🟢get_grid
GET /: the grid the API key opens, by name.
输入模式
{
"type": "object",
"properties": {},
"title": "get_gridArguments"
}输出模式
{
"type": "object",
"additionalProperties": true,
"title": "get_gridDictOutput"
}🟢list_nodes(cursor, limit)
GET /nodes: the grid's nodes, each with its id, key and emb, in id order. `limit` is 1 to 1024; for the next page, pass the last id as `cursor`.
输入模式

"type": "object",

"result"
],
"title": "list_nodesOutput"
}🟢get_node(nid)
GET /nodes/{nid}: a node, with its key (null if it has none) and its embedding `emb`.
输入模式
{
"type": "object",
"properties": {
"nid": {
"title": "Nid",
"type": "string"
}
},
"required": [
"nid"
],
"title": "get_nodeArguments"
}输出模式
{
"type": "object",
"additionalProperties": true,
"title": "get_nodeDictOutput"
}🟡create_node(emb, key)
POST /nodes: add a node. An item gets a `key`, a path unique in the grid (e.g. "/items/42"), so searches can find it; a query gets none. `emb` is its embedding, 1 to 2048 floats from any model; use one model per grid. Returns its id and key (not its emb, to keep replies short; get_node has it).

],
"title": "create_nodeArguments"
}输出模式
{
"type": "object",
"additionalProperties": true,
"title": "create_nodeDictOutput"
}🔴update_node(nid, key, emb)
PATCH /nodes/{nid}: change a node. `key`: a new path, or null to remove it, so the node can no longer be found; leave it out to keep it. `emb`: a new embedding; leave it out to keep it. Its scores keep training, on the new embedding. Returns its id and key.

}🟡create_edge(nid, prefix)
POST /nodes/{nid}/edges, the search: from query node `nid`, the best node it has not been shown yet, among those whose key starts with `prefix` ("" for any), stored as a new edge: `id` is the found node's id, `score` is null until you score it (update_edge). Null when nothing is left. Call again for the next.
