in hex]`: Find item at a specific address.
- `?name=[full_name]`: Find item(s) with an exact name match (case-sensitive).

## Resource Types
Base path for all program-specific resources: `/programs/{program_id}` where `program_id` is the URL-encoded Ghidra identifier (e.g., `myproject%3A%2Fpath%2Fto%2Fmybinary.exe`).
Each Ghidra plugin instance runs in the context of a single program, so all resources are relative to the current program. The program's details are available through the `GET /info` and `GET /programs/current` endpoints.
### 1. Projects
Represents Ghidra projects, containers for programs.
- **`GET /projects`**: List all available Ghidra projects.
- **`POST /projects`**: Create a new Ghidra project. Request body should specify `name` and optionally `directory`.
- **`GET /projects/{project_name}`**: Get details about a specific project (e.g., location, list of open programs within it via links).
- **`GET /project`**: Get details about the current project (e.g., location, list of open programs within it via links).
### 2. Programs
Represents individual binaries loaded in Ghidra projects.
- **`GET /programs`**: List all programs across all projects. Can be filtered by project (`?project={project_name}`).
- **`POST /programs`**: Load/import a new binary into a specified project. Request body needs `project_name`, `file_path`, and optionally `language_id`, `compiler_spec_id`, and loader options. Returns the newly created program resource details upon successful import and analysis (which might take time).
- **`GET /programs/{program_id}`**: Get metadata for a specific program (e.g., name, architecture, memory layout, analysis status).
- **`GET /program`**: Get metadata for the current program (e.g., name, architecture, memory layout, analysis status).

- **`GET /functions/{address}`**: Get details for a specific function (name, signature, size, stack info, etc.).

5. Include pagination metadata (offset, limit, size) for collection endpoints
Endpoints requiring HATEOAS updates:
- /classes: Missing _links field
- /instances: Missing _links field
- /segments: Result should be a list, not an object
- /programs/current/functions/{address}/decompile: Result should include "decompiled" field
- /programs/current/functions/{address}/disassembly: Result should include "instructions" list
- /programs/current/functions/by-name/{name}/variables: Result should include "variables" and "function" fields
- /functions/{address}/decompile: Result should include "decompiled" field
- /functions/{address}/disassembly: Result should include "instructions" list
- /functions/by-name/{name}/variables: Result should include "variables" and "function" fields
This test suite enforces strict HATEOAS compliance with no backward compatibility.
