| 200 | OK | Everything worked as expected. |
| 400 | Bad Request | The request was unacceptable, often due to missing a required parameter. |
| 401 | Unauthorized | No valid API key provided in the x-api-key header. |
| 402 | Request Failed | The parameters were valid but the request failed. |
| 403 | Forbidden | The API key doesn’t have permissions to perform the request. |
| 404 | Not Found | The requested resource doesn’t exist. |
| 409 | Conflict | The request conflicts with another request (perhaps due to using the same idempotent key). |
| 429 | Too Many Requests | Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. |
| 500, 502, 503, 504 | Server Errors | Something went wrong on The Swarm end. (These are rare.) |
