Retrieve a graph

GET/graphs/{graph_id}

Retrieves a graph: what history it holds (retention) and how its nodes stand (counts), now or as of any retained event.

This is the cheapest overview of a graph: one small object however many nodes it has. Poll it with If-None-Match to learn when anything changes.

Path ParametersExpand Collapse
graph_id: string
Query ParametersExpand Collapse
as_of: optional string or number

Answer as of this point in the graph’s history: an event id (evt_…, the state just after that event) or a Unix time in milliseconds (the state after the last event at or before it). Leave it out for now.

Must be within the graph’s retention, else 410 outside_retention_window. To read several pages or objects at one moment, pass the as_of_event_id of the first response.

One of the following:
EventID = string
UnixTimeMs = number
Header ParametersExpand Collapse
"If-None-Match": optional string
ReturnsExpand Collapse
Graph object { id, as_of_event_id, counts, 6 more }

One of your account’s live shares, and how its nodes stand at as_of_event_id.

id: string

Unique identifier for the graph, gph_….

as_of_event_id: string

The event this graph’s counts are as of. Pass it as as_of to read other objects at the same moment.

counts: GraphCounts { agents, blocked, by_state, 3 more }

How many nodes the graph has, by kind and state.

agents: number

Nodes of kind agent.

blocked: number

Unfinished nodes waiting on another node.

by_state: object { canceled, completed, failed, 3 more }

Nodes in each state.

canceled: number
completed: number
failed: number
idle: number
input_required: number
working: number
nodes: number

Every node.

sessions: number

Nodes of kind session.

stale: number

Nodes that are stale: working, but silent too long.

created: number

When the share was made, in Unix milliseconds.

formatint64
last_event: number

When its most recent event happened, in Unix milliseconds.

formatint64
object: "graph"

String representing the object’s type: always graph.

retention: Retention { event_count, first_event_created, first_event_id, 2 more }

The span of history the site holds for this graph now, and so the range as_of can take. A live share keeps between 1,000 and 2,000 events, trimmed from the start as new ones arrive.

event_count: number

How many events are held.

first_event_created: number

When the oldest event happened, in Unix milliseconds.

formatint64
first_event_id: string

The oldest event you can read, or ask as_of. null while the graph has no events.

last_event_created: number

When the newest event happened, in Unix milliseconds.

formatint64
last_event_id: string

The newest event. null while the graph has no events.

source: "watch" or "paste" or "upload"

How the graph was shared. watch is a live share from agent-graph watch-remote; this version of the API returns only those.

One of the following:
"watch"
"paste"
"upload"
url: string

Where to see the graph in the viewer. Only the account that owns it can open it.
