Create services

Lists the instrumented services seen in the window, each with the request profile of its entry-point spans: p99 and average latency, call and error rates, and the entry-point operations the numbers were computed over.

Field	In	Type	Required	Description
`end`	body	string	—	End is the window's end, epoch nanoseconds as a string.
`start`	body	string	—	Start is the window's start, epoch nanoseconds as a string.
`tags`	body	o11y.O11yServiceTag[]	—	Tags narrow the spans counted, each a span-attribute predicate.
`tags[].BoolValues`	body	boolean[]	—	BoolValues are the boolean operands, when the attribute is a bool.
`tags[].Key`	body	string	—	Key is the span attribute to test.
`tags[].NumberValues`	body	number (double)[]	—	NumberValues are the numeric operands, when the attribute is a number.
`tags[].Operator`	body	string	—	Operator is how to test it, e.g. in, not_in.
`tags[].StringValues`	body	string[]	—	StringValues are the string operands, when the attribute is a string.
`tags[].TagType`	body	string	—	TagType says which plane the attribute lives on, e.g. tag or resource.

Response

Status	Body	Meaning
`200`	o11y.O11yServicesOut	ok

200 body — 13 fields.

Field	In	Type	Always	Description
`data`	body	o11y.O11yService[]	—	Data holds one entry per service.
`data[].avgDuration`	body	number (double)	—	AvgDuration is their average latency, nanoseconds.
`data[].callRate`	body	number (double)	—	CallRate is calls per second over the window.
`data[].dataWarning`	body	o11y.O11yServiceWarning	—
`data[].dataWarning.topLevelOps`	body	string[]	—	TopLevelOps are the entry-point operations the profile was computed over.
`data[].errorRate`	body	number (double)	—	ErrorRate is the percentage of calls that errored.
`data[].fourXXRate`	body	number (double)	—	FourXXRate is the percentage of calls that answered 4xx.
`data[].num4XX`	body	integer (uint64)	—	Num4XX is how many of the calls answered 4xx.
`data[].numCalls`	body	integer (uint64)	—	NumCalls is how many entry-point spans landed in the window.
`data[].numErrors`	body	integer (uint64)	—	NumErrors is how many of the calls errored.
`data[].p99`	body	number (double)	—	Percentile99 is the p99 latency of its entry-point spans, nanoseconds.
`data[].serviceName`	body	string	—	ServiceName is the service.
`status`	body	string	—	Status is "success".

Failure carries the platform error shape — see Errors.

MCP reaches o11y through the o11y tool, which names its 307 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_o11y_autocomplete_aggregate_attributes"
         }
       }
     }'
