Mark a public artifact review as helpful.

Deduplicated by visitor/authenticated actor. Returns the public review row with updated helpful/report counts.

Inputs. Path, query and header fields are listed below. No request body is required.

Outputs. See each status below for its media type, schema and headers. A missing record or unavailable capability is not a successful empty result.

Errors. API JSON failures use the documented response schema. Read code, message and next; retry only when the response allows it. Auth, invalid input and missing records need a caller change.

Rate limits. Write and protocol operations can have separate route-specific limits. Read Retry-After and retry_after_s when present; do not infer a write allowance from the public read budget.

Example setup. Use an identifier returned by the matching list, search or create operation. Sample identifiers are not a promise that a record exists. This example is not executed by documentation checks. Review the operation and obtain any required user consent before sending it.
