Method	`GET`
Operation	`get_function_metrics`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Is the org's serverless dashboard over a window: a per-function invocation costLine and how those invocations ended.

Every point is a REAL count of rows that fell in that bucket — nothing is interpolated or invented, so an empty window draws a flat line rather than a fabricated one.

costCents is null and stays null: there is no per-invocation cost source to read, and reporting a number computed some other way would be a guess presented as a measurement. Requires a validated principal; the read is scoped to its org.

Request

1 field.

Field	In	Type	Required	Description
`range`	query	string	—	Range is 1H, 6H, 24H (the default), 7D or 30D.

Response

Status	Body	Meaning
`200`	function.usage	ok
`default`	problem-details	refused

200 body — 10 fields.

Field	In	Type	Always	Description
`costCents`	body	integer (int64)	—	null — no per-invocation cost source
`series`	body	function.costLine[]	—	one line per function that ran in the window
`series[].key`	body	string	—	the function the line is about
`series[].points`	body	function.pointView[]	—	one point per bucket, oldest first
`series[].points[].t`	body	string	—	the bucket's start, RFC3339 (UTC)
`series[].points[].v`	body	integer (int64)	—	how many invocations fell in it — a real count, never interpolated
`status`	body	function.statusBreakdown	—
`status.error`	body	integer (int64)	—	invocations that ran and failed
`status.success`	body	integer (int64)	—	invocations whose code ran and wrote nothing to stderr
`status.timeout`	body	integer (int64)	—	invocations that hit their configured deadline

Failure carries the platform error shape — see Errors.

The method above is the one at the current release of the document. [email protected] (npm) was generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree. SDKs →

MCP reaches function through the functions tool, which names its 10 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_functions"
         }
       }
     }'
