REST API с AI: как агент подключается к любому сервису без кода (EN)

```json { "title": "REST API with AI: How an Agent Connects to Any Service Without Code", "content": "## REST API with AI: How an Agent Connects to Any Service Without Code\n\nImagine: you want your AI agent to automatically create tasks in Trello from emails, update CRM, or send reports to Slack. Previously, you needed to hire a developer and write hundreds of lines of code. Now, the AI agent does it itself — it writes the code for you, using only **REST API** and your credentials.\n\nIn this article, we'll break down how an AI agent connects to any service via REST API **without a single line of code written by a human**. You'll learn how it works, what credentials are needed, and how to automate integrations in minutes.\n\n## What is REST API and Why Does an AI Agent Need It?\n\n**REST API** (Representational State Transfer) is a standard way for programs to communicate via HTTP requests. Almost every modern service (Google, Salesforce, Notion, Telegram) has a REST API for integrations.\n\nThe AI agent uses REST API as a \"remote control\":\n- Sends GET requests to retrieve data\n- POST requests to create resources\n- PUT/PATCH to update\n- DELETE to remove\n\n**Example:** An AI agent can retrieve a list of all contacts from HubSpot by sending a GET request to `https://api.hubapi.com/crm/v3/objects/contacts`.\n\n## How Does an AI Agent Connect to an API Without Code?\n\nThe process looks like this:\n\n1. **You specify credentials** (API key, token, or OAuth token)\n2. **The AI agent analyzes the API documentation** (or uses built-in templates)\n3. **Generates HTTP requests** on the fly\n4. **Executes them and returns the result**\n\n**Important:** The AI agent does not require you to write code. It creates the code itself (in Python, JavaScript, or Curl) and executes it in a secure environment.\n\n### Types of Credentials for REST API\n\n| Type | Example | For Which Services |\n|------|--------|-------------------|\n| API Key | `sk-123abc` | OpenAI, WeatherAPI |\n| Bearer Token | `Bearer eyJhbGci...` | GitHub, Notion |\n| Basic Auth | `username:password` in Base64 | Legacy API |\n| OAuth 2.0 | Client ID + Secret | Google, Salesforce |\n\n## Step-by-Step Integration: Example with Trello\n\n### Step 1: Get Credentials\n- Go to [Trello Power-Ups Admin](https://trello.com/power-ups/admin)\n- Create a Power-Up, get your **API Key** and **Token**\n\n### Step 2: Give a Command to the AI Agent\n\nExample request in natural language:\n> \"Create a task 'Update Report' on the 'Marketing' board and add a description 'Do by Friday'\"\n\n### Step 3: The AI Agent Generates and Executes Code\n\nThe agent automatically:\n1. Determines the endpoint: `POST /1/cards`\n2. Forms the request body with the necessary fields\n3. Adds the header `Authorization: OAuth {token}`\n4. Sends the request\n\n**Result:** The task is created in 2 seconds, you didn't program anything.\n\n## Top 10 Services for Integration via AI Agent\n\n1. **Slack** — sending messages, searching channels\n2. **Google Sheets** — reading/writing spreadsheets\n3. **Notion** — creating pages, databases\n4. **HubSpot** — managing contacts and deals\n5. **GitHub** — creating issues, viewing repositories\n6. **Salesforce** — working with CRM objects\n7. **Jira** — task management\n8. **Mailchimp** — email campaigns\n9. **Shopify** — order management\n10. **Telegram Bot API** — sending messages\n\n## Security: How Does the AI Agent Store Credentials?\n\nReliable AI agents (e.g., Asibiont) use:\n- AES-256 encryption for key storage\n- Never transmit credentials in plain text\n- Execute code in an isolated sandbox\n- Log all requests for auditing\n\n**Tip:** Use **read-only tokens** for test integrations — this minimizes risks.\n\n## Common Errors and Their Solutions\n\n| Error | Cause | Solution |\n|--------|---------|---------|\n| `401 Unauthorized` | Invalid token | Check credentials and expiration |\n| `403 Forbidden` | No access rights | Grant the necessary scopes in OAuth |\n| `429 Too Many Requests` | Rate limit exceeded | Wait or increase the limit |", "excerpt": "Imagine: you want your AI agent to automatically create tasks in Trello from emails, update CRM, or send reports to Slack.
