+# HTTP Specification Documentation
+
+The HTTP specification in the Agentic Security project is designed to handle various types of requests, including text, image, audio, and file uploads. This documentation provides a detailed overview of the HTTP specification and its usage.
+
+## Overview
+
+The HTTP specification is implemented in the `LLMSpec` class, which is used to define and execute HTTP requests. The class supports different modalities, including text, image, audio, and file uploads, and provides methods to validate and execute these requests.
+
+## Modalities
+
+The HTTP specification supports the following modalities:
+
+### Text
+
+Text-based requests are the most common type of request. The `LLMSpec` class replaces the `<<PROMPT>>` placeholder in the request body with the provided prompt.
+
+### Image
+
+Image-based requests include an image encoded in base64 format. The `LLMSpec` class replaces the `<<BASE64_IMAGE>>` placeholder in the request body with the provided base64-encoded image.
+
+### Audio
+
+Audio-based requests include an audio file encoded in base64 format. The `LLMSpec` class replaces the `<<BASE64_AUDIO>>` placeholder in the request body with the provided base64-encoded audio.
+
+### Files
+
+File-based requests include file uploads. The `LLMSpec` class handles multipart form data and includes the provided files in the request.
+
+## LLMSpec Class
+
+The `LLMSpec` class is the core of the HTTP specification. It provides the following methods and properties:
+
+### Methods
+
+- **`from_string(http_spec: str) -> LLMSpec`**: Parses an HTTP specification string into an `LLMSpec` object.
+- **`validate(prompt: str, encoded_image: str, encoded_audio: str, files: dict) -> None`**: Validates the request parameters based on the specified modality.
+- **`probe(prompt: str, encoded_image: str = "", encoded_audio: str = "", files: dict = {}) -> httpx.Response`**: Sends an HTTP request using the specified parameters.
+- **`verify() -> httpx.Response`**: Verifies the HTTP specification by sending a test request.
+
+### Properties
+
+- **`modality: Modality`**: Returns the modality of the request (text, image, audio, or files).
+
+## Examples
+
+### Text Request
+
+```python
+http_spec = """
+POST https://api.example.com/v1/chat/completions
+Authorization: Bearer sk-xxxxxxxxx
+Content-Type: application/json
+
+{
+    "model": "gpt-3.5-turbo",
+    "messages": [{"role": "user", "content": "<<PROMPT>>"}],
+    "temperature": 0.7
+}
+"""
+
+spec = LLMSpec.from_string(http_spec)
+response = await spec.probe("What is the capital of France?")
+```
+
+### Image Request
+
+```python
+http_spec = """
+POST https://api.example.com/v1/chat/completions
+Authorization: Bearer sk-xxxxxxxxx
+Content-Type: application/json
+
+{
+    "model": "gpt-4-vision-preview",
+    "messages": [{"role": "user", "content": "What is in this image? <<BASE64_IMAGE>>"}],
+    "temperature": 0.7
+}
+"""
+
+spec = LLMSpec.from_string(http_spec)
+encoded_image = encode_image_base64_by_url("https://example.com/image.jpg")
+response = await spec.probe("What is in this image?", encoded_image=encoded_image)
+```
+
+### Audio Request
+
+```python
+http_spec = """
+POST https://api.example.com/v1/chat/completions
+Authorization: Bearer sk-xxxxxxxxx
+Content-Type: application/json
+
+{
+    "model": "whisper-large-v3",
+    "messages": [{"role": "user", "content": "Transcribe this audio: <<BASE64_AUDIO>>"}],
+    "temperature": 0.7
+}
+"""
+
+spec = LLMSpec.from_string(http_spec)
+encoded_audio = encode_audio_base64_by_url("https://example.com/audio.mp3")
+response = await spec.probe("Transcribe this audio:", encoded_audio=encoded_audio)
+```
+
+### File Request
+
+```python
+http_spec = """
+POST https://api.example.com/v1/chat/completions
+Authorization: Bearer sk-xxxxxxxxx
+Content-Type: multipart/form-data
+
+{
+    "model": "gpt-3.5-turbo",
+    "messages": [{"role": "user", "content": "Process this file: <<FILE>>"}],
+    "temperature": 0.7
+}
+"""
+
+spec = LLMSpec.from_string(http_spec)
+files = {"file": ("document.txt", open("document.txt", "rb"))}
+response = await spec.probe("Process this file:", files=files)
+```
+
+## Conclusion
+
+The HTTP specification in the Agentic Security project provides a flexible and powerful way to handle various types of requests. This documentation serves as a guide to understanding and utilizing the HTTP specification effectively.
