# API Usage Examples

This document provides practical examples for using the Orchestrator API.

---

## Authentication

All API requests require authentication via API key in the header:

```bash
curl -H "X-API-Key: your-api-key" \
     http://localhost:8080/api/plans
```

## Plan Management

### Create a Plan

```bash
curl -X POST http://localhost:8080/api/plans \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key" \
  -d '{
    "creator": "user@example.com",
    "steps": [
      {
        "type": "borrow",
        "asset": "USDC",
        "amount": 1000,
        "from": "aave"
      },
      {

## Error Handling

All errors follow this format:

```json

  "message": "Invalid plan structure",
  "details": {
    "field": "steps",
    "issue": "Steps array cannot be empty"
  },

}
```

### Common Error Types

- `VALIDATION_ERROR` (400): Invalid input data
- `NOT_FOUND_ERROR` (404): Resource not found

## Rate Limiting

API requests are rate-limited:
- **Default**: 100 requests per minute per API key
- **Burst**: 20 requests per second

Rate limit headers:
```
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1642248000
```

---

## Webhooks

Register a webhook for plan status updates:

```bash
curl -X POST http://localhost:8080/api/webhooks \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key" \
  -d '{
    "url": "https://your-app.com/webhooks",
    "secret": "webhook-secret",
    "events": ["plan.status", "plan.executed"]
  }'
```

## Complete Example: Full Flow

```bash
# 1. Create plan
PLAN_ID=$(curl -X POST http://localhost:8080/api/plans \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key" \
  -d '{"creator":"user@example.com","steps":[...]}' \
  | jq -r '.plan_id')

# 2. Add signature
curl -X POST http://localhost:8080/api/plans/$PLAN_ID/signature \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key" \
  -d '{"signature":"0x...","messageHash":"0x...","signerAddress":"0x..."}'

# 3. Execute
EXEC_ID=$(curl -X POST http://localhost:8080/api/plans/$PLAN_ID/execute \
  -H "X-API-Key: your-api-key" \
  | jq -r '.executionId')

# 4. Monitor status
curl -N http://localhost:8080/api/plans/$PLAN_ID/status/stream \
  -H "X-API-Key: your-api-key"

# 5. Get receipts
curl http://localhost:8080/api/receipts/$PLAN_ID \
  -H "X-API-Key: your-api-key"
```
