Error reference
Custom error codes explained
Blast supports two classes of APIs:
- JSON-RPC API
- Elrond REST API
Each of them has its own error response format.
Additionally, the JSON-RPC API can be queried via WebSockets, while the Elrond API does not expose this kind of endpoint.
When queried via HTTP both APIs return a status code and an API-specific JSON body.
The JSON-RPC API returns the same Error object on both HTTP and WebSocket endpoints.
Code | API | Description |
400 | JSON-RPC | Bad Request - Either invalid JSON-RPC body or requesting resources not available (i.e. method not on the whitelist). |
401 | All | Unauthorized - Request is not authenticated (the project ID is not valid or the network requested is not included in this project). |
403 | All | Forbidden - Exceeded capacity of API calls included in the current plan. |
429 | All | Too Many Requests - Reached limit of concurrent API calls allowed per second. |
500 | All | Internal issue while processing the request. |
Code | Message | Description | HTTP Status Code |
-32700 | Parse error | Invalid JSON. | 400 |
-32603 | Internal error | Internal issue. | 500 |
-32602 | Invalid params | Invalid method parameters. | 400 |
-32601 | Method not found | The method does not exist / is not available. | 400 |
-32600 | Invalid request | The JSON sent is not a valid Request object. In case of a batch request, if any of its sub-requests is invalid then the entire batch is invalidated. | 400 |
-32099 | Authentication failed | The request is not authenticated. | 401 |
-32098 | Capacity exceeded | Exceeded capacity of API calls. | 403 |
-32097 | Rate limit reached | Reached limit of concurrent API calls allowed per second. | 429 |
Code | Error | HTTP Status Code |
“unauthorized“ | “authentication failed“ | 401 |
“forbidden“ | “capacity exceeded“ | 403 |
“rate_limited“ | “rate limit reached“ | 429 |
