Error Response Format
All Tiro API errors use the same JSON structure.{
"error": {
"code": 400001,
"errorType": "bad_request",
"message": "Human readable error message",
"detail": "Additional context or null"
}
}
Fields
| Field | Type | Description |
|---|---|---|
code | integer | 6-digit error code in AAABBB form: first 3 digits match the HTTP status, last 3 digits are a per-status serial. Use this for fine-grained client branching. |
errorType | string | Coarse-grained category derived from the HTTP status. Stable over time — safe for client branching. See table below. |
message | string | Human-readable error message. Not stable; do not use for branching. |
detail | object | string | null | Extra context included depending on the error. |
