Problem

Response and request schema

Schema

object

RFC 9457 problem document used by every managed error response under /v1, regardless of which layer produced it. Content type is always application/problem+json. Clients branch on code, retain an unknown-code fallback, use status only for broad handling and must ignore unknown top-level fields. title and detail are human-readable English, may be clarified without versioning and are never parsed.

FieldTypeDescription
chargedboolean · required

Whether credits were charged for this request. Always false on an error response in v1; no error creates a debit or hold.

codestring · required

Stable machine code from the registered matrix. Codes are only added, never changed, within v1; clients retain an unknown-code fallback.

Pattern: "^[a-z][a-z0-9_]*$".

detailstring · required

Safe occurrence-level explanation. Non-normative and never parsed by clients.

errorsarray of ValidationError

Present only for field-level validation failures. Items use request-field order and contain at most 20 entries.

Maximum items: 20.

errors_truncatedboolean

May be true when more validation failures exist than the 20-item bound allows.

instancestring (uri) · required

urn:hippomundo:request:{request_id}. Never the request URL or query string.

request_idstring · required

Server-generated request identifier, equal to the Hippomundo-Request-ID response header.

retryableboolean · required

Whether retrying this occurrence without changing the business request may succeed. An occurrence-level recommendation, not permission for an unbounded loop; honor Retry-After and use exponential backoff with jitter on retryable server errors.

statusinteger · required

The HTTP status code repeated as an integer.

Minimum: 100. Maximum: 599.

titlestring · required

Short stable English summary. Clients do not branch on it.

typestring (uri) · required

Stable HTTPS documentation URI derived from code (https://enterprise.hippomundo.com/docs/errors/{code}). Never contains request data.
