Exploring Claude AI's Text API Endpoints:

1. Text Completion (Create)

This endpoint generates different creative text formats or completes your prompts based on your input.
Type: POST
JavaScript Example:

const apiKey = 'YOUR_API_KEY';
const url = 'https://api.anthropic.com/v1/messages';

const data = {
    format: 'text', // Specify "text" format for text generation
    prompt: 'Once upon a time, there was a brave knight...',
    max_tokens: 150, // Adjust for desired output length
};

const headers = {
    'x-api-key': apiKey,
    'Content-Type': 'application/json',
};

fetch(url, { method: 'POST', headers, body: JSON.stringify(data) })
    .then((response) => response.json())
    .then((data) => {
        console.log('Generated Text:', data.completions[0].text);
    })
    .catch((error) => console.error(error));

2. Code Generation (Create)

This endpoint generates human-quality Python code based on your natural language description.
Type: POST
JavaScript Example: (Note: Requires a paid plan with access to the code generation model)

const apiKey = 'YOUR_API_KEY';
const url = 'https://api.anthropic.com/v1/messages';

const data = {
    format: 'code', // Specify "code" format for code generation
    prompt: 'Write a Python function to calculate the factorial of a number.',
};

const headers = {
    'x-api-key': apiKey,
    'Content-Type': 'application/json',
};

fetch(url, { method: 'POST', headers, body: JSON.stringify(data) })
    .then((response) => response.json())
    .then((data) => {
        console.log('Generated Code:', data.completions[0].text);
    })
    .catch((error) => console.error(error));

3. Information Extraction (Extract)

This endpoint extracts relevant information from factual text passages, like key dates or locations.
Type: POST
JavaScript Example: (Note: Requires a paid plan with access to the information extraction model)

const apiKey = 'YOUR_API_KEY';
const url = 'https://api.anthropic.com/v1/messages';

const data = {
    format: 'info', // Specify "info" format for information extraction
    prompt: 'The meeting will be held in San Francisco on Monday, December 11th at 10 am.',
};

const headers = {
    'x-api-key': apiKey,
    'Content-Type': 'application/json',
};

fetch(url, { method: 'POST', headers, body: JSON.stringify(data) })
    .then((response) => response.json())
    .then((data) => {
        console.log('Extracted Information:', data.completions[0].info);
    })
    .catch((error) => console.error(error));
