# API

REST API reference documentation. 147 services with authentication, endpoints, and gotchas.

## Setup

On first use, read `setup.md` for usage guidelines.

## When to Use

User asks about integrating a third-party API. This skill provides:
- Authentication documentation
- Endpoint reference with curl examples
- Rate limits and pagination patterns
- Common mistakes to avoid

## Architecture

```
apis/                    # API reference files by category
  ├── ai-ml.md           # OpenAI, Anthropic, Cohere, etc.
  ├── payments.md        # Stripe, PayPal, Square, etc.
  ├── communication.md   # Twilio, SendGrid, Slack, etc.
  └── ...

~/api/                   # User preferences (optional)
  └── preferences.md     # Preferred language for examples
```

## How to Navigate API Files

Each category file contains multiple APIs. Use the index at the top of each file:

1. **Read the index first** — Each file starts with an index table showing API names and line numbers
2. **Jump to specific API** — Use the line number to read only that section (50-100 lines each)
3. **Example:**
   ```bash
   # Read index
   head -20 apis/ai-ml.md
   # Read specific API section
   sed -n '119,230p' apis/ai-ml.md
   ```

## Core Rules

1. **Find the right file first** — Use the API Categories table to locate the service.

2. **Read the index, then jump** — Each file has an index. Read only the section you need.

3. **Include Content-Type** — POST/PUT/PATCH requests need `Content-Type: application/json`.

4. **Handle rate limits** — Check `X-RateLimit-Remaining` header. Implement backoff on 429.

5. **Validate responses** — Some APIs return 200 with error in body. Check response structure.

6. **Use idempotency keys** — For payments and critical operations.

## Common Mistakes

- Missing `Content-Type: application/json` on POST requests
- API keys in URL query params (use headers instead)
- Ignoring pagination (most APIs default to 10-25 items)
- No retry logic for 429/5xx errors
- Assuming HTTP 200 means success

## Scope

This skill is **documentation only**. It provides:
- API endpoint reference
- Authentication patterns
- Code examples for reference

The user manages their own API keys and runs commands themselves.

## External Endpoints

This skill documents external APIs. Example endpoints shown are for the respective service providers (Stripe, OpenAI, etc.).
