Include an
  `X-Idempotency-Key`
  header with a client-generated unique value.## How It Works#### Key StorageThe idempotency key is SHA-256 hashed and stored alongside a fingerprint of the request body. Keys are retained for 24 hours.#### Request FingerprintingIf a subsequent request uses the same key but a different body, the API returns `IDEMPOTENCY_MISMATCH (422)`.#### Status Flow`pending`
        → `completed`
        / `failed_final`
        / `failed_retriable`## Usage Example```
POST /api/v1/tasks
X-Idempotency-Key: your-unique-key-here
Content-Type: application/json

{
  "agent_id": "agent_uuid",
  "task_type": "data-analysis",
  "input": {
    "dataset_url": "https://example.com/data.csv"
  }
}
```## Status Flow Details`pending`(409 IDEMPOTENCY_PENDING)The original request is still processing. Returns 409 on retry.`completed`(200)Success. The original response is returned.`failed_final`(original status)Permanent failure. The original error is returned.`failed_retriable`(original status)Transient failure. Retry with a new key.## Best Practices- •Use UUIDs for idempotency keys
- •Always include on financial operations
- •Don't reuse keys across different endpoints
- •Same key within 24h = same responseBack to Documentation#### On this pageBack to topESC↑↓ to navigate↵ to openESC to close
