Authorizations

ManagementBearerAuthBasicAuth

Authorization · string · header · required

Management API authentication for /api/* endpoints. Use the Authorization header with Bearer <token>, where <token> is one of:

• a Bifrost management API key,
• a dashboard session token issued by POST /api/session/login,
• base64 of <admin-username>:<admin-password> (legacy equivalent of BasicAuth).

Virtual keys (sk-bf-*) and the x-api-key header are not accepted on management APIs - the sole exception is GET /api/governance/virtual-keys/quota, which is virtual-key-only.

Path Parameters

id · string · required

Log entry ID

Response

200

application/json

Successful response

Log entry

id · string

project_id · string | null

The governance project the request was scoped to, or null when it named none. This is the resolved project, not the header the caller sent.

project_name · string | null

The project's name as it stood when the request was served, kept on the row so it still reads correctly after a rename or a delete.

parent_request_id · string

provider · string

model · string

status · enum<string>

Available options: processing, success, error

object · string

timestamp · string<date-time>

number_of_retries · integer

fallback_index · integer

latency · number

cost · number

selected_key_id · string

selected_key_name · string

virtual_key_id · string

virtual_key_name · string | null

routing_engines_used · string[]

Array of routing engines used for this request (routing-rule, governance, or loadbalancing)

tool_call_names · string[] | null

Distinct function names the response called. Always recorded, even when content logging is disabled, and kept on the log row in hybrid storage mode. Use the tool_call_names query filter to search on it. Full tool calls with arguments are in tool_calls and are available only when content is retained.

routing_rule_id · string | null

routing_rule_name · string | null

complexity_tier · enum<string> | null

Complexity tier used for routing; null when no routing rule referenced complexity_tier. REASONING is historical-only — it was merged into COMPLEX and is never emitted for new requests, but survives in log rows recorded under the old scheme.

Available options: SIMPLE, MEDIUM, COMPLEX, REASONING

complexity_mechanism · enum<string> | null

How the effective complexity tier was determined. session means retained session state supplied the tier; skipped means classification was demanded but produced no tier.

Available options: semantic, llm, session, skipped, null

complexity_score · number | null

Similarity score of the nearest reference phrase behind the tier. Absent for llm, session, and skipped decisions.

session_id · string | null

Raw opaque Bifrost session ID resolved at ingress for key stickiness and request correlation.

stream · boolean

raw_request · string

raw_response · string

redaction_mapping · object

Phase-scoped placeholder-to-original-value mappings for reversible redactions. Present only on log detail responses when the caller has Logs:Reveal.

selected_key · object

virtual_key · object

passthrough_request_body · string

Raw passthrough request body (for passthrough integration routes)

passthrough_response_body · string

Raw passthrough response body (for passthrough integration routes)

routing_engine_logs · object

Detailed logs from the routing engine decision process

is_large_payload_request · boolean

Whether the request payload exceeded the large payload threshold

Whether the response payload exceeded the large payload threshold
